For several years now I have been following the work of a Louisana photographer, Ronnie Gaubert. In my opinion he sets a standard in macrophotography for all of us to aspire to.
You can find his galleries on the pBase photo sharing site: here is his “Nature of Louisiana”. At latest count, his galleries presenting the wildlife and nature scenes of Louisiana have scored a little over 5 million page views (more than 10 times mine on pBase!).
He has been very willing to share his techniques with others, e.g. in the DPReview discussion forums. I am sure this is another reason why he has so many admirers.

This is one of his images, uplifted with permission from his gallery “IT’S A SMALL WORLD by Ronnie Gaubert” .
