Image Sampler modification

A warm hello to you folks!
I’m really new at this grasshopper thing, and trying to figure out a definition with the image sampler.
So i made a 3D photo with the google camera app

and on the picture there are a lot of cobblestones, based on the colour alertness of them i would like to give them a 3D shape- make them stand out as a form.

Can anyone help me on where or how should i start? :slight_smile:

Thanks a bunch!

I think you might be looking to increase the contrast in the image using either a shadow and highlights filter in Photoshop first or by some other means. Here’s an example. Try that and see if it works better for what you’re attempting with the image sampler.
