  • How to change someone’s water reflection

    Posted by Stamatios Dimitrakopoulos on April 13, 2008 at 6:46 pm

    I wanted to make a quick scene where a hit and run driver is haunted by the image of the person they killed.

    In one scene I have an over-the-shoulder shot of the person looking into a pond at his own reflection and then I’d like it to change into the reflection of the victim.

    At first I tried to use masks to cut a hole in the top layer to reveal the person underneath and then I changed the opacity so that it blends in better.

    Is there a better way to achieve this effect through AE or filming it differently?

    The original shot has no reflection at all, so I’d need to first put in the original persons reflection in the water and then have it change.

    Thanks to anyone who can help !

    Hi,

    It sounds like a job for blending modes.

    If you have the shots of your reflection images masked or keyed out or even shot against black, you should be able to layer them over the water and change the blending mode to something like “Overlay” or “Screen” or “Lighten” and get a much better effect. You might also want to add a displacement map effect to the reflected image, using the water as the displacement map layer. If these don’t give you the look you want, try all the others ones. Blending modes are great for creating realistic reflections.

    Then all you have to do is dissolve between the first person and the second and you have your effect.

    Hope this helps,

    Lars
