I set up an exercise to use flash to concentrate light into a spot. I had planned this shot and technique to include in my assignment, and took several shots to achieve what I wanted. The subject was placed on black velvet which will absorb the light. I wrapped a piece of black card around the flash to direct the light. I discovered that using the flash to light the subject from the side created the most 3D effect. The shutter speed and and amount of background light were fairly critical.

In the first few pictures I took, the snoot was too wide so the subject sat in a pool of light. By narrowing the diameter of the snoot, the light can be directed. I discovered it was easier to mount the flash on a tripod. By increasing the shutter speed, the camera sees the light for a shorter length of time enabling partial illumination to be achieved.
