Films other than Tmax but with no silver iodide included
can also show color; TriX, PanF+ and perhaps most or
all other panchromatic emulsions.
Perhaps sensitizers would be a better word; ones which
have color from the start or take on color through
processing. The color sensitizers are intimately
associated with the silver perhaps even
atom for atom.
In a word and according to Kodak, if film has color after
fixing then the fixing is not complete. Some of that sensitizer
now with color is hanging on to some silver halides yet not
removed. Silver iodide is a most insoluble halide. Most
using the iodized films recommend twice the fix time
and mention much reduced fixer capacity. Dan
