First Renders

[B9Creations]

I'm using Alibre Design to create basic 3D model.  KeyShot seems pretty straight forward... But wondering how I could render dark/stark shadows to match the moon rock shadows?

TIA,

I've done a bit of space renderings.  Strong light sources look better.  Start by matching HDRIs to the backplates used.  Try adjusting the gamma and brightness.

Anyone suggest a good tutorial or tool for creating HDRIs?
