Brightness or RGB

[Derek G]

Scrolling through my cameras settings this morning , I noticed the histogram setting has two, either { brightness or RGB } and i cant find any relevance to this in my manual, what setting do i want?

Hi Derek, I would use the four channel histogram. The red channel overexposes easily, especially if the photo has a lot of red in it, such as a red flower. When you notice either the brightness or the red channel climbing the wall on the right side of the histogram you should use the exposure control (EV for Nikon cameras) and begin to under expose until it does not climb up the right side of the histogram.

I agree with Joe, use the RGB setting, or RGBL if possible. (where L = luminance aka brightness)

Which camera is it?
