Using the Densitometer Monitor
The EPSON Perfection 600 densitometer displays the
density of an image— how many pixels are in a given
area.
Densitometer readings are useful when you:
◗ Adjust contrast
◗ Change the tone curve
◗ Balance color
◗ Change resolution
The top row of the densitometer shows the red, green,
and blue values of the original image. The values in the
lower row show the values that result from changes
you make.
The pixel display area reflects pixel density (and color
saturation) at the exact point where the mouse pointer
is positioned on the prescan image area. As you move
the pointer to different positions on the image, you’ll
see the values shift.
Note:
The densitometer window
is informational only.
Values cannot be changed
from the densitometer.
