any shortcut keys for adjusting brightness and contrast?

Use Auto Levels: ctrl-shift-L . If your time per image is limited, then more often than not, this will improve an image quickly. —

Control-M. This brings up the Curves command.

Curves can do everything that Brightness/contrast can do and a whole lot more besides. When newbies first get Photoshop, they tend to use Brightness/Contrast, but this is not a good idea. The
Brightness/Contrast command is a "linear" command; each time you use it, it degrades the quality of your image by clipping detail from the hilight and/or shadow areas of the image.

Curves can do everything Brightness/Contrast can do, but Curves is "nonlinear;" it does not degrade your image by clipping detail. This is why Curves has a keyboard shortcut and Brightness/Contrast does not. Once oyu learn Curves, you will never use Brightness/Contrast again.

Personally I use Shadow/Highlight for a quick&dirty adjustment. PS remembers the last used settings so it’s consistent across multiple images.

You can tie any key combo you want to this or most other PS commands via Edit/Keyboard Shortcuts in CS/CS2.

I would said color informations will be lost when you do any adjustment and that is degrading image’s quality. It is a matter of threshold.

A matter of error in rounding, more accurately.

However, this is different from clipping. Clipping occurs when light-colored pixels are changed to pure white, or dark-colored pixels are changed to black. The Color Balance command works by moving the entire histogram of the image left or right, which clips image detail from hilights and/or shadows. This is in addition to, and much more severe than, information lost through rounding.

Photoshop also remembers Curves (and all the other commands under the Image->Adjust menu) across multiple images. To apply the same adjustment, such as the same Curves command, again, you hold down the ALT key on the keyboard while you choose the command. Alt-Control-M (Mac: Option-Command-M) applies the same Curves command as the last time you used it, for example.

Well, I’ll be darned – something I didn’t know.
Thanks, Tacit.

omg the master of curves!
I am not sure how I first learned that but it’s very handy for adjusting several similar

so many good things to find out about PS
