I have recently upgraded from compact (Nikon S4) photography to full SLR (Canon EOS 400D) and all the features (ISO, shutter times, aperture, etc) are a little daunting at first, but having read this book from cover to cover I am now more confident with what to do in all the different conditions I might face. Let's be honest - I'm not exactly going to remember all of the information in the book at each photo opportunity, and I'm not likely to carry this with me all the time, but the information and technique advise, plus full colour photography examples for each subject covered really do lend a hand to the enthusiastic beginner and to those who what to take their photography to a more 'professional finish' level. The majority of detail in the book suggests ways to get the photo right first time, without having to then spend hours with editing software, and it was this advise that I found really useful as I am also a beginner in that arena too, and learning that is twice as hard as just getting a good photo in the first place! I mean what could give more joy that a 'perfect' shot without any post photo editing required?
