Features, rules, opportunities
Today we invite you to talk a little about backlighting. With this effect, the light source is located close to the back of the subject. Typically, this kind of light is used to emphasize the depth of the shot and the perspective thanks to the shadows cast by the objects. It can be both natural and artificial.
Backlight in a landscape
Backlighting is often used when shooting landscapes, as when the sun is directly in front of the camera, the landscape often gives the impression of something even more impressive. Because of the bizarre shape of the clouds, sunlight makes the sky so interesting that it itself can become the main subject of photography and dominate the frame.
When using this kind of light in a landscape, keep in mind that when the sun is high enough, it illuminates the top of the opaque objects.
As the sun tilts towards the horizon, the light at the top of the objects decreases and a light halo forms around the edges. This halo contrasts with the softer light falling on the subject from the front and makes it stand out from the surrounding background. For example, when water is backlit, bright reflections appear on each crest of a ripple or an individual wave.
Portrait in nature
When creating a portrait outdoors, using the sun as a light source, it is necessary that the light falls at a low angle. In other words, it is best to shoot either in the early morning or late in the evening when the sun is near the horizon. If the model has long flowing hair and it is windy outside, you need to position her so that the wind blows towards the sun.
In order to emphasize the light outline that appears on the subject's hair when shooting in backlight, it is necessary to find a dark background. If you can find a background that is even slightly darker than the subject, this will be enough for the desired contrast. Trees with green leaves and shadows, a dark wall, or the shadowy side of a building can be used as a background.
To evenly distribute the light through the hair, you need to place the model in the right place. The sun should be directly behind your subject or slightly off-center.
Also, in order to avoid glare, care must be taken that the sun's rays do not enter the lens. In such situations, the hood helps a lot. However, lens flare can be another special technique for enhancing the effect of backlighting in a photograph.
Backlight in the studio
In portraits, contrast is very important - the difference between sharpness and blur. And backlight is just the technique that can give it. That being said, the light coming from behind can create a lighter outline around the edges of the subject's hair - a great contrast between the head and the background, and generally contribute to a clean, angelic look.
Using backlighting, you can make the effect of a “glowing silhouette” - leave the subject itself dark, and get a light outline around it. To obtain such an effect, it is desirable that the light source does not fall into the frame, so as not to "blind" the camera. This is achieved by narrowing the field of the frame, which is provided by increasing the focal length lens... However, the "blind spot" can be a special artistic device.
Remember that backlighting is designed to separate the subject from the background and can add drama to the picture. For example, in theater lighting, backlighting is used to make the actors stand out and give the stage a three-dimensionality.
