    Re: Using a densitometer on a pyro developed negative

    Note that it's controversial whether split printing can give unique results if not applied locally, as per Phil Davis's article on it in Darkroom and Creative Camera Techniques.

    Re: Using a densitometer on a pyro developed negative

    What Steve seems to be doing is simply designing his negatives to be printed at a higher-contrast setting than "middle," i.e., like using a #3 to #5 filter. This is a really good approach in my estimation; I find many VC papers have muddy mid-tones in the mid-to-low contrast range.

    As for measuring effective density on a pyro neg: You need to measure at the same spectrum that your paper is sensitive to. IIRC, didn't Nicholas Lindan/Darkroom Automation have a densitometer designed specifically for dealing with pyro-developed negs? I don't know how active he or his company is anymore. Maybe someone does.

    EDIT: The main page for Darkroom Automation is here: http://www.darkroomautomation.com/da-main.htm and it still shows the enlarging meter/densitometer for pyro negs.

    Best,
