I have checked the manual, FAQ, and tried a search under "Levels".
The Fuji-S2 starts to pick up blue noise in shadows ( beginning to be a problem around 4-5 stops under exposed). This is from some tests I have seen on-line by people who are far better able to do this type of testing than I am. There is also some red noise (less and beginning at about the same EV) but, for my work, this is FAR less objectionable.
I have noticed this when doing drastic enlargements and have been controling it by moving the left blue level slider to the right to chop/force to solid color that section and then try to move the middle slider back to the original mid point to avoid an overall color shift.
Is there a way to de-couple the levels sliders so you can move one end without the center one moving?
If not:
If I move the left slider 10 units right, is a 5 unit left the proper correction to move the center slider back to it’s original position? (Those numbers were used to make the math easy.)
OR
Is this best handled in Curves?
Thank you.
