Why list the EV adjustment of the photos? The effective EV is apparent from the capture settings and listing how much you adjusted the photo based on your camera's meter isn't that useful. Each camera meter has its own quirks and it seems strange to include such a subjective setting.
On the other hand, I dig that you include lens and focal length. Both are nice to know when viewing photos.
Yeah...that was what I was going for but the parent comment has a point, one which I did t really think about until I started collecting photos and noticing that some of the photos didn't match expected EV...I had thought that the EV reflected what the camera registered, no matter what mode I was in...but of course, it only measures compensation, which will be wrong if the photo is taken and the EV doesn't match the EC. And since I've just confused myself trying to explain this I doubt it's clear to the average reader.
It would be pretty easy to generate histiograms with Imagemagick...that is probably more useful
