Blue / Green Screen - The ins and outs of Chromakey
Lot23 Studio, 23 Minnie St, Eden Tce, Auckland
6pm for a 6.30pm Start

From Weta Workshop to the nightly weather, Chromakeying has been the primary VFX tool in moving image since the 1930's. Despite this long history, Chromakeying remains a tenuous proposal, being a common cause of expensive post-production blowouts.

This seemingly simple technique of creating transparency by removing
Green or Blue, requires careful consideration of many variables to ensure a
successful trouble free chromakeying outcome.

Presented by DOP / Compositor - Sam Tozer - working with Chromakey since 2001 he's made all the mistakes so you don't have to!
