In a fit of insecurity, I decided to go with a precision pinhole for my experiments. I have yet to inspect anything I have taken with the ancient Foldex-20 I have refashioned into a pinhole camera, but I have my doubts about how well I “drilled” that last hole.
I ordered a .4 mm pinhole from Lenox Lasers. PinholeCalc seems to think that’s close to the optimal size.
Their bass-ackwards website doesn’t like Safari and isn’t all that thrilled with anything else. But the best part of it is that I griped about the shipping costs (US$16.54 on an US$18 item that weighs less than an ounce?) and got a reply that I could use USPS shipping for US$5. Cool.
They have a nice pinhole gallery there as well: check it out if you’re interested.
Now I just have to get up the nerve to mix up the chemistry and see what this roll has on it.
