PAINTING WITH LIGHT INSUFFICIENT LIGHT OR LARGE AREA
Camera Exposure: Bulb “B” Mode JPEG: Large Fine ISO: 400 Aperture: f/8 (for more depth of field – f/11)
Shutter Speed: Shutter open until flash or flashlight sequence is completed Lens Stabilizer: On
Focus: Manual focus (if needed, use a flashlight to focus) Place camera on tripod and attach cable release
Flash: Manual “M” 1/1 (flash will be off camera)
Technique: With camera composed, focused, and pointed toward subject area, depress cable release and lock it in
“open” position. With flash in hand, quickly walk and manually flash an equal pattern around subject area (outside
camera’s angle of view). Ensure to flash parallel to the deck toward desired areas to be lit. Return to camera and
release the lock on cable release to take photo. Note: A flashlight can also be used to paint. The “painting with
light” technique, allows you to light and image a large area using a single electronic strobe light, a spotlight, or—in
some cases—even a good flashlight. To accomplish this, the photographer moves the light throughout the scene,
exposing one part at a time, while the camera lens and shutter remains open the entire time.
