pinhole cameras

Anonymous Sun 12 May 2024 23:13:00 No.4313143 View View Reply Original Report

I've been trying to get into pinhole cameras lately. Does any anon here ever practiced solargraphy? Need some tips and tricks.

Only quick attempts, while making a pinhole out of a Fed 2 box

Its a lot of fun, use ilford photo paper and it's cheap too

If I remember correctly, using an aluminium can is one of the best ways to set up one of these; cut off the top, put photo paper in, place and unmask pinhole, wait a year and come back, no processing necessary before scanning

Making the pinhole is the hardest part

I've made two for a photography course and I also have one filming right now since the new year, planning to stop filming in midsummer.

I've used a film canister for my solargraphs. Cut a square hole to the side and put a piece of aluminum or similar material where you make the hole.

Whatever material you use, try to keep the hole as small as possible and clean the edges with sandpaper.

that's when you realize a 0.3mm hole is fucking hard to make by hand, and that's almost the minimum to get any resolution

Though nice job on yours, it looks pretty great
Do you have a pic of the cannister after you modified it?

Pic was taken with the one on the right. Left was okay too but a bit more blurry. I used a regular pin needle to make the hole.

Here's the one taken with the left one.

Pictures were digitized with a regular DSLR with two lights pointing the photo paper in a 45 degree angle. Exposure checked with a gray paper beforehand.

How long did you expose these for? Judging by the sun rings I'd guess around 3-4 weeks, right? Also, did you develop them or just scanned them as they are?

I wonder where did those white marks come from

About three weeks is correct, since the exposing time was tied to the duration of the course. I scanned them as they were, no need to develop solarographs.

I know some people do develop solargraphs but if I recall correctly that's if you just use one of those semi-diy pinhole boxes for 20-30 seconds of exposure.

Film photography is chemistry
