Good question. I only use ACR as the Develop module in LrC which remembers the edit history in its database (AKA catalog). I think you would want to send it to Ps as a smart object but I don’t know how and if that works as smoothly as it should. LrC and Ps are supposed to be two peas in a pod. I have not explored that route..

The ACR filter in PS looks a lot like the LR (classic) Develop module, but it does NOT have a history list. You can “undo” any number of steps but there is no history list.

I never noticed that because I have never used ACR in PS except to verify the claim that it is identical to Lr.

Lr is all about organization and saving large numbers of photos without making copies of the image data within the camera generated files. Hence, when you edit a file rather than store the result after each operation it immediately saves your input for the operation (keystrokes, mouse movements, screen touches or, in my case, Wacom strokes). When you want to print, post or publish the final output by Export it reproduces all operation in full resolution before applying the desired color gambit and any compression such as jpg.

In Ps (My speculation. I’ve never verified this.) ACR apparently saves the changes locally until you save as the results in a file type of your choosing. In the Ps case the history does not serve any purpose. I suppose it saves edits in a compressed form as a sidecar file if you choose to save as raw for reuse in another Adobe application.

The advantages to the database approach of storing the camera file separate from the change history in a database catalog include in reducing storage size because you never need to make copies of the humongous camera files and you can go back and change an operation in say ten years without recalling and redoing the entire process. It also permit selective copying edits between selected photos and virtual copies in catalog. The disadvantage is the Library module and its import dialog is a clumsy burden for some. I don’t see a remedy to that.

Ps is still much better in selective edits but is a pixel by pixel editor and storing reversible edits is double humongous in size. I like the database and count on it so I start in LrC go to Ps primarily for power line removal and return psd files to LrC for safe keeping. But to each his own.

Most of the time, I have no room to move back and forth, as it would involve stepping off a cliff, into water, into traffic, through a wall, into people...and so on.

Thank you for addressing "lens correction" . I just researched my photo editor, ON1 2024.1, and it has automatic lens correction. On1 adjusts my Tamron & Canon lens. Although I can go in and make any level changes manually. I have never tried or I guess given it any thought about correction. "I just Assumed"

good as any
