I have been doing some pinhole camera shots with my teacher in the darkroom and whatnot and he was telling me that I could do it on my DSLR. He wasn't sure how to for he has never done it but he siad that i should be able to. I want to try it. Is there anything I need to do special for it. I want to try it to see what I get! Help me!!!!

These are all of the steps i took to make a pinhole camera with my nikon.

1) Poke my body cap with a tack.... DONE.


As long as your in manual mode it will work fine :)

Here is a tutorial on DIY pinhole camera, just using your DSLR :D

PS. Make sure to take the body cap off the dslr first :D

For a video that wasn't made by someone labelled "Internet Freak", watch this video. It also showes how to make the hole even smaller, which, I think, leads to sharper results. The part that's really about the pinhole camera starts at 07:43 :wink: . It doesn't show you how to do it step-by-step, but it gives a good tip.

What is it excactly? I mean, it's obcious what the physical thing is, but why do you wanna do that? You can just do it in postprocessing, can't you?

Its really more for the sheer fun of taking a picture w/o a lens.

And as the guy in the video said, shooting photos at extremely small apertures.
It will be kind of like an extreme pancake lens, and really cheap as well.

Question: Does anybody know what the equivalent 'focal length' of a body-cap-pinhole camera like this would be? And if you positioned the cap (with a round tube) further away from the camera, would that 'focal length' change?

I need to do some thinking to prove it, but I think the focal length would be related to (if not actually) the distance between the pinhole (effectively the lens) and the sensor. A practical proof would be to work out the angle of the corner of the triangle created by the pinhole and the two sides of the sensor. Then find the equivalent focal length lens that has that angle.

Hmm i recall a tutorial where a guy made a zoom pinhole lens.. he like took a paper towel roll and toilet paper roll and put one inside the other and then painted it black inside and out (to avoid and light reflecting) and put a piece of tinfoil covering the top and poked a super small hole in it.. then cut out his body cap and fit the tube on that and light sealed it by spray painting the connection black too... and he had a zooming pinhole lens and it gave some pretty sharp results.. pretty cool stuff.

I couldn't resist making one after this thread. I have a spare T-mount, stuck some black card on the front and made a hole in it.

Effective spec: 56mm f/91. Turns out the focal length is the distance from sensor plane to hole. Aperture I measured by taking a macro of the hole next to a ruler, was approximately 0.6mm.

My cam with pinhole
Example 1: First light! ISO3200 1/10s
Example 2: This seems familiar... ISO400 10s

I found myself reaching for the focus ring after seeing these pics :D And I think I need a dusting...

Oh, I didn't see this until after I had made it... maybe I can build a better mk2 later.

Indeed cool stuff. Sounds like a nice experiment. I'm going to need more body caps though... :D
Nice to see you've gone ahead and made yourself a pinhole lens popo! The results are, well, not bad for a camera without a lens, I guess. Not as sharp as I had expected though.
