Hi folks,
Something that might be useful along these lines. I had started playing with all of the different settings in different conditions at first I did not write all of that down, I figured it was lost information. That was until I pulled up some of the photos is a program I have used for years to view image files call Vueprint. It somehow reads the information from the picture and displays the shutter speed, F and the DPI, making it a lot easier to track this information. Its a light but very useful little program. You point it to a directory and can step through each photo by hitting the spacebar. It can do quite a bit of editing functions and can do slideshows.
