[QUOTE="Luke, post: 79333, member: 1531"] Hi Kristen, I'm dumb as a board about stuff like this, but I took a look at that website you linked to. It seems they're discussing a few different "versions" maybe of that "lens" you have....maybe they're different inserts (?). Do you know what f-stop equivalent is? If you're using the "zone plate" it looks they are calling it an f/46. Anyways.......here's a handy exposure calculator..... [url=http://www.calculator.org/calculate-online/photography/exposure.aspx]Photographic Exposure Calculator for Available Light[/url] Plug in the ISO of your film and the description of the amount of light you have and you'll get an approximate exposure. Hope that helps and good luck! Handheld looks possible under full midday sun. [/QUOTE]
