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.
