Dusk and dawn are magical times of day! Combine an interesting background with an interesting well-lit subject at exactly the right moment… Boom!!! Home Run! A photograph that everyone takes a second look at. A shot to be proud of!

dusk flash photography

40mm lens, ISO 400, F7.1 x ½ sec., WB 6000K. WB set for speedlights. Underpass goes very warm sky goes deep blue. Very little ambient light on subject allows a long exposure.

This dusk image and article demonstrate the following techniques:

  1. Dragging the Shutter
  2. Multiple Speedlights
  3. Line of Sight Communication
  4. Different Color Temperatures of Multiple Light Sources in One Photograph

Fifteen to 45 minutes before the sun rises or after the sun sets is usually the very best time to be shooting. The sky is rich and dark—but not black—and the night lighting is visible.

Secrets to Creating a Successful Photograph

  • Choose a visually interesting location that is well-lit at night.
  • Select a subject that is relevant to your background.
  • Scout and shoot tests prior to the photo session to determine the best time and camera angles.
  • Experiment with various length lenses and find out the color of the natural ambient light (skylight and man-made).

How to Light a Subject at Dusk

Multiple speedlights are preferable, but even one speedlight used correctly will be dramatic!

Three speedlights were used for this photograph: a main light, fill light, and a kicker or accent light.

Lighting Setup for the Above Photo

The Main Light (B) was placed into an Umbrella Softbox nine feet from the subject. The Umbrella Softbox was raised slightly above the subject’s head and angled down a little. The main light’s job is to light most of the subject. This light should make the subject appear three dimensional—difficult to achieve with a single on-camera speedlight. The speedlight was set to ½ power.

Fill-light (A) is an on-camera speedlight with a medium sized diffuser attached to soften the flash. The fill-light’s job is to fill or lighten dark shadows with just the right amount of light. The speedlight was set to 1/8 power.

Kicker Light (C) was placed just outside of the camera’s frame. It is sitting on the concrete wall with the plastic mini stand attached. (Now you know what that thing is for!) A small diffuser was attached to soften the harsh flash a little. This light created the highlight on the right side of the subject’s face and hat. The speedlight was set to ¼ power.

No radio slaves were needed for this photo. “Line of Sight Communication”—the system that is built into modern speedlights—made all three speedlights fire simultaneously. It works flawlessly when used correctly. You must make sure that the Slave Speedlights’ sensors are aimed at the Master Speedlight’s sensor. The Master Speedlight is on the camera and the Slave Speedlights are off the camera. The Speedlight’s adjustable head makes this system of lighting possible! Point the light at the subject and rotate the sensors toward each other.

Rotate the head of the speedlight toward the subject. Sensors must see each other without obstructions

Note! It is critical that any modifier attached to the speedlight not obstruct the sensor.

Shoot in Manual Mode

The speedlights and camera were set to manual mode. Manual mode gives the photographer maximum control—very important under rapidly changing lighting conditions. The camera was mounted on a tripod since we were shooting at a very slow shutter speed.

The photographic term “Dragging the Shutter” is a technique that combines a slow shutter speed with a burst of flash (1/500 second or faster) from the speedlight. The slow shutter exposes the background and the nearly instantaneous flash exposes the subject.

To lighten the background, slow the shutter speed. To darken the background, increase the shutter speed. To lighten the subject, increase the speedlight’s power or move the lights closer to the subject. To darken, do just the opposite.

Note! Once the speedlight lighting ratio is dialed in and the background exposure is calculated, it is easier to make overall exposure corrections by adjusting the ISO up or down in 1/3 stop increments.

Multiple colors of light in the same photograph should usually be avoided or corrected. Dusk and dawn take advantage of these color differences, offering the early bird or night owl photographer a rich, vibrant color palette to work with!
