About the Presenter: Chris Shaw

Chris is a product manager for communication products used by emergency services. He has a formal education in software and product engineering and he helped productize the first-ever mobile phones.

He loves sci-fi and fantasy and uses his spare time to create 3D assets for his digital art, which he then uses as a basis for 2D airbrush artworks and also as an inspiration for characters and world-building in his writing.

Focusing mainly on photorealism, Chris takes great interest in pushing tools and techniques to see what's possible. He works mainly with Blender, Daz Studio, and Photoshop to create his assets and scenes, but loves to broaden his knowledge of all 3D assets and tools that aid the production of 3D art and cinematography.

Chris believes in sharing knowledge to better ourselves, collaborating to make life easier, and having as much fun and exercise as circumstances allow.

On some 3D sites, Chris also goes by the name Abrushant.
