I have a two-dimensional, multicoloured image such as a corporate logo, and I wish to modify it to create the illusion that it is an image rendered in paint or raised ink. That is, I want the medium to appear to be three-dimensional.
I have played around with various techniques but have so far failed to produce a result of great quality. I achieved some semblance of the effect by applying the emboss effect, altering the contrast and brightness, changing white to alpha, then reapplying the original image underneath. However, the emboss effect extends out further than the edge of the image, and my technique also applies black shadowing rather than darkening and brightening of the original colours. I essentially need something similar to the application of a normal map.
Has anyone had any success with a similar project?
