Not much of a picture guy personally but I see your point.
Edit: I have spent a decent amount of time organizing books and comic books and that was a pretty even split between GUI and Terminal. GUI to get them in a state that I could bulk rename/move into appropriate directory with the Terminal. I assume it would be similar with pictures.
I spent last winter ripping all my DVDs, and I did a lot of the organizing, changing file names etc. in the terminal. Because I could automate the process even a little.
When doing TV shows, I could take the names of episodes from an online database, put those in a text file, use block edit mode and macros in Vim to format them the way I want, then use a bash command to iterate over the lines in a file and rename them all. Hell I’d probably still be at it if I had to rename that many files manually, even using copy/paste.
