Ground Imagery Over Exposed

I have been experiencing this problem for quite some time and I cannot seem to find a way to resolve it. Hopefully someone will have a suggestion. When I import Ground Imagery, the contrast is often way too intense as if the image is over exposed or a contrast and brightness filter were applied improperly. I checked the image in Photoshop and the brightest areas are well below 255.255.255 RGB white. I would almost say that some shader is parcing the images wrong for the viewport. Has anyone else experienced this issue? Anyone found a way around it?</

That's a negative. The image only appears to have the 3 color channels and not a 4th. My imagery is defaulting to a band mapping type of RGB. As a test to see what would happen, I switched to Gray and set band #1: red as the type. I get a grayscale image for the aerial as expected, but the white are completely blow out as before. Again, it is as if AIM is applying a contrast and brightness filter to the image.

Did you find any solution to this problem? I am having the same situation, and I don't know what to do...

My solution has been to adjust the overall brightness for the environment from 1.5 to 1.2 (Visual Effects in 2015, Light Intensity). Otherwise, you can type in a gamma correction value located in the Raster Tab for the Ground Imagery (Data Sources).
