Lighting: Simple setup. 1 HDRI and 1 Directional light
A big thing I am focusing on is breaking up the lighting. In this case, I used a few VDB's of clouds to cast shadows on the land. This is something that is often overlooked.
I am a compositor by trait so I used Nuke to assemble the image (Everything can be done in PS as well). I rendered fewer passes than I normally would. Redshift (Beauty, Depth, Occlusion, reflection). Something I find helpful which you rarely see is the raw render. Here it is:
From there is where it all comes together.Adding fog, grading, slight zdefocus, overall sharpening. and more fog! The final look came organically as I wasn't using a reference so it was mainly all freestyling. Hope that helps!
