Since I shoot RAW, I can "batch" process several hundred images for WB, exposure, etc in a short time, perhaps 30-60 minutes.
I do an initial rating as I go along, then the final rating process takes about 30 minutes.
Finally, when I get the "5 star" images to locally process, each image can take from 2 to 10 minutes, depending on the complexity.
However, if there is a killer image I can spend hours on it, and like others, end up going back to an earlier version. Just like painting, where do you stop??
Sorry, long answer to complex question.
