I'm starting to research purchasing a new digital camera that can can take good general pics ( vacation, etc. ) and good aquatic pics. I don't really have much of a photography background, point-and-shoots being my only experience. I hope to educate myself with as much info from this site and would appreciate any advice from those who are obviously far more experienced and talented than I. I have decades of experience in the hobby and would like to give back to the hobby in new ways such as developing talks with power point presentations.
