Guys, you are learning the complete alternative process if you study making gum bichromate, Pt/Pd, VDB and etc, but you are not learning silver gelatin, the most important process of them all as it has been kept secret and is now vanishing! I consider classes without some sort of silver gelatin to be incomplete. Using Liquid Light or other such products is like having the instructor hand you premade VDB or Pt/Pd solutions with no information on what is in there!
