This was an interesting one to shoot. The client wanted this handset to be in water, somewhat matching a previous image with a blue background.
I set up the handset near the top of a blue lego box filled with water. Light was punched through from behind, and then I used a cloth to squeeze water out, for the 'torrential rain'. It took several versions of that shot, blended together for the final effect. Lastly, the screen, which was delivered as a GIF image was blended and added, along with the green 'on' light, the rod holding the radio was removed and I added foreground water and ripples.
