Auto Adjust Photo tries to give a solution for the automatic color
correction of photos. This means setting the contrast, color balance,
saturation and gamma levels of the image by analization.

This can be a solution for those kind of users who are not able to manage
and correct images with complicated graphical softwares, or just simply
don't intend to spend a lot of time with manually correcting the images
one-by-one.
