This was one of my favorite books when I was teaching photography, many years ago. I believe this book is a condensation of the wonderful Time Life Photography books from the early 1970s. The last edition I'm familiar with was the 2004 printing. Don't know which edition # it was. The only difference I noted from the older books was that mostly they updated the types of camera equipment used. Lots of good information on photography, lighting, film, printing etc. Well illustrated too! I don't know if the newer editions deal with digital, but I assume they would. If you're mostly into film, which I guess you would be on this site, check out one of the older ones that cost less.
