Low-key lighting is a technique frequently used for portrait images. It enables you to emphasize shadows to create a chiaroscuro effect. Different from high-key lighting, low-key lighting has greater contrast between the dark and light areas of the image with a majority of the scene in shadow. When you want to apply it in your photography, you can learn more about the definition, the method to take low-key lighting portraits with your camera, as well as the post-processing method from the article.
Before introducing low-key lighting in photography, you should understand what is the shadow tone. Black and white photography is about shading, black, and white light-sensitive materials recorded in black, white, and gray images. In black-and-white photography, the expression of contrast is one of the important features. Tone includes high tone, medium tone, and low tone, which include low tone lighting.
Low-key lighting is a way of photography that can express a dramatic effect. It is mostly used to show the expression of moody and emotional attitudes. It always evokes a sense of fatalism that hits the soul and is mostly used in satirical films to highlight the emotional dynamics of the characters.
|Low-Key Lighting||High-Key Lighting|
|Composition||Low-key lighting with dark gray to black shade levels accounts for the majority of the image, with a small amount of white acting as a contrast to the shade.||High-key lighting is mainly bright light tones, most of the image is bright tones, mainly white, even if there is a small amount of black, but also very little, only a minimum part of an image.|
|Lighting||Low-key lighting is mainly the use of part of the beam, and the background to produce contrast can be, to present the image of high contrast, while the need to properly reduce exposure compensation.||High-key lighting is commonly used in frontal light and scattered light, in the studio and is often required to supplement a large number of lights, as well as moderate adjustment of exposure to achieve the degree of high-key photography.|
|Scenarios||Low-key lighting is mainly used to express contradiction, fear, and contrast. Dramatic photography/film work, still life photography, and portraits are also often used.||High-key lighting is mainly used to express a sense of joy, lightness, and joy, mainly in advertising, personal portraits, family gatherings, and more relaxed works.|
|Emotional Expression||Low-key lighting forms a sense of gravity, solemnity, and rigidity, but in another environment, it will give people a sense of darkness, eerie, and fear.||High-key lighting mainly expresses brightness and lightness, while not highlighting the details, emphasizing the overall brightness, so the more prominent atmosphere is relaxed and pleasant.|
When you need to apply low-key lighting in photography, background, light, and camera are three main elements you should know.
To use natural light, you don't need all unobstructed natural light. Low-key photos need a small portion of light speed. Then how to get a small part of the natural light beam? You can make clever use of occlusion. When outdoors, the most common occluders are usually buildings or trees that can block the natural light while leaving a portion of the beam behind to highlight the contrast. As for indoors, the best use is windows, windows transmit most of the regular speed of light, but also can use curtains to control the speed of light, and the commission is really good.
The artificial light beam is better to control a beam, what beam is needed can be found. A more special beam is the flash that you use. Because what you need is not a whole light, but only a partial beam, so only a single flash is needed. Try not to consider using it head-on when shooting, try to use it in the upper part of the composition, or at other different angles such as the side, where you can make multiple attempts, so you can create high contrast for the low-key lighting.
In the camera settings, adjust to manually set the aperture and try to use a large aperture when low-key photos are needed so that the camera can sense light well in dark backgrounds. Of course, you can also adjust the camera to the following values, f/8 1/125 ISO 100, -2, is a more general value, but you can also adjust it to suit your situation.
When you need to make a perfect low-key image, a dark background is an indispensable factor. As for shooting portraits with low-key lighting, it should be best to the overall clothing to the dark color aligned. Of course, in the outdoor environment, try to pick the night or outdoor light is dim when you can also create a darker background.
