ArcMap keeps redrawing my 4 band false colour image in standard 3 colour bands. As you can see below I have my 4 band data set to auto display as (4,1,2 - infrared, red, green). When I bring in an image layer it displays as it should and the layer properties clearly show my settings are working.
If however, I pan around and zoom in the image reverts to a 3 band image - the image difference is shown in the attached image. When I go back into image properties it shows that ArcMap has automatically changed my bands to (1,2,3 - R,G,B) - even though my customization menu still shows my desired settings as (4,1,2 - iR, R, G).
Any idea why ArcMap is doing this?
