I've came across an issue with rasters. I had 8bit raster in FGDB as an input, used eg. Extract by Mask and the result (also in FGDB) and it become 16bit raster. I see no reason for this conversion.
I am not aware about any setting in Environment options or Advanced ArcMap Settings.
Could anybody give me an advice how to set up ArcGIS not to do that? I know about Copy Raster tool, but it requires to make another copy of raster dataset.
My ArcGIS for Desktop version is 10.2.1
