Thanks TimeSpirit. That’s embarrassing–obviously I didn’t search the docs well enough :eek:
EDIT
Unfortunately the above link doesn’t help me at all with my issue.
EDIT 2
For what it’s worth–for anyone looking for a solution, I seem to have gotten decent results by saving the terrain (in 3DEM) to 32-bit floating binary (matrix). (Saving as 16-bit integer seems to not be interpreted correctly by Photoshop). Then, using Photoshop, change the mode to 16-bit/channel, by way of using the method “Equalize Histogram”–that seems to be the trick.
