Hasta La Motion!

The camera is looking down at the talent at a 45 degree angle in some partially blown out water, and I am adding cgi behind coming out of the water, and need to disturb the water somehow so it appears more photoreal.

I want to generate a ripple or even disturbance in the water.

Heres the challenge, the water is already moving, and parts of it are blown out where I want to add the cgi, so if I do create a ripple, how can you see it over the blown out water below and even if you see through the water below, its already moving at a slow pace.

Or can I bypass the ripple and disturbance all together if I make the water appear more blown out, it may work that way?

Any ideas?

Thanks.
