For those of you that use a pyro developer,

Is it normal for the D-Max on a pyro-developed piece of film to be noticably less than that with 'normal' developer on the same type of film? (I don't have a densitometer, so I can't give you a reading, but it is very noticeable, side by side.)

When I look at the leader of film done in, say, Diafine, then at the leader done in WD2D+, the density is noticeably less with the pyro film. I've noticed that I have to print pyro negs with higher contrast than non-pyro, but I understand that is somewhat understandable, because pyro is a little softer-acting that a normal developer. (?)

Negatives developed in a staining Pyro developer will tend to look thinner than negatives developed in a standard developer. Densitometers don't work real well with Pyro negs anyway, as the stain is very complex. The best way to tell if a Pyro neg is exposed/developed correctly is to make a print on you standard contrast printing paper.
