> “this is no different than focus stacking (assuming my subjects hold still - THAT will be a miracle)”

In almost every case where I’ve tried, fully automatic focus stacking fails to give satisfactory results. I don’t do interiors, and outdoors there’s almost always some ghosting. If, say, a reed moves in the photo that’s supposed to be in better focus, the algorithm may take parts of the reed from another photo with inferior focus distance but less subject movement. You end up having two versions of the reed. With outdoor shots I usually get better results by manual layer masking.

Not that Photoshop’s Auto-Blend Layers / Focus stack is totally useless. In places where subject movement is not an issue the results are very good, and the ghosted parts can be restored by manual layer masking, cloning, content-aware fill (either as part of the Fill command or as a mode of the Spot healing brush), or or whatever.

Regards, Antero
