Getting detailed information about digital images (EXIF)

I’ve advertised my Nikon D200 for sale, and a buyer asked how many shutter actuations it had (less than 1900, barely used). But I was stymied at first in determining the answer to this basic question; the explanations I found on the web were vague and when I tried GraphicConverter v5.6.2 (one recommended solution), I could not locate the information at all.

So I turned to Phil Harvey’s ExifTool. It is a command line tool (like my own DiskTester and diglloydTools), but don’t be scared off by that. For detailed information and/or repeated use, a command line tool is much more useful than a GUI.
