Shot that for a local ad campaign. Experimented with compositing and hand drawing (the sharks are drawings). The model has been photographed from the front and from the back to get that reflection. The water has been photographed using a fish tank with some blue-gelled lights.
The lighting on the model is with two lights: a blue-filtered softbox in front of her and an orange-gelled umbrella behind her.
That`s Stunning
I'm glad you like it.
