cool. another question is on exposure times. I’m not confident in my abilities to determine this, so i figured i would try to make as many constants as possible (lol) my camera has an f/8.8 lens and an iso setting for either 75 or 3000. On a bright sunny day, probably at the beach, how long should I expose my plates? I plan on doing a self portrait with someone else behind the camera ( i wouldn’t dare ask someone to be my guinea pig at this point) and I have two shots at it (because I only have two plates) I managed to make a mobile darkroom (yay!) out of a camping shower, some blackout curtains and a floor dryer fan (for optimal vapor removal) with a custom “low” setting. now all i need is the sodium thiosulfate….
