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.

Use scrollbars to adjust contrast and brightness of source images.    Also contrast and 
brightness of the resulting image can be adjusted.

larger than original monochrome images. 

•  Original source images for Color Mixing shall be of 2560 × 1920 pixels or smaller 

size.  

•  When one or both of source images are monochrome, it will take a longer 

processing time than where both images have different single colors.
