Select color for source images. Check Color and select R, G or B button.
Select a mixing mode in the mixing selection box.
• ADD: Add A and B source images. Use this when two images are of different single
colors.
• AVG: Average of A and B source images is used. Use this when one or both of source
images are monochrome.
• MAX: Compare intensity of each pixel of source A and B images and use larger data for
resulting composite image. When A and B are of different color, it results in the same
image as when using ADD. When one or both of source images are monochrome, it will
result in a clearer contrast than when using AVG.
The following picture is an example where source A is SE and B is BSE image and they
are mixed with green and red colors.
