I came across the following in a book dated 1948:
"Desensitize the plates by one minute's immersion in 1:2000 Pinacryptol yellow. Alternatively proceed in darkness"
It then goes on describe tray processing of the plates.
I took this to mean I can desensitize film and process in daylight, or not desensitize and process in darkness. Otherwise, why would I desensitize the film if I have to process in darkness anyway. Am I reading this correctly? What is Pinacryptol yellow? Does it mean to process in blue light and the Pinacryptol yellow blocks it?
Eric.
