Plan your lighting on a real 3D head. Move the lights around the floorplan and watch them fall on the head in real time, with real cast shadows across the nose and cheeks. Set the backdrop, the skin tone and each light's angle, height and colour, then read the positions off the shoot sheet and build it for real.
A planning aid rendered in real-time 3D. The subject is a neutral reference head; light direction, shape and cast shadows read true so you can plan a setup before you shoot. Angles are from the camera axis: 0° straight on, 90° side, 180° behind. Needs an internet connection the first time it loads the 3D head.
