Art Morris has been touting the above to get perfect exposure. He claims people underexpose when using the cameras histograms. I wonder if anyone uses rawdigger in the field. I can see using it if you can shoot, move the file to a pc, look at the file in rawdigger, make adjustments in exposure, and shoot again. I guess you could always take a well exposed image and then another one at +1 exposure and later compare before processing. I digress. I want to know if anyone uses it and opinions.
