RE: Van Dyke and Kallitype
Just for the record, I did not say that the Dmax of VDB sucks, only that I have never been able to get quite as much with it as with kallitype. However, if you set out to compare Dmax with the two it should be done with equal conditions, say single or double coating both on the same paper, same RH, etc.
Sandy and Loris,In practice, however, very few people make negatives with enough contrast for VDBI must be the exception. Right now I'm looking at two VDB prints on my office wall with excellent DMAX, midtones, and highlight gradation. Using TMAX 400 and PyroCat-HD making negatives for VDB is pretty easy. Just as an FYI these prints are partially gold toned and have a gold additive in the sensitizer. But to say that DMAX for VDB sucks doesn't match my experience. And I do double coat. Don Bryant
