    Hey All – first posting here so please be gentle… I am a complete AE neophyte and am looking for guidance so I can pitch this to a real AE person if this is feasible…

    I want to shoot a James Bond Thunderball-type opening – with a couple of girls and a wiener dog swimming in a pool (the film is a documentary about competitive dachshunds). I just want the girls/dogs outlines – not their features (since they are being kind enough to be nekkid for me lol). Is there a way to capture mask out pool/background and just keep the silhouettes? I was assuming the motion tracking tool would be the way to go?

    Any guidance would be greatly appreciated.

    Shane

    There is a filter called “Threshold” which looks at the brightness of a pixel and makes it either black or white. If the girls and dog(s) are darker than the pool background then the Threshold filter can quickly turn them into black silhouettes.
