Control technology of external lighting and color tone

Lead: I think the most important thing in location shooting is how to view and control the light. The framing determines the style and aesthetics of the picture. The control of light determines the hue and shadow. Let's take a look at some skills!

1, cloudy to cloudy light

This kind of scattered light is very soft and is an ideal light in portrait photography. In this light, the character's skin is delicate, clean and textured, and the character's eyes will be very comfortable in this light. However, the contrast between scenes in this light is small, and the sky is too monotonous and lacks color. However, you can choose the color mirror or the white balance mode of the camera to change the tone of the sky. For example, when shooting in color mode, you can choose an orange gradient lens or a brown gradient lens to create a dusk effect, or the camera can change the color of the sky in cold and warm mode; When shooting in black and white mode, you can choose a gray gradient lens to darken the sky; You can also choose a brighter background and a soft mirror to create a dreamy effect of light color.

? Ordinary effect of cloudy shooting

If there is no ordinary background of the sky, you can directly measure the brightness of the face to determine the exposure of the camera. At this point, people's faces can be filled with reflectors. Because the contrast between human face and background is small, flash can be used to simulate the effect of sunny day backlight or side backlight to illuminate human contour. When the flash is used as profile light, its illuminance index is 0.5 larger than the aperture value used by the camera. About 1.

? Shooting in a cloudy background dominated by the sky.

At this time, you can add orange gradient mirror, medium yellow mirror, brown mirror or different white balance modes in the sky to change the monotonous effect of the sky. When measuring light, add the required color lens in front of the lens and measure the sky to determine the exposure combination of the camera. At this point, people's face should be filled with flash light, and the index of light filling should be equal to or slightly larger than the aperture value used by the camera.

In addition, the flash can also be used as backlight or side backlight to shoot silhouette effect or bright line effect.

2. It's sunny and sunny.

This kind of light has a large light receiving area, a clean face and few shadows. However, the level of light and shade between scenes is not obvious, the contrast is small, the three-dimensional sense is poor, and the light shines directly on the face of the person, which makes the eyes uncomfortable. At this time, the modeling arrangement of the characters can be based on the romantic feeling of closing their eyes. This kind of light is very suitable for shooting blue sky and green water.

? Blue sky effect shooting

When metering, you can determine the exposure combination of the camera according to the brightness of the main color blue in the sky. A person's face should be filled with flash light, the direction of which should be consistent with the direction of sunlight, and the index of which should be the same as or slightly smaller than the aperture value used by the camera. On the other side of the picture, you can also use a reflector to fill the light.

If you want to emphasize the effect of blue sky, you can add a gray gradient lens and polarizer in front of the camera; It can also reduce the exposure of the sky, darken the sky and deepen the blue sky effect; You can also use the tungsten lamp white balance mode, and add a Rayden 85 lens in front of the flash to supplement the light of the character and restore the skin color of the character's face.

Note: When adding a polarizer to darken the sky, the exposure of the camera should be compensated by 1. At this time, the fill light index of the flash is increased by 1 compared with the aperture used by the camera.

? Shooting of green water surface effect

Choose the green water surface under smooth light as the background. When measuring light, you can directly determine the exposure combination of the camera according to the brightness of the face. The person's face is filled with reflector according to the situation. At this time, you can also use cool colors to express the picture, giving people a sense of Jing Ya.

3. Sunward side light, side backlight, backlight

This kind of light can make the scenery have a bright outline, which can fully show the texture of leaves, translucent objects and gauze clothes. At the same time, the contrast between the scenes is large, and the three-dimensional sense and layering are strong, which also makes many shadows appear on the face of the characters. But this kind of light is the most commonly used light in photography, and it is an ideal light for shooting dusk effect, silhouette effect, dream effect, water light effect and night scene effect during the day.

? Shooting of common effects such as side light, side backlight and backlight.

Choose the background with light transmission under side light, side backlight and backlight, and the light and shade levels are rich. When measuring light, the camera exposure combination is determined according to the brightness of the face. At this time, people's faces can be filled with reflectors. If the background is darkened by reducing the exposure, a flash should be used to fill the light, and the fill light index of the flash should be equal to the aperture value used by the camera.

? Twilight effect shooting

Select the sky or water surface with backlight or side backlight as the main background. When measuring light, add the required color mirror and measure the brightness of the main color of the background to determine the exposure combination of the camera. Generally, an orange gradient mirror, a brown gradient mirror and a medium yellow mirror can be added in front of the camera lens to exaggerate the color of the sky. At this time, people's face should be filled with flash light, and the index of light filling can be equal to or slightly larger than the aperture value used by the camera. ? Silhouette effect shooting

Choose the bright color of backlight or side backlight as the background, or choose the background with backlight effect, such as bright window as the background, sky as the background or bright water as the background. The exposure of the camera can exceed 1 according to the brightness of the background. Secondary exposure. The figure's modeling should be based on the outline, and the outline of the face and body must be clear and set off with bright colors. At this time, the face of the character can form a full silhouette effect without filling light. At the same time, you can also use brown mirror, orange mirror, gradient mirror or camera white balance mode in front of the camera to create the effect.

? Dream effect shooting

Choose a background with side backlight or strong backlight transmission, that is, choose a background with strong contrast between light and dark. When measuring light, measure light according to the brightness of people's faces. A soft mirror or a hollow soft mirror should be added in front of the camera. At this time, the human face can be filled with light through the reflector.

Note: When shooting with a longer focal length or a larger aperture, the illusion effect is more obvious.

? Shooting of water surface effect of backlight

Select the water surface illuminated by backlight or side backlight as the background.

A. When determining the exposure combination of the camera with the brightness photometry of the deep color of the water surface as a reference, you can use warm color film or the white balance mode of the camera to shoot the effect of the sunset water surface. A person's face should be filled with flash light, and the index of filling light should be equal to the aperture value used by the camera. At this time, if there is a light spot on the water surface, you can add a starlight mirror in front of the lens to emphasize the sparkling effect.

B, if the silhouette effect is shot by the water surface backlight, then turn on the light according to the brightness of the background 1? Secondary exposure of shooting.

C. If you shoot a high-profile effect with water, you can expose it according to the person's face. At the same time, you can also use hollow soft mirrors to emphasize the elegant and dreamy effect.

4. Light or shadow in the shade on a sunny day

This kind of light has the characteristics of cloudy light, but the brightness of light under the shade is very different from that outside the shade. If the exposure control is not good, the background will be overexposed and lose some colors or the brightness of the dark part will be greatly reduced and some layers will be lost. Therefore, exposure control in the shadow is a key link.

? Shoot people in the shadows.

Firstly, the brightness value of the main color in the background in the sunlight is measured, then the brightness value of the main color in the shadow in the background is measured, and then the exposure combination of the camera is determined according to the average value of the two brightness photometry. In addition, 18% gray board can be used for photometry in the sun, and the exposure value obtained is also the average exposure value. At this point, people's faces should be filled with reflector or flash, and the index of flash filling should be equal to the aperture value used by the camera.
