This was an experiment trying different light setups for photorealism in 3D portraits and this is the result.
It is not high resolution, it was rendered in Blender 2.92 using Cycles (OptiX) with 32 samples.
In this video at the end of the description (speed up to 2 minutes because real-time was 20 minutes)
every single light setup took roughly 10 seconds (around 3 of them 20 seconds like the red light setup while
waiting for the denoiser to smooth out the skin). I will continue using these setups for my future artwork both
mixing 3D and 2D.
