Let's say, for sake of argument and curiosity, that you photography bookworms had to choose only one of the photography books you own and donate/sell/whatever the rest. Which one would you keep? Limit your answer to only one book please. I'll go first. 'The Negative' - Basic Photo 2. Fifth printing, 1971. Why? Well, it has become my go to photographic Bible to refresh myself from time to time and this edition really helped me to make my Weston Master IV light meter more a part of my process rather than just a cool old light meter. I love this book and it is the last one I would part with. How about you guys?
