    I just started with densitometry of my pyrocat negs and I am uncertain what gamma to aim at for visual and blue light. I intend to do silver printing only and use a Wratten 47b filter with my Macbeth TD 502 to do the blue readings.

    Any thoughts?

    Gamma or density range? Middle of the road development, I would say a gamma of 0.62. For silver printing I would want a DR of 1.00 to 1.1. to be printed on grade two paper, of course a better approach would be to test the exposure scale of your chosen paper and adjust the film density range to that paper....good luck.

    Hi Jorge,

    "Gamma or density range" Rigth know I am aiming for average gradients (G^_) but I am willing to adopt whatever method works best. I would prefer to keep things independent from a special paper as I am using several depending on the tone and response to toning I want. OTOH, who knows what will be left on the shelfs in a few years from now?

    My main problem is the the marked difference between visual- and blue-densities. Should I optimize to a G^_ of 0,62 for the blue or rather visual density? For graded Paper I should watch for the blue density I guess but my main papers are VC.

    best

    If you are planning to use pyrocat then use the blue channel results. In reality, while I understand your desire not to get stuck on one paper, if I was using VC paper, I would then print one of the stained step tablets on it to test paper response.
