[gdal-dev] gdal_translate produces tif with different colors as original

[Marius Jigmond]

I noticed you're using ArcMap for visualizing the results. Did you check what histogram/gamma stretch gets applied by default when you load the layer? I run into this issue often as results from GDAL operations appear much worse when loaded into ArcMap compared to originals. When I turn off stretching, both histogram/gamma, results are nearly identical to original.
