Raster symbology doesn't display unless stretch is applied.

Discussion created by mark909 on Nov 11, 2013

I've noticed this on a couple of rasters recently but I'll give you my latest as an example.

I've been processing a DEM. When a new DEM is created using Stretched symbology the raster appears in only one colour unless I apply a stretch in which case it symbolises as I would expect it to.

Any idea why this is? I can always do some screen shots if I'm not making sense!
