[QUOTE="WayneF, post: 524757, member: 12496"] I may be going too far, I usually do. :) But in the raw editor, here is the histogram of the first blue jpg. The dog is back lighted, and we can see that it is this rim of light that is overexposed, the rest is in shadow. In Adobe raw, hold the ALT key down while pressing the mouse on the Exposure slider, and then it shows only the clipped tones (for that Exposure setting). We already knew this time that it was the rim highlights that were clipped. [IMG]http://www.scantips.com/g2/histo1.jpg[/IMG] We know this blue image has white balance wrong, but we can see that in the histogram too, see how red is low, and blue is high? (in the histogram). This of course depends on the subject colors, but this subject has fairly neutral colors, and it is NOT neutral now. Red is too low. [IMG]http://www.scantips.com/g2/histo2.jpg[/IMG] So we adjust WB (here I clicked the WB tool on that white spot above the ears, hoping). This helps a lot, but of course, it shifts red much higher, where it should be (peaks are much more aligned, neutral, which is right for neutral colors, but which would be very wrong if it were a purple dog. :) ), but which is greater clipping. I reduced Exposure about 1.3 stops, and debated with myself that maybe 2 stops was better. But the advantage is that we can see, we can choose best result. [IMG]http://www.scantips.com/g2/histo3.jpg[/IMG] The rim highlights are still clipped, not much can be done about that now, but it's actually sort of like a feature, a special effect, not a real problem always. The spike at the right end of the histogram indicates the clipping, and again, holding ALT on the keyboard while pressing the mouse button on the Exposure slider then shows which pixels are clipped. Sometimes that's real good to know. [/QUOTE]
