I'm clipping a raster to a polygon using extract by mask (Arc 10.5). This produces a very skewed result. White washed image. I've tried using raster clip, but the "use input features for clipping geometry" option is grayed out so that I can't check it meaning I'm not getting the result I want. Some details: when I enable DRA the image looks much better. But I need to be able to view it properly without clicking enable DRA.

Any insight as to why the clipping geometry option is grayed out would be great. I thought it might be a memory issue but I have deleted a lot of data and still no change. Prior to the clip the image is a landsat 8 16 bit image with compression type LZ77. After the extract by mask the image becomes compression type LZW. The image that worked properly was compression type none, but when I export the data and select compression type none the image somehow becomes 32 bit.

I've had issues with this when the two were in different projections. Make sure that both the raster and the polygon are in identical datum/projections.
