to put it another way, i can change the amount of unsharp mask on an image i processed a year ago, without having to redo *anything* else i did. all of the retouching, white balance, etc. remain the same (unless i choose to adjust those too).

But you can't do that once the image has been exported.

nospam
nonsense, of course i can, and have.

Eric Stevens
But not to the exported image,

nospam
so what?

the fact is i can change anything without needing to redo the entire process.

floyd said the entire process would need to be redone. he's wrong.

not with the original sidecar file.

nospam
there is no sidecar file.

A documented demonstration would support your position.

any book on lightroom documents exactly what i've been saying.
