So dont forget - today is Worldwide Pinhole Day ( http://www.pinholeday.org/ ), and since my Diana has a pinhole setting, I'm giving it a try again. Last years Pinholes turned out pretty good, if really experimental - but I'm still way new to this and I have no idea if my pictures will turn out any good or if I'm just wasting film. But hey, learning new things is a always a good idea!

Anyone else ever done pinhole photography? Someone with some pointers would be nice. On the other hand, any other brave souls gonna go build their own pinhole camera and try it out with me?

I'd post a couple of examples from last year's effort, but the ability to post an image around here sucks ass - so here's the direct links to the photos:

Very cool Tony!  I understand folks enthusiasm for experimentation with these 'old school' kinds of media (I have an acq. who went back to tin and silver etches!) but it's not for me.  I like seeing other folks results tho!  But it looks like fun, and if you are enjoying it keep it up!

Did a little on grad school: it's a common demo for physics and optics undergrads. I should review my notes, but I believe the means to optimal results are to have a pinhole size and film plane distance so the diffraction spot size is the same as the pinhole size. It sounds comes, but it's a simple calculation if you know the pinhole size. And then you experiment with exposure times to get the best results. We used self-developing black and white film. That was 15+ yrs ago :) Google pinhole camera or camera obscura for more info.
