How to make a good sketch of life by using ambient light

Lead: Light is an important condition for photographic imaging, so mastering light can determine the quality and texture of the image. If you want to make a general distinction, you can use? Direction? 、? Light source color? With what? Lightweight? From three aspects, from the perspective of sketch photography, the directionality of light is often better than oblique light and backlight; The color of the light source has a considerable correlation with the light source; The texture of light usually depends on the medium through which the light passes before reaching the main body, or is influenced by the reflective surface. Below we use different photo examples to illustrate how to use light to make a good sketch of life.

How to make good use of ambient light to shoot oblique three-dimensional games in life sketches

Most shooting situations, including sketch photography, show the 3D world we live in in detail and subtly on the 2D plane. Because of this, the stronger the stereoscopic effect you display on the 2D photo screen, the more you can resonate with the audience, just like sharing photos with photographers? Now? . Oblique light is easy to form shadows in the picture, which makes the object have a turning point and a sense of depth, and naturally produces a three-dimensional sense. Even when the shadow itself is interesting, it often becomes the protagonist of sketch photography.

In the morning, the light passes through the bright yellow flowers of Compositae and leaves a shadow on the side road. It is interesting to compare them with each other. Shooting from a nearly vertical angle makes the shadow more obvious than the outline of the solid.

When shooting, the main light source comes from the natural light on the back and above, which adds a little exposure compensation. On the one hand, glass and translucent liquid are used to increase brightness, on the other hand, the background outside the window is removed.

Usually, the closer the height of the light source is to the height of the subject, the more the shadow is stretched, and the more obvious the dramatic effect is. Before and after adjusting the position of the light source, the direction in which the shadow appears changes. In sketch photography, when the sunlight is used as the light source, the sun cannot be moved, but the shooting theme and shooting position can be moved to achieve the effect; When using artificial light such as desk lamp and flash lamp, you can freely change the photographer, subject and light direction to find the most interesting shooting angle.

Backlight shows mysterious faces

Backlight is usually difficult to control the direction of exposure light, but the light will hook a beautiful edge light on the main body, so it is still popular with advanced players. When shooting in normal exposure mode, because the complete backlight will set off the outline of the subject, it is usually used on the subject with distinctive shooting form, so it is necessary to pay attention to clear outline and not overlap with other objects, otherwise this processing method is rarely used; With a little exposure compensation, although you can see the positive details, it looks dim. If the background is not too complicated, it will attract the audience to observe carefully and attract them. If the front exposure of the subject is correct, the background will usually appear dead white due to extreme overexposure, which can simplify the complex background, and the surrounding white background also gives the subject a quiet sense of sacredness, which is also the method adopted by many online players at present.

Therefore, the cherry blossoms under the sunshine are more dazzling and charming. Pay close attention to the backlight position, do not directly appear in the picture, and slightly reduce the exposure when shooting, so that the dark blue background can set off the beauty of white cherry blossoms.

Let the light pass through the ordinary plastic beverage cup, and you can shoot a gorgeous and dazzling feeling.

As for high dynamic range (HDR), it is usually not used for sketch images that are easy to shoot. If you want to reduce the contrast, you can use white reflective surfaces (white paper and white walls) to balance the brightness. When shooting with backlight, besides selecting exposure level, the processing of light source position is also a science. Usually, when the light source can be clearly seen on the screen, we will try to hide the light source behind the theme, which can reduce some contrast and the background light source will not become dead white. Sometimes carefully moving the lens position left and right can make the light source star shine from the side of the main body and make the picture have seeds? Decision moment? Interest.

Suggestions on the application of strong light

A ray of light scattered in the gap between branches and shadows, like a spotlight, makes the subject clearly and obviously emphasized.

The hard light of natural light usually appears when the weather is clear and the air is clean, and the sunlight is formed without the reflection or diffusion of clouds. When the light quality is hard, the contrast is large, and it is easy to produce strong shadows, which is more suitable for expressing images with strong personality. If you shoot with front light, sketch photography is usually not suitable because it directly presents the theme of the image, and there is usually less room for humor. On the contrary, it is more interesting to use shadows combined with front light to increase the imagination space. If you want to combine backlight processing, it is suitable for silhouette or transparent objects (drinks, glasses).

Soft diffuse light source

Which side is the physical box? The shadow edge presented by hard light is quite sharp, which makes the image easy to have personality.

The wall decoration in the shadow of the corridor always makes people feel relaxed. Increasing exposure will make the color appear brighter and more vivid.

Compared with hard light sources, in cloudy days, shadows, indoors and other areas, the light will be softer due to the influence of reflection and refraction, which is especially suitable for shooting soft-toned images. Especially the lovely and warm sketch pictures. Because the contrast of soft light is usually small and lacks directionality, it is very suitable for shooting from different angles of color and vision. Of course, when the light quality is not soft enough to have no directionality, it is also suitable for backlight treatment, which can preserve the color tone of the light source itself.

Color retention of light source? Now? atmosphere

Not only the physical object can become the protagonist of the image, but also the invisible light itself can form the main theme of the image. In many sketch photography, it seems that there is no theme, but it can convey the temperature and atmosphere for the viewer to understand intuitively? Now? This kind of image needs to carefully adjust the tone of the image, and use the balance of tone and transparent sense of space to create the visual experience of time and space at that time. Just like the dim light source in a restaurant, it will make the image look too yellow, but if it is completely adjusted back to the normal color, it will lose the feeling of live lighting.

The red color of Guam church is a heartfelt celebration of the wedding. Shoot with Panasonic GF2 filter effect.

There is a red thousand birds in the center of the palace lantern, which is warm and weak protection. With the red torii as the background, it is not too difficult to adjust the yellow light, just adjust the surrounding shadows and arrange the color temperature of the torii gap.

Because the brightness outside the window is extremely high, the brightness of small light bulbs with low power is not much different from the surrounding brightness. When shooting, as long as you don't overexpose, and then adjust the white balance around you to a cool tone, the light bulb will naturally show a bright yellow tone.

Shooting in such an environment, if you don't need a flash to correct the color light, it's best to leave some light sources that don't yellow in the picture, and increase the exposure as much as possible, and actively use RAW files to shoot. When using the computer for post-processing, carefully correct the color. First, adjust the white balance to the normal yellowish tone, and then gradually adjust and fine-tune the blue and green to make the color similar to that seen by the naked eye. Because of the light source other than yellow, it is easier to balance the image while retaining the yellow tone. If there is no yellow tone, you can try to bring in the bulb light source, so that the light source is almost white, and the halo next to it is yellow tone, which can also show the atmosphere of the field. The same principle can also be used in sunset and early morning sketch creation.
