Auto features are exactly what i was looking for. You may use big button to auto adjust everything or use auto contrast / gamma / levels / sharpness etc... one by one.
Gives awesome results most of the time. Example photo results speak themselves. Gives crazy results only in not so usual visuals like graphs / calendars... (Since I like it so much I tried it on everything) But again, visuals like these can be auto adjusted partially.
You may try free version and see. Paid version uses much advanced algotihm.
Fast and helpful tool.
