Will be good to have Auto contrast/brightness image effect, for making low contrast images more colorful.
ImageMagick have those options for this:

-auto-level
-normalize
-contrast-stretch
-linear-stretch

@Murz,

I was playing around with these options, but I have no idea how to correctly use the contrast- & linear-stretch ones. Should the black & white points be configurable in the effect? I do not see a possibility to configure them automatically. What do you suggest?
