Here’s four examples of Photolemur’s default picture correction, before is on the lefthand side, the after is on the right.
This page may take a while to load, there are eight pictures being downloaded.
The differances for me were easier to see on a computer monitor.
The Photolemur examples are at their Photolemur website, here’s some of my own.
