Local Bleach Reduction on Color Prints

[epraus]

Hello All!

I am working with a color negative with a pin hole which obviously is printing as a black spot. Does anyone out there have any suggestions how to reduce the spot to white so that it can be spotted? I tried using Potassium Ferricyanide (the time tested B&W method) to no avail.:confused:

Kodak lists a set of bleaches for each color dye somewhere. At least they used to. I have forgotten what they were or where they were, but if I can find them, I'll post them.

You can use regular chlorine bleach, but last time I tried it was very difficult to control. You should spot it on the negative as greg said.

Umm, if you have a black spot on the print, then the negative has nothing to bleach guys. So, you either dye the negative with a spotting dye, or you bleach the dark spot on the print.

Kodak's suggestion was to spot the pinhole in the negative with an opaque dye, rendering the spot white, and then to touch up the print with appropriate dyes.

If it's a pinhole size spot like that caused by a dust mote it can be retouched by carefully abrading the non-emulsion side of the negative. If something larger, opaque will work. I generally like to have someone else do this for me as I always seem to make more of a mess of it than the pros.
