So at work ive been doing some photo correction for our parts inventory (kill me now, please) and my typical routine is: Open Image(s), Levels/Curves, Bright/Cont., Crop, Save. I know i know, i can batch them but the person taking the pictures doesn know sh\*t and every pic has diff. light/placement values. Which gives me different results with every pic. _angry fist_. Anyways, thats besides the point.

The Point: The hotkey for levels is ctrl-L/cmd-L (duh :b). But what is ctrl+alt+L ? I did it on accident and its almost like auto levels but not quite. I think it finds the highest value of dark/lights from the looks of the graph, but what exactly is it doing? I know this might be a simple nub question but i cant seem to find anything about it, even in the keyboard shortcuts options within photoshop(?)

Just curious :ponder:
