I have a height map that I would like to convert to gray-scale. The problem is I have a custom palette or gradient that I wish to follow and I am not a professional, so I don't really know how.
The applications I have tried to use are GIMP and Photoshop.
Here is the map i wish to convert to gray-scale.
And here is the scale used for this map, where the most left is low and the most right is high.
And here is how I want to convert the height map so the lower points are white and higher points are black.
You can try in Photoshop using a gradient map, but it looks like too many of the colours on the scale have similar brightness values for this to be very effective. You best bet will probably be to tweak whatever software package generated the map in the first place so it produces a greyscale image the way you want it. – cybernetic.nomad – 2018-12-29T15:04:29.933
