I don’t know how useful this will be, but I used the search phrase “creating a greyscale depthmap in photoshop” on youtube and got a bunch of hits, mainly geared towards CNC routing, many of which touch on file setup. If you have time you could repeat that search and look further. From what I understand at this point, we get to skip most of the painful stuff they show(ie tool paths, g-code setup, etc.)!
here are a couple that could be good for getting the gears turning, using photoshop’s 3D features to render/preview.
(edit- note that we won’t have to convert our images to “3d” per se, but we could preview what the results might be when we engrave)
