Photo Adjustments - Color & Light

 [Note: I finally resolved my technical difficulties with Adobe Photoshop. The short story is my video card is insufficient for OpenGL Drawing so I had to disable this function (all I needed to do was un-check a box, who knew?). I have been having fun playing around in Photoshop this week and re-learning what I had learned on GIMP]

 I really like the ease with which a picture can be manipulated to look completely different than the original. However, I did not see much difference when I attempted Color Cast Correction using Levels Color Channels. Did anyone else see much change when they 'played' with this feature?
