SETUP
A light bulb socket was firmly mounted to a table over a black backdrop.
A pellet gun was mounted to a V support to keep the end of the barrel
48 inches from the bulb. A sound trigger was placed in close to pick up
the sound of the gun going off. The sound trigger was connected to the input of a delay module who's output in turn was connected to an electronic
cable release. By adjusting the delay to correspond with the pellet
piercing the lit light bulb I captured it just starting to explode with
its filaments still lit .
Note: The exposure was 1/15 sec. at
F16. A reflective ambient meter reading was taken of the lit bulb for
the burning filament portion of the exposure while a flash meter was used
to adjust the flash output to match the ambient F16 reading. This shot
could not have been achieved using open flash technique as the lit bulbs
would have totally washed out the image.
