Pictures taken in Lake Tahoe, CA. The second is my son (3 years ago) having fun in the frigid lake water.

Two excellent photos. However the first shows the red problem with the canoe/kayak on the left end. The red appears to be over saturated and some detail is lost.

Thanks, Cal. This exercise is actually bringing up something strange. This canoe picture below was taken right before the one I posted first. Comparing the EXIF data I see that I made some changes to the camera settings between the two shots. On the first shot (above), there was no gain control, contrast=low and saturation = normal. The shot below, gain control was low gain up, contrast=high and saturation=high. Even though saturation was set to high, the image seem less saturated and I can see more details on the red canoe. I also noticed that the ISO and shutter speed were different between the two shots. The shot below has a higher ISO and faster shutter speed than the photo above.

Could be post processing or you can get strange color shifts in the red spectrum when converting from Adobe RGB to sRGB for web publishing.

The thing is, I haven't PP'ed these images in terms of saturation/exposure. I only changed camera settings prior to taking the shots and cropped them in Picasa.

I have also noticed that a faster shutter speed and/or larger f-stop will result in less saturation and more details.
