The densitometer reports the density of the colors in an image —how
many pixels of each color are in a given sample area. Densitometer

balance the color.
You can also mark a specific measuring point for the densitometer; for
details, see Setting the Densitometer Measuring

the exact spot where you've positioned the mouse pointer in the prescan

result from any changes you make.
