I have three questions about histogram in Camera Raw:
1) Sometimes I dont see any overexposed or underexposed areas on the histogram, but I can see it on the image whith shadow and highlight clipping function turned on. I am confused - is the particular area overexposed when the highlight clipping fuction shows it on the image or is it overexposed when histogram shows it?
2) Sometimes I dont see any shadow clipping on the image, but histogram shows it and it usually disappears only when I partially desaturate the image.
So there are obviously differences between clipping display on the image and the histogram. What are these differences? Sometimes I dont know what should I trust.
It seems the clipping display on the image shows when individual channels are clipped and the histogram shows only overal clipping. Am I right?
3) The third question is - is it a problem when only individual channel (color) have reached its max or min values? Or should I be concerned only
when all channels (the overall luminance of pixels) are clipped?
