I've taken some instruction at a local community college, an introduction class of sorts, learning basics about film processing, printing, and a little about composition and so on. Pretty much an oral version of Henry Horenstein's 'Black and White Photography' handbook.

Ever since then it's been about seeking information, from books, and others. I've been blessed with knowing lots of really knowledgeable people, with possibly hundreds of years of experience between them, which has been invaluable to me. And, I don't ever intend to stop learning.

I believe some formal training is good, especially if there's room for a lot of soul searching and internal exploration.
