Almost done with his Mexico daybooks, i swear, i can't finish it, because it makes me stop what i'm doing (reading) or have planned and go shoot. It's both funny and somewhat insightful, not on his technique, but on what makes a great photographer... practice, patience, and devoted. He was so poor, his wife sent him money, while he had his eldest son in Mexico, while being with his mistress (Tina).

Suffice it to say, his devotion paid off.

I cannot stress how many times he mentions making his best print to date.
He was always excited, and even through mistakes, he clearly learned, and devoted himself to a better negative next time. he made many rookie mistakes, ones that we can only appreciate from doing ourselves. His knowledge was learned a posteriori (learned through experience).
