I am avidly reading John Shaw's Closeups in Nature and consider it must-read material for anyone! I am reading through, learning a lot of information, and deciding what items I plan to buy next to supplement my current equipment (and it doesn't have to break the bank!). I want to learn more about nature photography as well, so I can learn about how to best telephoto, extend the telephoto, compose, etc. I saw he has two books on the subject so I'm not sure which one would be best to get. The two titles are: Focus on Nature, 1991 Nature Photographer's Complete Guide to Professional Field Techniques, 1984 Please advise... Ross
