compositing water
I have some footage of a person under water in a very controlled circumstance (the person is lit, but the pool is a single key-able color not represented on the principle). I need to eliminate the key color effectively, without removing all of the water attributes. I get the keying concepts, and the color-correcting for color bounce from the key color, as well as composting the shot into the scene. I even have particle illusion to add bubbles, etc. for better integration. All of this will be color corrected for matching purposes.
That said, I would like to keep some of the original bubbles and ripples caused by the actor, however in keying the color out I’ve lost those details. Is there a way to create a plate of just the water bubbles and swirls (the reflections within them are the key color right now) as a grayscale clip that I could use to create an image plate and a displacement map? -

use a separate key, but dont key as tightly, preservign the details that you want. you could then use your subtract your principle key from this layer and use it as precomp for displacement or however else you wish

I am very well acquainted with rotoscoping.
If I rotoscope the water (impossible, by the way)I lose the smooth integration of the element, and still have to key out the color.Keying to a different color spread and masking out the unecessaries with a feathered mask has been my choice.

that sounds like a good choice
