This software has a tool that makes a lithopane from a photo. 4 file types can be imported. .bmp, .jpg, .jpeg, .png
Quality of the photo makes a difference, some worked fine and others took some touch up. Photo editing software that shows the histogram is the secret sauce.
Cura has a few adjustments that can change the extrusion ... height, direction, slicing accuracy etc.
It's helpful to be able to test the settings by printing a few models.
A question for Geoff
Blender import ? ... what is the path to importing a .png, or .jpg
