NB. During capture never use Gamma adjustment ! Leave Gamma by default.
Automatic White-Balance is not the good choise for Mars : and for any subject with a main strong color.
( You have a slider to reduce the effect )
Try to use " Gain RGB" method.
But be careful to do not over-expose a channel.
Example : if a channel has too much gain, reduce others channel's gain !
I never touch Gama or Saturation. And leave Sharpness at minimum. These are the settings for all sessions:
However, I cant remember where the Gamma setting came from - should this be 1.0 or 0.0?
I do adjust Contrast to get the histogram starting at a good early left position (with a small gap to the axis) then I adjust RGB Gain to get the lines as close as possible to the right in the histogram.
I started another thread in the beginners imaging section on how to use the histogram. Its interesting that I don't get many replies - the replies I have received have been helpful though. I am thinking use of the histogram is not a well understood topic.
Where I am now at is given the camera has two green pixels per red and blue I am thinking to start off with R and B balanced and G less than R and B. Then adjust according to eye.
