A client of ours is having trouble with some raster tiles in ArcMap. The goal is to make the images look natural (without bright contrast). They gave me a sample, and I was able to reduce contrast with the following workflow:
Go into each of your loaded raster images, right-click, Properties, Symbology tab. Under Stretch, change the drop-down to None, and unselect Apply Gamma Stretch. Then it should look normal.
They tried this, and got it to work on partial tiles, but not entire ones. Is there any better solution? Attached is a tile sample.
