I imagine photoshop has had it for a long time. I do raw photography very sparingly and barely know photoshop. Literally one of the first thing I wanted to do was batch operations on a set of photos in which the lighting and camera setting were exactly the same. A quick Google revealed it is frequently used.

Photoshop hasn't even existed for a long time yet.

Well, not in geological terms, but I would say that 30 years for a piece of software is a quite long time.
