I found these videos helpful and filled with little tidbits of valuable platinum printing info. I believe this photographer lives in Toronto, might try to contact him, ask if he gives lessons. I believe I can learn to do this process on my own but to have an instructor, a mentor is always important, valuable, and speeds up the learning curve. Mr. Hauser looks to be a master at platinum and you always want to learn from the best.
