Some good examples. I used to use picasa to check myself but found that I would end up really over doing an image. Like you said, it works well with certain images. From my experience, shots with high contrast run thru picasa are a toss up. Might look better, might not. But, for a no nonsense, easy to use free program, you can't beat it. I downloaded the program and ran a few sunset shots thru it and this is the result for this one particular image. I downsized the images to 900 pixels wide and Saved for Web to make them easy to post here. They, like most any other images, look so much better larger. First image is before the Picasa wash.
