I'll post something found on google

What sort of film would you use? It's probably an obvious question, but surely you would need to extremely low sensitivity film (like iso >1) and a microscopic aperture pinhole thing?

I'm probably missing something here

Never tried. The sun patterns aren't unpredictable, but it's very nice to see how they draw the sky in a single frame.
also, what do you need to this kind of exposure?

Over such long timeframes I can imagine doing it with digital camera and a cheap trick. technically just take an ultralong timelapse sequence with a pic like every 3 minutes and then layering it.

Just looked it up, apparently it's done using a beer can (hence the curved shape of the image) and oldschool photo paper.

The paper is placed inside the pinhole beer can for six months, and instead of being developed at the end, it is merely scanned in a dark-ish room.

The paper is exposed for so long that a negative image becomes etched into it, no development required. Pretty neat

Anon you're blowing my fucking mind.

OP here, i've made this thread for advices because i want to try it. Apparently like >>2984074 said, it's possible by using only a beer can, there's a video tutorial. My main worry is the photo paper, i'm afraid that after 6 months it will be only an overexposed piece of paper without a real subject.
A nice thing to do is that everyone here make a beer can pinhole and we see results 6 months from now

as said before, you don't develop it - it gets enough light over the span of the project that the image becomes visible on its own, enough silver to form a visible negative. Photo paper doesnt darken that fast - take a piece and leave it in some place like a corridoor, where direct sunlight doesnt reach it, and see how long it takes to turn black. report back when you get bored waiting.

People need to understand the difference between overexposing the latent image and darkening undeveloped paper.

Thank you for your tips, anon! I'll do it as soon as i can

>>2984103
Not anon but !kurwaRB7YU, sorry!

what about doing a bulb exposure of a camera with a bunch of nd filters? Make a box which is on a timer to close in 6 months

you'd probably have to take some test exposures to get some averages on the amount of light you'll get per day, then calculate how long the exposure could actually be before the film gets overexposed

some other photos i found

This seems very interesting! I'm in. I absolutely don't know anything about photographic paper but I want to try.

>>2984100
Im game to try it

If you post anymore info id love to get started I have some fresh fuji crystal archive lustre paper lying around. I may build a full 8x10 enclosure and try that along with a can.
