Its been a while to starting study Pyro developers .I read Viewcamera article on pyro experts thoughts on technology and I just impressed.
If I am not wrong , film gelatin hardens with the reference of its illumination and this creates valley and mountains in film.
I had Edward Weston book and I had no idea about his use of Pyro. I read he has notebooks. Are they published ? And I learned he has a special Pyro ABC formula plus Amidol developer written in his notebooks. What was the color of his negatives ? Is there a scan at web or somewhere ?
Can you give me these formulas ? Which film and paper he was using ?
Do changing film change the stain color ?
Is his era gelatin formulation same with today ?
Thank you ,
