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

Subject: Re: [pinhole-discussion] ortho film
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
