Hi Ben, theese two things are rigth. Developing of ortho works under red-light, 15 Watt bulb, 2 meters from tray, is normally. Developing cyanotype works directly by the sunlight (only UV-Rays are working). When you expose the cyanotype by sunligth, you see the coated paper get darken green_blue_grey. When the highlights are grey, its enough sun, you get inhouse in a room without daylight, dunk the paper 5 times for 3 minutes in fresh water- your work is finish when dry by the air. Do it, it's great. Regards, ingo ----- Original Message ----- From: [email protected] To: pinhole-discussion@p at ???????

Hello Everybody I was wondering if anyone could help me. I would like to know more about ortho film. I have heard it can be developed in a tray under a safe light. Also I have heard there are alternative processes called canotypes that can be developed in sunlight. I would appreciate some information about them Cheers Ben
