A virtual stand-in swims underwater

The finished composite.

	Background - B roll from aquarium
	Actor filmed with swimming motions against blue screen.
	When the matte was keyed, the discovery was made that the pedistal interfered unacceptably with full body visibility, Rather than reshoot the sequence with a wire rig, the decision was made to create a CG stand-in.
	A virtual actor was created and manually match positioned to follow the motions of the bluescreened actor. Since the final lighting was blue, a greenscreen was used and the figure was lit for the composite.
