I don't know how we got on this path. Once upon about 30 years ago, I was first chair oboist and "principal photographer" for the Norfolk symphony. It was in the musician's union contract, would you believe? I had a good shot of the conductor that the board wanted to posterize and use on posters. I had a recipe for the necessary developer but no hydroquinone, so I tried ascorbic acid and it worked, but not without expectations. I had access to a lot of books on every conceivable subject and I did know how to read. My Daddy taught me at the age of 5.
