"Cameras don't make pictures, photographers do."Got this book on Tuesday and have since implemented my morning/ afternoon one hour reading sessions. It is full of useful advice on how to improve your photography skills, and it is made with us hiking, backpacking and mountaineering folks in mind. Thus if you're serious about photography, and before you invest more money into new fancy camera gear, first spend the ~ $17 for Remote Exposure: A Guide to Hiking and Climbing Photography.
In the meanwhile, I am working on an article about the Sony NEX-5 and Panasonic Lumix GF2, which hopefully is ready next week. So after you've read the book, you can read about which lightweight camera you might want to get =)
