Histogram Brain
When using the Brain in Histogram do you have to measure all of the the colors in the drop down box. Or is just one enough to get the measurements for capturing.

Re: Histogram Brain
Hi,
no need to measure all of them - just pick the most relevant one and measure using that.
For instance, if you are capturing a nebula that is dominated by red, you may choose red as the filter as you are then measuring for the most important thing in your scene. However you might choose blue if you were targetting the nebulosity around M45.
Blue will often give a much higher exposure value than red or green, since the light pollution background is usually relatively weak in blue light.
thanks,
Robin
