Terry Danks Posted May 24, 2019 Share Posted May 24, 2019 In astro imaging, I have a need to . . . 1/ Define or select a specific point on the background sky and 2/ Adjust the RGB values at that point so that they are equal, i.e., the sky is neutral with no color caste. I have found how to have the values of R, G and B for a point under the mouse displayed but no way to adjust the 3 individual channels to have them equalized. Is this possible?
