In a few days, I'll be making RGB pictures, yet I don't know how to callibrate them, except by comparing with a RGB picture of a white reference with the same adjustments.
I read it would be good to use different exposure and gain for each channel so I get a similar histogram peak in all of them. Even if I use the same parameters in all channels, I should still balance them to correct sensibility variations of the camera, and even atmosphere effect near the horizont. So, after so many variables, is there some process or rule of thumb to put all of that again near their true colors?
English is not my first language.
