I am quite new to Grasshopper, and I have tried to follow the directions of this tutorial to generate a topographic model from an image.
For some reason, in my file, it won’t allow me to make the colours of the image “negative” - which, to be honest, I don’t know what that even means. Furthermore, it seems that my points from my surface divide branches out into a tree, but that doesn’t happen in the original tutorial.
I’ve tried to replicate the articles script exactly, even making a file with the same dimensions, but it doesn’t seem to make any difference. Any help will be appreciated!

EDIT: Sorry, I uploaded the wrong grasshopper-file! Should be the correct one now.
