Hi and welcome.

For a flat surface you would use a normal to give the impression of
depth. Try bumps.
If you have a photograph that you want to use. You could use it as a
heightfield. Which would turn it into an actual 3D object. Where the
light colours are high and the dark colours are deep.

Here is an approach on such a material. Properly scaled it should do the job.

You may try something like :
normals{crackle -1 scale Your_Scale}

The -1 is to make it so that the normally high points become pits.
