Camera is set up on a tripod (to ensure all images will be registered the same way).
Approximately a dozen images are made, with each image being a single fire of
a handheld flash (the Canon 550EX), fitted with a piece of tinfoil to better
snoot and control the coverage of the light, the flash itself moved to a different
location for each shot. Afterwards, from the twelve shots made, a number of them
(in this case 6)are selected to work together, and in Photoshop, different parts
from each image are used to construct the final image....*here*.
