[Peter Blackburn]

Hi Alberto
 
Yes, you are exactly right. Depending on exposure and such, manipulations with ammonia baths (dilute and straight), brushes, spray bottles, hoses, vegetable sprayers, even your fingers, are all possible techniques with casein. The same can be true with gum, too, but casein is more robust and can handle far greater aggressive handling.

Casein is like heaven for the "hands on" artist. Most of the time I just do straight development—actually I like the "panning method" of development for both gum and casein. It's a real rush watching the image appear out of the murk and mire.
