What happened to Pinakryptol?
Pinakryptol dye was/is a desensitizing agent that allowed
film to be inspection developed under an OA(?) safelight. I know it comes in green, yellow and white - with the yellow and white preferred these days. Does anybody use it for developing sheet film by inspection? -- Nicholas O. Lindan, Cleveland, Ohio Consulting Engineer: Electronics; Informatics; Photonics. |

What happened to Pinakryptol?
I would love to find some. I do 4x5's from my pinhole camera by
inspection. I have the dark green safelight, and take a quick peek about 2/3 of the time through the standard time/temperature value. Works fine. At those low light levels, it is very hard for me to judge contrast/level of development, but I have had good results. |

What happened to Pinakryptol?
I have quite a lot :-) really !
but then it's economics and depends where in the world you are. I bought the entire stocks of Photochemicals from a UK chemical supplier a few years ago - for next to nothing. They were bought up and ceased trading the following year. So loads od Pinacryptol Yellow, dilute and highly concentrated / powder. So if your in Europe no problem, it would be cheap. Ian "Paul W.
