Cheat your way to faster depth of field! A C4d/Redshift tutorial from Microcosm medical Animation.
In this free tutorial I show you a sneaky way I've discovered to hugely speed up background blur / DOF and help separate your foreground and background elements to increase image readability. Update note: This tutorial was recorded before the introduction of RS Noise Reduction, and therefore doesn't mention it. Combine both techniques for even faster results ! :)
