  Keylight – news to CS3 – alpha bias

  Posted by Graham Quince on January 28, 2008 at 9:21 am

  Hi guys

  Does anyone have a good primer on how to use the new version of Keylight. I found with the older version I quite often used to adjust the value slider of the Alpha bias, but now it’s a colour value and I’m not sure how to use it correctly.

  Any pointers?
