Interview with Troy Sobotka - Part 2

This episode is the second part of my conversation with Troy Sobotka who is a Vancouver based lighting, rendering and all-round image creation person. You may know him as the designer of the Agx render transform. We dive further into the mechanisms of visual cognition and picture formation. He shares a vast knowledge and collection of reference material on this topic. See download link below for additional material.

In past years he has written an online blog called the Hitchhikers Guide to Digital Color. I would highly recommend people to read it.
