And you really did not respond to my "what possible advantage" question.

So is it your position that when using the Levels command, you always use an ajustment layer, unless there is a distinct advantage in not doing so? I work the other way 'round. I will use it if it's an advantage.

In my specific case, I'm producing thousands and thousands of PDFs weekly. I don't want to preserve layers, type, or anything else. I have the original, unedited raw files, and the finsihed versions (PDF). I do not need the intermediate steps that got me to PDF, not no way, not no how. There is NO, let me be very clear, NO advantage, for what I do to keeping intermediary files. In fact, if you want to talk about advantages, it is FAR AND AWAY more work for me to have a semi-final version of these files that contain these extraneous layers.

The advantages for me, my product, and my business are frankly, too numerous to mention.

Some images that I produce do, however need to have adjustment layers. They are images I know I may have to go back to at some point in time and either adjust, or will want to preserve them for the sake of "safety".

But the conculsion that I should use, for example, adjustment layers instead of destructive edits is simply a false conclusion. It's a Frank Lloyd Wright thing - form follows function.

Michael,

I would use an adjustment layer whether or not I was going to save the work file with layers;

Personal preference. I might too. But then agian, with history states and snapshots, if it's not required in the final file, I most likely wouldn't.

I may want to go back and tweak it after putting in the background of the Folies Bergère.

I laughed. Thanks. I know - there are some images like that. My real point in bringing it up was, there are some "generally accepted practices" which are not always applicable. In the OP's case, if they're just creating a flattened JPG, who cares if it's an sdjustment layer?

We don't need to beat this to death, I am only continuing to reply so as to assure clarity. I feel that I've probably done that (and beyond) <grin>.
