RE: Ware/Malde-Ziatype-DOP palladium,was RE: "New" Paper for Pt/Pd (and other iron processes, too)
Thanks Loris, that was the information I was looking for. I tend to prefer the more red tones, but I was attracted to the independence of humidity that the ziatype claims, since I live in such a dry climate and my humidification method has been anything but consistent. Looks like I'll be building a better humidifying box in the near future...
