First, just a point about histograms. From my experience with teaching clients and creating images with other Pros, those who understand exposure best, check their histograms much more often than those who poorly understand exposure.
So those who need it the least, use it the most. It must be a valuable tool!
Everyone should take advantage of that great teaching, learning and confirmation tool.
The "Don" had just jumped off the Hooptie Deux in the sweet water of Tampa Bay.
With unabsorbed sunscreen on his face and air still in his waders, he immediately starts creating images and checking his histogram.
