Your House’s Electrical System and Catching Up

grouchyfarmer.com is now written by an actual real human being, not an AI! Now featuring actual genuine typos, mysspelngs, and much, much more!

So, on Monday, May 1, this is what it looked like outside my front door at 5 AM.

Yes, that’s snow. Nice weather we get here. This is why I haven’t been talking about gardening and bicycling and drone flying and putting up photos of pretty flowers and all that stuff. We had two or three days of summer like weather in March with temperatures in the 80s, and ever since then it’s been like this… cold, wet, cloudly, and now snow. Welcome to Wisconsin. Sigh… The weather has since gotten a bit better. It’s still been so cloudy with occasional rain that we’ve been making pretty much zero solar power. Again, sigh… Of course I shouldn’t complain. I have a friend who lives about 100 miles north of here in the upper peninsula of Michigan and over last week or so he got 52 inches of snow.

What I wanted to talk about is that someone asked why I need two inverters bolted to the wall and not just one. Just one of those inverters can supply 6.5 KW of power, as much as my big Generac gasoline generator, and enough to run almost the entire house as long as we’re careful. So why do I need two of them?

Partly it’s a question of capacity. 6.5 KW is a bit close to the edge for us, so to speak, at least as far as normal daily life is concerned. We may complain about our electric bill but we do like appliances like our coffee makers, our convection oven, etc. With just one inverter there would be times we would be pushing over that 6.5 KW limit. Two inverters give us a comfortable cushion.

The biggest reason though is that we also need 240V power to run some of the appliances in the house. For that we need both inverters. Initially I’m not going to be hooking any 240 appliances into this system because I don’t have eno0ugh batteries and solar panels to handle it, but eventually that’s going to change so I wanted a system that could be switched over easily in the future.

WTF is 240V split phase?

The average person doesn’t know, and doesn’t need to know, what actually goes on in the electrical system of the house. As long as your toaster or computer or TV works when it’s plugged into the wall and the lights turn on when the switch is flipped, that’s all they care about. And for most people that’s fine. But if you want to switch your home to an alternative energy system you need to know what’s going on behind the scenes.

While most of the systems in your house run on 120 VAC, in all likelihood there are some that require more power than a normal 120V line can supply. Things like electric water heaters, clothes dryers, electric stoves, well pumps, etc. will often run on 240V, not 120. The amount of power these appliances require would overload the normal 120V wiring systems in the house. So let me explain what’s going on without this getting complicated.

Well it’s going to get complicated anyway but let’s see what I can do.

What you have coming into your house is two, 120V AC power lines, not one. The two lines can be combined inside your circuit breaker panel to give you 240V to power more power hungry appliances like HVAC systems and clothes dryers.

If you took the front panel off of the main circuit breaker panel in your house it would looks something like the one in the photo below.

Now you’ll notice a couple of things right away if you look at that photo up there carefully. Note that there are two rows of circuit breakers, not one. There is a reason for that and I’ll come to that in a minute.

The next thing I want you to look at is right at the top center of that picture. You’ll see three thick wires coming in from the top. One is black, the 2nd is marked with red tape, and the third runs off to the right of center and is marked with white. Those three lines are what comes in from the service panel attached to the outside of your house and which, in turn, is fed from the utility company. The black wire and the red are the two 120V lines coming into the house and the white is the neutral line.

In your panel are two metal strips called busbars that the two hot wires (sometimes called legs because why not) connect to. Each busbar runs the length of the panel. The circuit breakers in the panel connect to those busbars to get the power that they then send out to the wires that lead to the outlets, lights, etc. in your house.

The circuit breakers on the left side of the panel get their power from L1, and the ones on the right get their power from L2.. Each busbar provides 120V.

So how do you get the 240V? Look at the top of the right row of breakers and you’ll see what looks like two breakers that are joined into one by a bar that connects the two switches together. That’s a 240V breaker.

Well, sort of. It doesn’t actually give you 240V. What it does is tap into both of the busbars at the same times, and lets you run two, 120V hot wires to whatever device that breaker breaker powers. The appliance that circuit energizes can combine both to provide 240V or use the individual 120V lines to power individual circuits in the appliance.

So if you want to design an alternative power system to run your whole house through your existing electrical system, you need a system that provides 120V to both L1 and L2, a 240 split phase system as they call it. And no, I can’t just feed 120V from a single source into both busbars at the same time because L1 and L2 are 180 degrees out of phase with one another and that is important. Or so they tell me.

Okay, so what’s with this phase stuff? Well it gets even more complicated and there is a hell of a lot of misinformation out there about what’s generally called “240V split phase”. There are people out there who will try to tell you that you need 240V split phase to power two phase motors, only there really aren’t any two phase motors out there and there haven’t been in many, many years. Or they’ll tell you you need split phase for electronics which is total BS because almost all modern electronics run off DC not AC…

Okay, look, the reason you have split phase coming into your home… Oh, hell, let’s look at what they’re talking about first of all.

AC stands for alternating current, and it’s called that because it, well, alternates. It doesn’t provide a steady positive voltage the way DC does. It alternates from plus to minus at 60 cycles per second. If you were to hook an oscilloscope up to an AC power line what you’d see on the screen is something like what you see in the picture over there on the left.

If you could look at both L1 and L2 at the same time on an oscilloscope it would look something like the picture over there on the right. The two are 180 degrees out of phase.

Why do we even use this system? It would take me pages and pages to explain all of that so I’ll leave it to you to go scurry over to Wikipedia or somewhere and find out for yourself.

So you have two, 120V lines coming in your house and they are 180 degrees out of phase with one another. Sort of. Kinda. And that’s important for, well, reasons, all right? And the two lines can be combined to give you 240V to power bigger appliances. Or not.

Are you confused yet? I am.

But let’s get back to my setup here. Each of the inverters will supply 1 of the two hot lines needed to get 240. And the two inverters “talk” to each other over a communications line so their sine waves are 180 degrees out of phase when in the split phase mode. Which is important for, well, for reasons. Or so they tell me. That’s what we’re stuck with.

But at the moment I don’t want to run any of my 240V appliances off this system. First of all that equipment sucks up huge amounts of power which would drain my batteries fast. The second issue is that my central air conditioning system quite possibly would require more amperage than my batteries can supply. EG4 recommends having at least 5 batteries in order to supply enough amperage to start up a big HVAC system like mine and I only have 3 at the moment.

To make a long story a bit shorter, I have two inverters because I’ll probably almost certainly need a system that can provide more load capacity than a single inverter would give me, and I eventually may want to expand the system to get 240V if I ever get enough batteries and solar panels up to support it.

But I’ve bored you long enough with this. let’s get on with it…

Catching up

One of the things I ordered for this system was a battery cabinet to hold the batteries that has its own built in busbar system for connecting the batteries, and which is also lockable to keep people from fiddling with things they shouldn’t. That was on backorder and I got an email from Signature Solar telling me I could either wait, or they could ship me a slightly different model cabinet. Like everyone else they’re still having supply chain issues. I told them I’d take the different model and that should be here Monday. I jury rigged things together so I could test the inverters and charge the batteries but it can’t stay that way. Once the cabinet arrives I can get the batteries properly configured and start putting everything together.

I have more solar panels on order because my 800 watts of solar is woefully inadequate to keep 15 KWh of batteries charged. Those are supposed to be coming May 15 so I’ll need to build frames to hold all of those.

Gardening Stuff

The weather hasn’t been very good but we’ve managed to get some work done out in the gardens. Once things warm up and the skies clear up we’re going to be really busy. We’re taking out a crumbling stone wall and replacing that, moving two of the raised beds to a new location and a bunch of other stuff going out there. MrsGF has had her indoor greenhouse going down in the basement for weeks already starting plants that will get transplanted outdoors as soon as the weather permits.

Artsy/craftsy stuff

The brewery called me the other day, asking if I’d make more drinks coasters for them. A couple of good friends opened a brewpub, something they’d dreamed of doing for years. So they bought a building with an existing tavern that had enough room for them to put in their brewery and then… Then Covid hit. And somehow they still managed to pull it off and even managed to pay the bills during that whole mess. And now they’re doing pretty well.

Anyway a while back I found some super cheap plain drinks coasters made from wood and some from paperboard and for the heck of it I fired up Photoshop and made some graphics, putting their logo on one side and an allegedly humorous illustration on the other and then used the laser engraver to burn it into the coasters. i thought they looked a bit on the unprofessional side but they were fun to do so I did a few. I never thought they’d actually use them in the bar. But they did, and apparently the customers loved them. And stole them. Which was okay because it’s good PR for the brewery. So I’ve done dozens, maybe a couple of hundred of these things over the last couple of years and I just got a request for more so I got that going on. People are easily amused, I guess.

But enough of this. I need to get going here. I’ve probably put you to sleep already with all of this. I know I’ve nodded off a couple of times myself…

Artificial Intelligence, Art and Controversy

I don’t often talk about computer technology and software here because A) it’s generally pretty boring, and B) there are far better sources for information about this stuff than me. But I want to talk about “artificial intelligence”, or AI as it’s known, because it has some serious implications for all of us as it comes into more widespread use. While I used to be a programmer I’m not so much interested in the technology of AIs as I am in the ethical and social implications of AIs, and that’s what I want to talk about briefly.

Take a look at that painting up there. It isn’t bad, really. Personally I’d like it if it were a bit brighter, but overall it isn’t horrible. It’s sort of a generic winter scene, peaceful, pleasant even.

Or what about this one —

Both of these paintings are originals that I just did in the last few days, but I didn’t make them in the usual way by applying paint to a surface or even a using a stylus on a drawing pad as I usually do. These were done by an app on my cell phone that is available for free on Apple’s app store called Draw Things. And as you can see it is pretty damn good. Well, sometimes. I will admit that about 8 out of 10 of the images it generates are, frankly, a bit, well, surreal. Like this one below.

I found myself wondering what kind of drugs my iPhone was on to make it produce something like this.

But that being said, that it works at all is, I think, a bit amazing. What’s even more amazing is that unlike some of the other art AIs out there which actually run on some massive server somewhere out there on the internet, Draw Things runs entirely on the phone, no external processing power required. You can try it yourself although I’ll warn you that your phone will need a lot of free memory (the libraries the software uses are a gigabyte+ in size and you need at least one for the program to work) and using the program frequently will suck up a hell of a lot of battery as well because it really makes that processor work hard.

When you run the program, what you do is type in words and phrases that verbally describe the scene you want painted. Let’s say you type in something like “A white cat sitting on a table with vases of flowers” as an example. What you get is something like this –

MrsGF thinks that image is just creepy but personally I think it’s kind of charming, but everyone’s tastes are different.

But these art AIs have also generated a hell of a lot of controversy as well, and for good reasons.

Yes, this one was generated by that app running on my cell phone.

First of all, artists, actual real world artists who create real world art, are very nervous about all of this and for very good reasons. There are thousands of artists out there who earn their living as graphic artists, illustrators, etc. for advertising agencies, magazines and the like. Publishers and corporations don’t give a fig about things like ‘artistic integrity’ or keeping illustrators gainfully employed. They only care about money. So if it comes down to paying an illustrator money to create a piece of artwork for them, or generating something essentially for free with an AI, guess which option they’re going to take? They’re going to go with the AI everytime.

Another controversy is how these AIs are trained. Before these things will work properly they have to be trained by feeding them literally millions of illustrations. They do this by scraping the internet for every image they can get their hands on, whether those images are protected by copyright or not. Under a strict interpretation of copyright law some claim that this is an illegal use of those copyrighted images. Others claim that this use qualifies as what is known as “fair use” and is legally and ethically acceptable. I’m not a lawyer and I’m not even going to try to figure out whether how these things are trained is legal or ethical or not.

Then there is the question of who “owns” the artwork generated by an AI. That image over there on the right was generated by Draw Things. So who actually owns the rights to that image? You could argue that the image was generated by my phone, using an application that I own, so therefore the image is mine and I own all rights to it.

But it isn’t as simple as that. These days you don’t actually “own” the software you are using. You’re merely licensing it. Basically you’re renting it. That’s been the case for decades now. Under the licensing agreement you agree to, and which you almost certainly haven’t bothered to read because you’d have to hire an attorney to figure it out for you, the maker of the software can set any conditions they like, and it is claimed that your mere use of that software means that you agree to all of the conditions in the license, whether you read them or not. It would be entirely within the realm of possibility for the maker of the AI you’re using to claim any and all rights to any artwork generated by the program. Unless you carefully read the fine print in the license agreement, you have no idea what you are agreeing to.

Some people have started to claim that the AI that generated the image “owns” it. The people who are making this claim either need to find a new hobby or stop taking whatever drugs they’re on because this is just stupid. An AI isn’t an intelligence, it is a computer program. Period. It is no more ‘alive’ than the old Eliza programs people were playing with back in the early days of computing. They’re little more than a complex series of “IF-THEN-ELSE” choices pre-programmed into a computer. Oh, all right it’s a lot more complex than that, but what it boils down to is that an AI is just a computer program like the one I’m using to write this. It is no more “intelligent” or self aware than the calculator you use to figure out your taxes.

The other thing that makes people very nervous is the fact that these things can be used to generate images that mimic specific artists. Want to have your very own original Van Gogh to hang on the wall? You can. These things can easily mimic the artistic style of most well known artists, living or dead. Living artists claim that this reduces the demand for their original artwork. People who like their work don’t need to buy an original or, more likely, an authorized print of the original work, they can use an AI to generate their own in the style of that artist.

I would imagine that the companies that have become wealthy selling stock images for use in publications, companies like Getty, are terrified by this kind of technology because it would very easily put them out of business. Let’s say you’re writing an article about, oh, shopping malls, and you want to put in a photo of a nice looking mall. Instead of going to one of these stock photo companies and buying one, just make your own. Like the one over there on the left. It took Draw Things a little over a minute to generate that. My cost? Zero. So why would anyone ever need to buy generic photos for illustrating articles any more? So let’s just say that investing your pension fund in companies that sell stock images probably isn’t a good idea.

And these things can be used to produce some not so nice images as well. Pornography, s0-called ‘deep fakes’ that portray celebrities, politicians or other well known persons in, oh, compromising positions, let’s call it, can all be generated with nothing but a program like this and a few written descriptions of what you want to see.

Some of the developers of these programs are starting to put filters into the systems to try to prevent or at least limit their capabilities so they can’t be usfed for illicit purposes, but that is ultimately futile. The technology is now out there. A lot of it is open source, meaning anyone can tinker with the underlying code. And there are versions of these programs already out there in the wild, so to speak, tweaked to specifically crank out these types of illicit images. Let’s face it, my friends, that’s what human beings are like. As soon as human beings developed things like writing, painting and drawing, they started using it to make porn.

There are already people out there demanding that something need to be done. Right now. By someone. Somewhere. Congress needs to act now! Act how, though? Ban the software? Sorry, that horse is already out of the barn. Thousands of people are already using it and hundreds are tinkering with the code to make it work even better.

What it all boils down to is that we have a lot of questions, a lot of ethical concerns, a lot of legal issues, and no real answers.

Please feel free to leave comments about this. I’m curious about what other people think of all of this and if anyone has proposed solutions to the problems.

Crazy Gardens and Stuff

Well, it’s official. The gardens here have gone nuts. This is probably the best growing season we’ve had since we moved into this place twenty or so years ago. The ornamentals, the vegetales, fruit, everything is looking pretty much spectacular.

We put in a few raspberry plants a few years ago because MrsGF’s sister gave us some, or we wouldn’t have bothered because I can’t (or am not supposed to, anyway) eat raspberries because I have diverticulosis and seeds and nuts can cause it to flare up. They sit in a little 8ft by 8ft patch of the garden behind the garage and they never really did that well. Until this year. For about a week now I’ve been picking a bowl full almost every day. They’re starting to slow down now and will probably stop producing by the middle of next week. Beautiful berries. Just wish I could eat ’em. Sigh…

I wasn’t going to put squash in this year because we haven’t had very good luck with them. But MrsGF found a different variety and put in a few plants and they’re doing good too. So far no sign of powdery mildew which pretty much ruined them last year.

We cut back on the number of tomato plants we put in. Last year we put in 12 or 14 plants and even though it wasn’t a very good year for tomatoes we still had more than we could ever possibly use. We only put in six plants this year in the raised beds and, well, so far it looks like we’re going to get more off those six plants than we got off a dozen of them last year. They’re just barely starting to come ripe now and I’m looking forward to having fresh tomatoes again.

And dear lord, the beans… We put in two varieties this year, a wax bean and some pole beans and we over planted those as well, it seems. The picking season is only just getting started and we already are getting more beans than we know what to do with and are looking for ideas of dealing with ’em. We’ll probably be giving away a lot of produce this year.

We put in a few different varieties of peppers, and it looks like they’re going to be ridiculously prolific as well. I’m not really sure exactly what variety these are. They were labeled “hot pepper”, but no variety was listed. They aren’t really hot, though. They’re actually quite mild. There is a tiny bit of heat there, but they aren’t even close to jalapeno peppers. Nice flavor, though. I think I might try canning some of these as pickled peppers.

I’m a bit concerned about the pear tree. It’s so loaded with fruit that branches that normally are about head height are already being pulled down almost to the ground by the weight of the fruit. I think I’m going to have to start snipping fruit off the branches I can reach before we start having branches breaking off.

I call this the finch corner. The cone flowers and sunflowers are finch magnets, or will be in a week or two as the seeds start to develop more. In a fairly short time this whole corner will be swarming with finches coming for the seeds. Great fun to watch out of the windows of the house.

Let’s see, what else… Oh, I made a – a thing again!

Bottom part is cherry, top is… Well, to be honest I’m not sure what kind of wood the top is made from. It’s a piece of scrap I found down in the shop and thought it made a nice contrast with the bottom. You can see an indentation around the middle of the bottom part. That is going to be stained very dark, almost black, to add contrast.

What the heck is it? Who knows? It isn’t useful as a bowl or anything. It’s a sort of, oh, art piece? Maybe? Kinda?

How To Draw A Cat (Recycled from old Tumblr account)

how to draw cat.png

I thought I’d put this one up here at the same time I posted it on the old Tumblr account but I can’t seem to find it here. So here you go, how to draw your very own cat.

I have no idea what was going through my head when I drew this. Sometimes weird stuff just pops up in my brain.

New Photos And How Stupid Am I (Very)

Even though today is officially the start of spring it sure doesn’t feel that way. Temperature around 34 degrees, cloudy… We’re impatient to get outside and do something again.

Nevertheless, I had the camera out and was taking some photos of the indoor plants, some of which are flowering right now.

Screen Shot 2018-03-20 at 1.09.48 PM

This guy is sitting in the kitchen window at the moment. Those flowers are only about a quarter of an inch across. Here’s another shot of a different cluster of flowers on the same plant with different lighting…

Screen Shot 2018-03-20 at 1.10.42 PM

That camera does a great job taking closeups like that.

Another plant in flower at the moment is this one:

Screen Shot 2018-03-20 at 1.11.15 PM

I love this plant. The color of the leaves, the texture, and those tiny little pink flowers that are about the size of the head of a pin. It’s a lot of fun.

MrsGF’s violets are in full bloom too right now:

Screen Shot 2018-03-20 at 1.10.54 PM

Then there’s this really weird plant…

Screen Shot 2018-03-20 at 1.11.54 PM

That’s Kai. I’m very surprised she held still long enough for me to get that photo. She usually runs away when she sees me with a camera.


And now, on to the stupidity…

Nothing makes me look dumber than when something goes wrong with my radio equipment sometimes. This one was a real gem, though.

For some reason the TS-990 decided to stop transmitting AM and I couldn’t figure out why. Everything seemed to be working just fine otherwise. I could still use SSB, the digital modes, FM, all were working fine. But when I keyed the mic using AM, it would go into transmit mode, but no signal.

I spent something like two hours this morning trying to diagnose what the problem was. As a last resort I got out my morse code key and hooked that up. Not sure why. Just was trying to eliminate other things as problems. I tried sending my callsign in CW and…

And nothing. Same symptoms as the AM problem. It went into transmit, but no signal, no power going to the antenna.

Hmph… I went on line and searched around, found out there was an update for the radio’s firmware, so I downloaded that and installed. That went well. In fact, better than well because now the noise blanker works the way it’s supposed to and some other little things were fixed. But same problem as before, no AM and no CW.

I pulled out the manual once more and started to dig through that and…

Oh. Oh, brother… All right, look, the 990 is a very complicated piece of equipment. I mean it has controls and knobs and buttons on it that I’ve never used in the almost four years I’ve owned the thing. So I suppose I can be excused for not noticing this.

Most of the knobs on the radio are “nested”, that is there is a central knob that controls one function, and an outer ring around the central knob that controls an entirely different function.

The Power knob which controls the rig’s output power is the central knob. The outer ring is something labeled “Car” which stands for carrier. The carrier setting is essential to transmitting in CW and AM modes. I normally have it set dead center right in the middle. But since I almost never do CW or AM I almost never touch it. But I do use the Power knob to adjust the wattage going out to the antenna or feeding into the amplifier.

Somewhere along the way, the Car knob got a bit sticky and started to track along with the Power knob when it was turned. But only in one direction: down. When I turned the power down, it was also dragging the carrier knob down towards zero, but not dragging it back up when the power was turned back up. Eventually the carrier was turned down to nothing. So without a carrier, there was no AM or CW.

Sigh… Spent more than two hours trouble shooting a problem that didn’t really exist. All I had to do was turn the Car knob back up to the center position and all was well.

And now I just found out my amplifier relay isn’t working… How did I get into this hobby in the first place?

Along The Roadside

Screen Shot 2017-08-03 at 5.54.50 AM

It was a glorious morning Wednesday when I went out not long after dawn. One of those glorious mornings when the rising sun seemed to be making everything glow.

My attempts at using the panoramic mode of the iPhone7’s camera have never been very good. The mode works, yes, but the results never seem to be that good, to be honest. The image of that meadow up there just doesn’t look that good. So let’s look at these instead: click on one of the images to start the full size slide show.

These, on the other hand, turned out pretty good, I thought. I have to admit that the iPhone 7 camera works pretty well under some conditions.

 

Stuff: New Photo Printer and the Bad Old Days

I’m a serious photographer and have been for something like 40 years. I’m not a professional, but I try to turn out photographs that are as good as I can make them. One of the problems photographers have always had is making good prints of the images they make, especially making prints that are larger than the usual snapshot sized print.

There are a lot of inkjet printers on the market that claim they are “photo printers”, a lot of them are really cheap, well under $100. But let’s face it, most of them aren’t very good, especially when you’re trying to make larger sized prints. The biggest size they can handle is the standard 8X10 or 8X11 sized papers, and the images they crank out aren’t that good when scaled up to that size, and all too often the inks and pigments used fade quickly when exposed to light.

Screen Shot 2017-07-18 at 6.05.49 AMSo I finally broke down and got a professional grade photo printer, the Cannon Pixma 100. It’s at the low end of the professional level printer. It retails for around $500, and can handle paper up to 13 X 19 in size, which is big enough for my purposes. It uses dyes rather than pigments. There is a big argument going on between the dye proponents and the pigment proponents about quality of the images, their long term stability, color, etc. and I’m just not going to get into that nonsense. As far as I can tell, the two different techniques are about equal when it comes to overall quality and the lifespan of the images.

Now there are a lot of printing services out there that will take your images and make larger format prints for you, and they do a decent job. But if you want to print a lot of images, it doesn’t take long before you realize that it’s a heck of a lot cheaper to do it yourself.

There was a bit of a learning curve as I figured out how to get the most out of the printer, but now that I’ve discovered the right papers to use (stick with the Cannon Luster line of paper, that seems to work best), the right settings, and how to properly tweak an image for printing, I’m more than satisfied with the results. Some of the ads I’ve seen for the Pixma line of printers claim “gallery ready prints” and they aren’t far off the mark on that claim.

All of this got me thinking about how photography has evolved in the last 40 years or so, and the advances in technology have been mind boggling when I stop and think about it.

Screen Shot 2017-07-26 at 6.43.14 AMWhen I first got interested in photography on a serious basis, a good 35mm camera would set you back about $350 for just the camera body. The lens was usually sold separately, and a good one could set you back more than what the camera itself cost. The first good 35mm camera we had was a Minolta XGM, an almost but not quite professional 35mm SLR camera. That cost me $345 back in 1981. By the time I got a decent lens, filters and everything else I needed, I think the grand total was about $800 for the whole package. And that’s in 1980 dollars. Adjusted for inflation I suspect that would come to around $2,000 today.

Screen Shot 2017-07-26 at 6.56.24 AMIt was, for it’s day, a very good camera, especially when compared to the crappy pocket cameras like the Kodak Instamatic with it’s even worse film loaded into those dopy cartridges which was the most popular mass market photography system at the time. They were horrible. The photos and negatives they turned out were even worse, thanks in part to poor manufacturing, poor materials, bad lenses, and the cheapest, nastiest film you could imagine. While it was good enough for a small, wallet sized image, if you wanted to blow it up to a larger size, forget about it. The film was so grainy the images were totally unacceptable if you tried to blow them up to anything larger than a 4X5 print.

While I’m on the subject of film, let’s continue along that line.

Ah, film — The good old days of 35mm film. Well, no, they weren’t all that good, the film days. In fact, they were bloody horrible, the film days. The photographers who wax poetic about the “good old days” of film and how wonderful they were probably never had to actually work with the stuff.

Screen Shot 2017-07-26 at 7.16.03 AMMost people bought film in small canisters like the one shown here. The body was generally made of metal and the end caps were plastic. Film was wound on a spool inside of the canister. You can see where the film comes out of the can on the right side of the cartridge, it’s that little brown flap. That’s the leader. A couple of inches of film stuck out.

You’d open the camera, drop the canister into a space in the camera, pull a few inches of film out of the cartridge, across the shutter opening, onto a take-up spool on the other side, thread the film onto that spool. Then close the camera up and wind several inches of film through to make sure the take-up spool had latched onto it. Oh, and there were slots in the edges of the film that had to fit onto small gears in the camera to pull the film through when you turned the film advance knob or lever. And hope like hell the those holes lined up right and didn’t strip out, because if they did, you’re film wouldn’t advance and you’d lose the entire roll of film.

Film was not cheap. It wasn’t wildly expensive, all things considered, but it wasn’t exactly cheap, either, and most photographers gave careful thought to what they were shooting because you couldn’t afford to waste film or processing. And you only had a very limited number of images per roll, usually 24-36 images.

Screen Shot 2017-07-26 at 7.17.12 AMPeople who did a lot of photography often bought film in bulk and loaded the canisters themselves using gadgets like the one here. This is a bulk film loader. Your roll of bulk film would go in the big end, and then you’d use the crank to wind it into your film canisters. It was a pain in the neck, but it did work, and it did help cut costs a bit. I used to do this and it worked fairly good most of the time. Well, sometimes. Maybe.

Oh, and I should point out that whenever you were working with film before it had been processed into negatives you had to do it in total darkness. And I mean total darkness. Any stray light at all would fog the film and ruin it.

Then there was the question of what kind of film to get. There were dozens of different kinds, some intended for general use, some intended for special purposes. There was slide film. There was print film. There was B&W and color. Films came in different grains, different speeds… The list goes on and on.

The most important was probably film speed. That’s what that big “400” is on the canister above, the ISO rating of the film. To keep things simple, ISO was a rating of how sensitive the film was to light, basically how quickly the film could capture enough light, so to speak, to make a usable image. Generally speaking, the bigger that number, the “faster” the film was, i.e. the more sensitive it was to light. The faster the film, the less time the shutter had to be open to allow the film to capture enough light to make a usable image. ISO 100 was the most common in use for hobby photographers, but it was considered a “daylight” film, in that it needed bright lighting conditions or use of a flash or strobe. Otherwise the shutter had to be open so long that you needed a tripod to keep the camera stable so the image wouldn’t be blurred.

ISO 400 was a much faster film that permitted faster shutter speeds, reducing blur, and reducing the need to use a flash or strobe in lower light conditions. But there are always trade offs. ISO 400 films were not as fine grained, didn’t give as good detail in the final image as the slower speed films did. It was also a bit more expensive. In the 1980s the technology and chemistry improved to the point where some ISO 400 films were almost as good as the ISO 100 films when it came to grain size and image quality and for general use most people had switched to the 400 speed films.

ISO ratings ran from about 30, a very, very slow film, up to about 1,600, if I remember right. And then there were tricks you could do to “push” film to a faster ISO rating through processing back in the darkroom. Some films could be push processed with some success, some couldn’t. And again there were tradeoffs. Image quality degraded rapidly when you push-processed film in most cases. I experimented with push processing, pushing 400 film up as high as 1600 or more for night photography, but the results were not very good.

Now, you’ve got the camera, you’ve got the lens, you’ve got the film. You’ve taken some photos, now, let’s take a look at them, shall we? Uh, well, no. Not yet. If you open up that camera at that point, all you’ll do is ruin the film and all of the photos you took.

Remember that canister, and the takeup spool and the gears and all that stuff inside the camera? Once you reach the end of the spool of film, now you have to wind all of it back into the canister before you can even open up the camera. You’d turn a little crank or knob on the camera to wind it back into the can. Once you did that you could take out the canister safely.

You now have to get the film processed into negatives and made into prints. Most people took them to a store where you’d stick it into an envelope with your name and address on it and it would be shipped off to a lab somewhere, and in a week or so you’d get your film back in the form of negatives, and a set of snapshots, small prints of the images you’d made. And the results were, well, terms like “generic” come to mind because all of that film was fed through massive developing and printing machines that used standard processing and exposure times for everything that was shoved through them. If al you were taking were snapshots of the family vacation, they were fine. But if you were a serious photographer and were making images that were in any way outside of the norm, well, forget it. That kind of thing meant shipping it off to a custom processing lab, which was expensive, or you did it yourself as I did.

First you had to get the film out of the canister. You’d pop the end off, pull the film out, and then…

Oh, did I mention that you have to do this in complete darkness? Yeah, you do…

Screen Shot 2017-07-26 at 7.19.13 AMYou then put the film on a special spool that fits inside of a developing tank. Once you get the spool in the tank and get it closed, you can turn the lights back on because the tanks were light proof.

Now comes developing. You mix up a witch’s brew of developing chemicals. Exactly what you used depended on the kind of film you were using. Pour it in the tank, then gently agitate the tank for the specified amount of time. Then you rinse it with clean water, take out the spool, and bingo, you have negatives. They have to hang up and dry, then you generally cute the long strip into shorter lengths with about four to six images per strip.

And you aren’t done yet. Now you have to take those negatives and make actual prints of them on special photographic paper.

And just as there were many different types of film, there were many, many different types of papers, and which one you used depended on the kind of film you were using, what kind of prints you wanted, what kind of surface you wanted the finished print to have… There were dozens of different kinds of papers for color and black and white.

Oh, and the paper has to be kept in totally light proof boxes, and can only be used in total darkness. Those “safety lights” you’d sometimes see in darkrooms that allegedly let you see what you were doing without damaging the paper? Uh, about those… They only worked with a very limited number of paper types, and even then, they had to be kept so dim they were virtually useless or the paper would be ruined. So most of us worked in complete darkness.

Now, to make a print, you need still more special equipment. You need an enlarger, a timer, and a laboratory that looks like it came straight out of the Mad Scientist’s Handbook.

Let’s look at enlargers first. Why do you need one in the first place? The reason is that 35mm film yields 35mm negatives. Which is why they call it 35mm film in the first place. Duh… Now you could make a print by just laying the negative on the paper and shining a light on it. But that will give you a 35mm print, and that’s just, well, silly, okay? You want something larger, like an 8X10.

Screen Shot 2017-07-18 at 6.24.54 AMSo, here’s an enlarger. I had a Durst enlarger back in the day. Mine was considerably more elaborate (and expensive) than the one in this ad.

How they work is the negative is placed in a frame that is inserted in the head. There is a lamp in the head which shines the light down through the negative, through a special lens, down onto the paper placed on the bed below. Enlargers could get as complicated and expensive as you cared to make them. Probably the most important part of the enlarger was the lens, because that determines the quality of the image that is projected onto the photo paper.

Now you also needed a timer, because that image had to be projected onto the paper for a specific period of time. Too short and the image would be pale and ghostly. Too long and you’d end up with a print that looked like it was taken at midnight or even completely black. Exactly how long you exposed the paper depended on a variety of factors; the film, the film density, how bright or dark you wanted the print, the kind of paper you were using. Proper exposure could take just a few seconds, or it could take many minutes depending on what you were doing and the materials you were using.

Screen Shot 2017-07-29 at 6.26.53 AMOnce you have the photo paper exposed with the enlarger you’re still not done. Now you have to develop the paper using a variety of different chemicals. You need several trays big enough to hold the paper, a dark room, timers, a sink, a water supply, and lots and lots of yummy chemicals.

The paper has to be soaked in various chemical solutions – developer, fixer, etc. for varying lengths of time until the image appears on the paper. Then it has to be washed in clean water and hung up to dry. Oh, and most of that has to be done in complete darkness as well. That photo up there is red because they’re using safety lights. But about 99% of the time you were working with film and papers that could only be handled in total darkness, and even the dim safety lights would ruin them.

Screen Shot 2017-07-19 at 7.07.58 AMNow the lab up there looks pretty good, it’s probably a professional or semi-pro lab. Most home darkrooms looked more like this because they were squeezed into basements, large closets, even special built rooms in spare bedrooms or wherever they could be crammed in. They were messy, smelly, nasty, and you were working with some pretty hairy chemicals sometimes, many of which were poisonous.

And this was just for B&W photography, by the way. If you wanted to do color, it required a whole different setup, with much more complex and expensive enlargers, processing tanks, timers, heaters…

Now I admit that every once in a while I feel a bit of nostalgia for the “good old days” of film photography. But then I take and aspirin, have a little lay down and I feel better and remember that the “good old days” were bloody awful. And I have gladly, even gleefully traded all of that for digital cameras and computers and modern photo printers.

Stuff, Nonsense, and More Garden Photos

Mr. Spiny, the cactus we rescued from the town compost pile, has gone totally goofy this year. He now looks like this:

IMG_0485.jpg

I counted around 13 flowers, with about a dozen more buds ready to flower in the next day or two. I kinda, sorta knew that cactus flowered, but I had no idea they did this! We thought it was a really neat plant before, but now– Wow.

Mrs. GF picked up a packet of old seeds on sale for a few cents earlier in the season, threw them in one of the gardens, and then these things came up —

I had no idea she did it so I was astonished and delighted when these brilliant orange poppies started to appear last week. The color on these guys is so intense they almost glow in the dark.

With some plants you don’t appreciate their beauty until you get up close to them and really look at them. Like the oregano we’ve been trying to kill off for years now. The stuff turned out to be horrifically aggressive, taking over the entire plot of ground, and even taking over the lawn in that area. And while it does smell amazing when I mow the lawn over there, we would like to grow something besides oregano there, so we’ve been rather ruthless in keeping what’s left in check.

But that very annoying plant, well, even it looks neat when it starts to come into flower as it is now.

The Fuji camera I use has a pretty darn nice macro-zoom lens on it and while depth of field and focus is a pain to get right when I get this close to something, the results are worth it.

Heck, even the lowly cucumber looks pretty when you get close to it:

Other stuff–

We’ve been going to state parks this summer. Wisconsin has one of the finest state park systems in the country. The places are absolutely beautiful.

Or perhaps I should use the phrase “had one of the finest state park systems”. The state government has decided, in its infinite stupidity, to cut off all funding for the entire state park system. It does not get any funding from the state any more and is going to have to survive entirely on entrance and camping fees, donations, and any other money it can scrounge up. I wouldn’t be surprised to find them out on the beaches with metal detectors looking for change people dropped to try to keep the parks running. The new paradigm down in Madison seems to be that if it doesn’t make a profit for someone who can funnel bribe money [ahem, excuse me] campaign contributions into their bank accounts or fund their PACs, it isn’t going to get any of our tax money. Sigh…
