I have a GeoTiff that changes colour when I zoom into it. It looks like the red channel goes missing.
I'm am not using any gamma strect or fancy display scales (in fact I have tried playing with the stretch options a bit and am seeing no improvements).
The change seems to happen between scales of 1:8000 and 1:6000.
I am doing a raster QA task so it's important I see what it really looks like.
I get the same problem in QGIS or Arc does anyone know of what might be causing this problem?
