Number of grey tones possible with Platinum prints
March 8, 2012
Historically there has always been strong comparisons made between platinum/palladium and silver gelatin prints. Regarding tonal range and optical sharpness the general consensus is that platinum/palladium prints have more evenly distributed mid tones and a more delicate response in the highlight values. Silver prints are able to produce a greater reflection density Dmax i.e depth of black and also appear sharper than platinum/palladium prints.
Recently I heard one expert state that platinum prints have twice as many grey tones than silver prints. I like doing comparisons in the darkroom, it would be interesting to learn how one would go about testing this claim. Penn may have had this on his mind to in the late 1980’s…..
