Retired educator - taught mathematics in high school, went back to graduate school, worked in research labs, and finally went back and taught computer science...
One post processing I forgot to mention is that I put all my photos through Oscar's Jpeg Thumb Maker to reduce the size. Monitors display at 72 dpi so having excess size does not help the picture. this photo was originally over 6.5M I cut down the resolution to 1/2 of the original and 1/5 of the file size.
