I am working with 16bit (Tiff) greyscale Heightmaps, images that displace geometry to create terrains.
When I want to adjust the images I do it in one of several applications that return the Heightmaps with an altogether different range of levels (value of blacks and whites). However I have no way of matching the levels of the updated image to the original except to eyeball it using Levels. This is time consuming and hard to get right.
I tried changing the images to RGB and color matching them, which is kind of what I want to do, but it leaves me with stepping (similar to an 8bit image) because the range it is trying to match is so subtle I think.
Does anyone know how to better use Levels to perfectly match (greyscale) images, or have another approach that might work?
