Bob, Go to the File tab, then down to the
File Info. This should pop up a window that has several listings, description, camera
data, origin, history, etc. Clicking on history you should be able to see each
step that has been applied to the file. It will however, only be there if you
have it selected to save it from the preferences. On the general tab, there is
a check box for history log. You can select text and meta, or both with
session, concise and detail.

I've seen this while working on an image, but I'm totally unaware of it
being saved. How does one access this historical record of changes?
Wow, I missed this
thread. Judy the file can have information attached to it
as well that will tell you all the changes. If one was intent on making
things up through digital manipulation it would be hard to absolutely prove
it but here come the "If it smells like a... and walks like a... " .
PS will give you a list of actions taken toward the file and I don't mean PS
actions from the action palette but any retouch, opening, closing, etc.
There was in fact, on one list that I participate, a desire to share the
file info so that other could see what you did to make the image.
