In this episode I chat to Kevin Shaw. He is a well know colorist and educator in our industry.
He has also been a key figure in setting up and promoting the Colorist Society, which is the topic of our following episode. In this episode however we discuss telecines. Kevin started grading 10 years before I did, at a time when color grading was either telecine or film lab based. We discuss various stages that the industry has gone through since then, all the way up to the present.We discuss:

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.

On this episode I must apologize in advance for having way too much fun.
My guest is Jason Iversen he is a Visual Effects Technical Supervisor who has worked at Digital Domain, Rythm and Hues and now is at Weta in New Zealand.
We have known each other since high school and worked together many years ago in South Africa.
He was the co-founder of the Odforce.net chat forum. And he has worked on more block buster films than I’ve had blocked noses.
We talk about visual effects, color pipelines and rendering techniques through the ages and discuss where things are heading with the merging of Weta with Unity games.We discuss:

In this episode, I'll be talking to Thatcher Freeman. He's a California-based colorist and software engineer. For his day job, he's an actual AI specialist. He's made great contributions to the color grading and software coding communities. He's also a filmmaker, so I wanted to talk to him to find out what makes him tick.
We discuss:
- Thatcher's background in film making.
- The difficulties on finding resources on color theory.
- Current industry trends.
- A colorist's value.
- The combination of art and technology.
- Freelance pressures.
- Subtle vs Pushed graded.
- Things that break the signal.
- Personal taste in films and watching as a professional.
- Thatcher's DCTL library.
- Advice for DCTL coding.
