Potassium Dichromate - Uses - Photography
Potassium dichromate has few major applications, as the sodium salt is dominant industrially. The main use is as a precursor to potassium chrome alum, used in leather tanning. Like other chromium(VI) compounds (chromium trioxide, sodium dichromate), potassium dichromate has been used to prepare "chromic acid" for cleaning glassware and etching materials. Because of safety concerns associated with hexavalent chromium, this practice has b… WebGum Bichromate Prints.

WebAug 15, 2007 · SUMMARY. Most mammals have dichromatic colour vision based on two different types of cones: a short-wavelength-sensitive cone and a long-wavelength-sensitive cone. Comparing the signal from two cone types gives rise to a one-dimensional chromatic space when brightness is excluded. The so-called `neutral point'refers to the wavelength … Webpearance match between the two eyes of a unilateral dichromat as eigen-colors. In 1995, Vienot et al.
