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. 

Do you find that the amount of stain is not consistant?

What I mean is, it seems that, for the same type of film, some days (batches of film) the stain seems stronger than other days. Sometimes, there seems to be little stain at all.

It also seems to vary by film. I just did some Fuji Acros last night, and I'm not sure I see any stain at all.
