I shot this in my backyard, using two lights in beauty dishes on either side of her to 'catch' the water, and a light in a softbox on a c-stand to light her face & body. Two friends were throwing water at her, and I kept the camera in the same location so I could composite different splashes together to get the final result that I wanted. Also had a couple pieces of plexiglass on the ground for a reflection and to make the water 'bounce' more than just on the pool deck.
