I love macro photography for many of the same reasons you stated. I live in what easily could be called a nature preserve. I love walking through the place with my camera (not a very good one) and trying to slowly get close to the insects, birds and whatever else I can creep up on. I'd like to get a better camera but I don't think that my old Konica/Minolta point& shoot is the weakest link. That would be my lack of knowledge and experience. Thanks for your article, that should help me a good deal.

Any suggestions on how I could improve my macro shots would be appreciated.
