I have some footage that contains some 'blown out' flourescent lights in it. The rest looks pretty good, but I would like to adjust only the lights. Would I have to duplicate the layer and then mask the lights, or is there a way to isolate it on the main comp and work with it there? Thanks.
Create a pre-comp with a duplicate of the footage, adjust it's Contrast using Levels, Unmutliply it using Shift Channels set to Luminance. Then you can use that pre-comp as an adjustment layer and apply whatever effects you fancy to correct your blown out stuff. likewise, you could then easily use the pre-comp as a matte.
Great help as always Mylenium. Thanks so much.
