Finished the #projector stand for my #digital #enlarger for #cyanotype.

It's wobbly if you shake it, but overall sturdier than having it on the floor. It's more convenient having it as a table. I have a mini table to make tiny prints and a big table for large prints. Overall it's a good idea.

This weekend I worked a little bit on the #cyanotype #enlarger stand. I'm just going to put the #projector up as if was an enlarger light source over a table. So I got this slider locking system made out of scrap #wood from some recent house work. Last night I assembled it and it slides very nicely! It also locks pretty good .

Calibrating my #cyanotype #projector #focus. Holy moly! Look at that! My focus was at zero in visible light but in UV it's shown at 16 or more in this chart.

The card was at 45 degrees, the distance to 16 mark from 0 is 76mm so it means that I have to focus my projector 54mm in front of the actual photo.

This weekend I updated my #alternativephotography exposure system LOL APES for short. I mean its in C++ now and seems to be working on the #thinkcentre that I designated for #cyanotypes on #projector.

I wrote, with Mr Chat last name GPT, a #python program to #calibrate my #cyanotype and other #alternative #photography processes using my #projector. Basically you run the script and it makes little white squares every few seconds. When the screen is filled, you just removed the paper and go develop it. You can figure out how long it took to go from #paperwhite to full #blue. Sorry but this is an old projector and it's RGB which messes with the phone at 60Hz

#projector light is not really that intense. But I finally got good #ppe to do #alternativephotography with.

Usually I'm into #cyanotype but I am growing into the #chiba process. You can still only do one color at a time but at least it's not just blue. I do wonder if full color is possible with a projector system where you don't really have negatives. The negative is just an inverted version of the image you want.

On with my #uv #cyanotype #projector experiment. Look at that! A simple polished reflector made from an aluminum can can definitely focus a light beam. This was just a simple experiment. I need to 3D print supports to control the curvature and make it #parabolic. Two of these can be used to focus light from an LED lamp to the DMD chip to make an image. I wonder how terrible that image will be. But also it could be controlled by an #aperture.
