In his article on Unblinking Eye , Sandy King points out that depending on the color of the stain, we can expect to see different results when printing on Silver papers, both Variable Contrast and Graded.
..."Brown stain blocks green light more effectively than green stain, and for that reason there is much less shouldering in the highlights with Pyrocat HD than with PMK. The result is that prints made with Pyrocat-HD negatives on VC papers will have more contrast in the highlights than prints made with PMK negatives, but there will less compensating effect."
When enlarging Pyrocat HD negatives onto Variable Contrast Silver papers, is the compensating effect basically lost ? - or is there still enough effect to merit the use of a staining developer anyhow ? (I hope the answer is yes, and I am aware of the other advantages: smoother grain, enhanced local contrast, etc).
