Worth a look for a discussion of 13 images and their histograms -

Thanks for that pointer. I agree with most of their comments, with the
possible exception of:

http://www.juzaphoto.com/shared_file...gram/exp-2.jpg

which I would not describe as "a completely overexposed photo" - depending
on what was in the sky area. Perhaps there's some blue sky there, but it
looks more like white cloud to me. It would have been useful to show it a
stop less exposed, but with the gamma increased to restore the grass and
trees.

Just looking at most of these pictures is enough to tell the experienced
photographer whether or not they are correctly exposed - there's no need
to view the histogram to confirm what your eyes tell you.

Cheers,
