I have had so many people asking me about spectral sensitization that I have scanned the Kodak catalog from 1971, Catalog #46 listing their recommended dyes.

They are no longer available from Kodak but represent a cross section of usable dyes for emulsion work.

Thanks, PE; that's going to be quite helpful. Its interesting that a few of the dyes in the "other" section are used as either indicators or biological marker dyes. Im interested that Congo Red is on the list; that stuff is quite inexpensive.

I have said before that Erythrosine is not the worlds best sensitzing dye, but it is inexpensive. I think that you will find that dyes on the 'other' list are not very good either, but that they do work.

Best of luck.
