This might not happen for all the color channels in each photo--it might just happen for one of them, as it did in the example of this post. Notice how the blue channel extends all the way to the right, but the red and green channels don't? That's because blue has a lot of highlights in this photo. I didn't want to overexpose these highlights, so I stopped increasing the exposure as soon as the blue channel got as far to the right as possible, without actually going off the histogram. @Pete – If you’re shooting in RAW, then the goal for a good exposure is to get the histogram of one of the color channels as far to the right as possible, without actually overexposing that channel.

Do you just want to keep each color away from the edges ? And how did you expose for a specific color....blue in this case ?

Assuming your camera does have an RGB histogram and you see that one of the colors channels is different than the rest (such as the green one in your sample above) is there anything that can be adjusted in-camera to correct it or is this the sort of thing you'd correct in post processing? Also I noticed you're shooting RAW -- at least the top image capture shows the camera was set to RAW mode :). Steve,
