How do I read pyro negs on a color densitometer (mine is a Kodak, a rebranded X-Rite) ? Is the pyro reading OK on a color densitometer using the Vis mode, or should I read the blue channel of the RGB mode ? How does it work with different stain colors, e.g. the yellow-green of PMK, or the brown of some pyrocatechin developers ?
Thank you for your answers.
