3d carve help needed

[WillAdams (William Adams (Carbide 3D))]

That file is a pixel image which uses light/dark to represent light/dark, not height/depth.

You will need a file which uses light/dark to represent height/depth, or to use a tool which is able to reinterpret a representational image as an explicit mapping to dimension.

3d carving of a photograph

Hello, would anyone happen to know what is the best way to 3d carve an image from a photograph (i.e. portrait, album cover e.t.c.)? I’m planning to do these on to 18mm thick oak at roughly 400mm square but just would like some advice on tool settings and also cutter size choice which would be best to achieve these. I’m not looking for a particularly deep cut, say around 3mm, just enough to get the effect. Thankyou in advance.

and other discussions here for some examples.
