  Dave Laronde Keylight Recipe

  Posted by Tracy Hern on June 9, 2009 at 2:29 am

  Hi Dave;

  I came across a recipe for noise reduction that includes this

  “Fool with the lower layer’s Keylight settings until it looks like the subject looks fine, but is over a grayish, washed-out chroma key background. It’ll take some doing, but you will have gotten it to the point where Keylight’s spill suppressor is working. That’s good, because the Keylight spill suppressor works darned well.”

  I can’t figure out how to use keylight to get to this point as as soon as I put the eyedropper on the bacground I lose the ability to get the grayish washed out chroma key background?

  Do you mean play with black and white points until background is grayish?

  Thanks for your contributions. I imagine that you have done it all in your years and I for one am grateful to be recipient of so much in-the-trenches guidance!

  Tracy,

  I think Dave means to look at the alpha channel. Toggle the button at the bottom of the comp panel to change from RGB view to Alpha only view. The black areas are transparent, white are opaque, and grey are semitransparent. You want as little grey as possible.
