When a JPEG or TIFF file is edited in ACR, are the edits destructive when you click the "Done" button, permanently changing the file? Or is the edit info saved in sidecar files like with edited RAW files, not affecting the original file?
If I reopen a previously edited JPEG file in ACR, will the adjustment settings be the same as where I left off, allowing me to change those edits, like a crop or HSL adjustment? Thanks.
First: There is a Camera RAW Forum.

Second: It should be fairly simple to test your hypotheses.
And on my station at least it appears the data is stored in the file and not as a sidecar-file.
