I am setting up my traditional film darkroom, initially concentrating on black and white. And need some information relating to Kodak Wratten Darkroom Safelight Filters. I want to be able to use the correct filter for the related printing paper, and need to know the details for a specific filter. Which is Kodak Number 0B, and Filter Colour Amber Yellow. I need to know which Kodak materials this Filter can be used for. I have located technical information for the other Kodak Wratten Safelight Filters that I have, but not this one. I know there are traditional darkroom gurus out there that can help me with this.
