I was trying to get a turntable animation done for the first time.  
I openend the NOMAD-symbol in the upper left-hand corner and changed the “Turntable Speed”.  
I clicked outside of this NOMAD-box to get back to my viewport, and all of a sudden, the whole appearence of my viewport had changed: the background was pitch-black and the model was hardly to see (black and white).  
 → see screenshot

1. what happened?

2. how can I get back to a normal NOMAD-life?

I found it:  
In the upper right hand corner, in the Settings-menu:  
 → Debug  
 → I mistakenly clicked on “Heightmap” (so “Heightmap” was activated)  
✅

How can the “Heightmap” be used?  
What is it good for?

one use for height maps that I tend to use is to make alphas for brushes.

For example sculpt a rocky surface, screen grab/render the height map, add to a sculpt brush alpha with grab/drag option then use it to proliferate a larger surface with texture.
