So I have a few georeferenced .tif files that I need to add to a raster mosaic, however the problem is that some of these are 8 bit unsigned TIFFs while others are 1 bit unsigned. After adding all the TIFFs into the mosaic, the 1 bit TIFFs display as a black square, while the 8 bit TIFFs display normally. Is there a way to have all TIFFs display properly regardless of bit depth? I sort of got it working by changing the image properties to display as a stretched values rather than RGB composite, but this makes all the colour TIFFs black and white which is not ideal. Any ideas?
