Over the past month I have developed over 150 negatives in pyrocat. One thing that I have noticed from reading about pyro is that many use it for alt processes. As I understand it, the stain responds differently to UV wavelengths over the visible (mostly blue) wavelengths used in enlarging. Apparently many people use pyrocat negs for dual purpose silver and platinum/palladium. My question is how do non-pyro negatives work with alt processes? For example, will a D76 1:1 negative respond to UV and Blue wavelengths equally?
