Hello Rich,
Thanks for your input.
The owner of the stone is very shy about revealing what sort of message is possibly engraved (or chiselled) in this stone. I don't know much about it.
I've tried the 3 color tools you mentioned without any great result (they worked technically but nothing was 'exposed' better).
I'll play with the bump map, as it appears interesting. Similar to the 3D scans I did before on the stone.
Offnuts: I tried 3D laser scanning (I'm a lot more familiar with this technology than image-editing) and even with 6 million points spaced at 0.01mm -0.1mm average, did not see much. The pits in the stone create a lot of noise and the 3D model looks like the usual orange peel so common with good quality scanners (they pick up too much detail).
And these point clouds are fairly large to work with (3D meshing et al.)
So I tried the optical approach. But as you mention, I may be able to see more shadows by applying what you said.
My photos were taken on a sunny day, in the back of a SUV.
Thanks.
Rich,
I tried bump mapping quickly, using the same image as map, and this gave me a fairly decent result.
I'm not a 'power-user'-far from it.
So I'll do as you said, use a B/W copy of the image as map.
The 'help' is pretty good on this topic.
I am impressed with this filter.
Thanks.
