Response to Does the color of the PMK stain make a difference?

Ed, Since you plan to publish your results, I would suggest that you borrow (if you don't have) a good color analyzer and measure the RGB or CYM values with and without the pyro stain. I would suggest using three negatives, with light, neutral and dark gray (gray card, plus and minus 2 stops, no other image) with a neutral gray processed in normal non-staining developer as the control. This will give reasonably quantitative data on the shift in color, and some indication in shift in hardness of prints on VC paper. Of course, if you enjoy this sort of thing you could expand the testing considerably, but I think you would rather make photos.
