MIInspired by @ian_ruhter pinhole camera project, @aurelie_galibois and I decided to build and install a few of our own. We left them in place for a week, though you could easily leave them for months. The results turned out great! You can clearly see the sun’s daily path across the sky (solargraph). All you need is some photographic paper and two aluminum cans: one as the camera body, and another to cover the top opening.
If you want to try:
Make sure that the paper width is slightly less than the can circumference (about 7 inches width for the type of cans that I have used) and align the gap so that the paper doesn't obstruct the hole, I have failed to show that step in the video after the paper insertion.
For the type of paper, any light sensitive photo paper will work, like the Illford Multigrade RC Deluxe for example.
The safelight (not the black light as I mistakely put in the video) is not required, I have used it because I had it, but you can simply dim the light during the manipulations to reduce the light exposure.
The hole is covered with a tape but only during the manipulations, it is uncovered for the full exposure time. Exposure time should be one full day at the minimum and up to months and even years.
Since the exposure lasts for days, there is no development process required (no chemicals), but the photo paper needs to be kept in the dark after the scan if you want to keep it. Very nice step by step info on this site: https://www.skyatnightmagazine.com/advice/skills/how-to-make-a-pinhole-camera
