Mike Moats runs macro photography boot camps around the country.
He has dedicated his photography exclusively to macro work and makes a full-time income from his macro work.
He sells his artistic nature photographs and teaches macro photographic techniques through workshops and eBooks.
Mike does a lot of compositions that are not super close-up macros, technically not a true 1:1 magnification. That is not meant as a negative comment. He just doesn't limit his photography to larger than life images.
I am particularly fascinated with his great use of lighting and compostions with his photography of leaves and flowers. His artistic use of software to enhance his photos is remarkable.
