Hi everyone, I'm new in APUG, and in Pinhole photography. I've made a couple of cameras that worked pretty well, and now I wanted to make a new one. The thing is that I want this new camera to take underwater photos. Has anyone try that? I don't know how the water will affect the exposure times, and everything. I' seen a picture by Justin Quinnell (http://www.pinholephotography.org/) called "Duck and foot" made with a drink can camera so I believe it is possible. I'll appreciate any help. I'll begin my first attempt soon. I'll tell you later about the results. Bye. Pedro.
