Photoshop auto levels?

When I run the "auto levels" command in Photoshop usually it appears to make numerous changes to my photo automatically. Is there any way to find out the specifics of what it did?

David Earls   Easiest way is to create a new adjustment layer, selecting the layer as a Levels layer. When the Levels dialog box comes up, examine the Red, Green, and Blue levels first, then click AUTO, and the sliders will move as if you had simply selected Image/Adjustments/Auto Levels. You can see the adjustments just by selecting the Red, Green, and Blue channels again.

It's better, of course, to learn how to use the Levels and Curves controls on their own. Sometimes the Auto commands choose wisely; sometimes, not so wisely...

  Hello Alan;

First; drop the "auto levels."
You might find in many of my posts, I am NOT an advocate of (auto) anything! LOL..and just for the reasons of what you are asking.

There is almost no control whatsoever in "auto"

While David says "sometimes, not so wisely..." I'll go out on a limb and say rarey does it choose right. I never use it.
