Pinhole help!

You can try Aluminum foil instead. That's in my experiment list with my DSLR.

Well no luck with the foil. I bet the pinhole has to move forward or backward from the sensor, not sure which way though.

What's the in camera aperture you're using?

I took the lens off, and put a piece of cardboard over the opening with a pinhole in it. I've heard of pinhole cameras for 35mm film, they're supposed focus everything I believe.

...pinhole cameras ... focus everything I believe.

Never tried to make a pinhole camera, but as far as I figure, the huge depth-of-field is due to the set up having a hugely long focal ratio (because of the tiny aperture). So, moving the pinhole farther away from the sensor might be best. Also, if that makes the exposures become too long (multiple seconds?), a tripod will be mandatory. I wonder if the quality (raggedness or smoothness) of the hole edge affects the image? Anyway, sounds like a fun project. Keep experimenting.

The distance of the pin hole should only change the size of the image projected on the plain of the film or sensor. In my own DSLR the camera likes to know what lens is on it and makes adjustment in software for it. Manual lenses still work but there are a few adjustments to make. Make sure everything on the camera is in a manual mode.

I have no experience with pinhole cameras but here is a link from Chris Marquardt who made his own pinhole camera. Chris has a podcast Tips From The Top Floor and I'm sure if you sent him a question on your problem he would send you his suggestion on a solution
