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.

    @traaaart Thanks! The craziest part is that it actually worked. Everything was based on my wild guesses about the aperture size and adjustment to ASO for cross-processing.
