small aperture experiment

I modified my Sears Tower One-Twenty with a pinhole-sized aperture made by poking a hole with a sewing needle in a scrap of aluminum foil. I was guessing about the aperture size (around .5mm) and using a lookup chart for exposure times, which ranged from 4 seconds to 8.5 minutes (during which time I had to hold the shutter open with my finger, since there's no Tripod setting). I shot at 200 ASO and had the lab cross-process the film. I really couldn't ask for better results.

    Good colours, and good sharpness for the size. I sometimes think I should modify my Brownie to use a pinhole too...

    @adash It was shockingly easy, entirely temporary, and completely obviated a pretty major lens defect that was mushing up my pictures. I was going to take the lens out, but I couldn't figure out how to do it. No need, in my opinion.

    Sure, also the front plate of the Brownie falls off with a simple twist of the wrist. BTW, the exposure times you're giving are adequate for pinhole as is the aperture size, so basically you've got yourself a pinhole camera. Great photo (once again that is).

    @adash I was trying to be careful about describing it as a pinhole camera, as some pinhole enthusiasts seem to take offence at the idea that anything with a lens qualifies. Not sure why I care, now that I think of it...At any rate, thanks for the kind words!

    At that aperture the lens acts like a flat filter. It has almost no effect on the imaging properties of the pinhole, and I do believe you've got a legitimate pinhole camera. Regards and happy snapping!
