Suppose we have a sunset photo and we turn off the highlights reconstruction iop:
I understand that the magenta cast in blown highlights is the result of saturated sensor cells for all R- G- B- channels in combination with white balance. Let’s turn the white balance iop off to get a neutral color in this area and also decrease exposure to avoid clipping:
As far as I know, the sensor cells for all channels should be saturated for the white area (the sun), which should result in maximum R- G- B- values in the whole photo. But if we measure the RGB values, we can see that the R and G values for the yellow area (with unsaturated B values) are greater than the R and G values of the sun. How is this possible?
