45 degree light in photography

1, Guang Shun: Also called "frontal light", it refers to the light with the same projection direction and shooting direction. Under such light irradiation, the subject receives light evenly, the scenery has no big shadow, and the color is saturated, which can show rich color effects. However, because there is no obvious contrast between light and shade, the performance of layering and three-dimensional sense is poor. But when shooting the theme of women and children in the light, it can show its delicate skin well.

2. Photometry: Photometry is the most commonly used light in photography, and the included angle between the projection direction of side light and the shooting direction is more than 0 degrees and less than 90 degrees. When shooting by photometry, the contrast between light and shade, stereoscopic impression, color reproduction and tone level of the subject have a good performance. Among them, 45-degree angle photometry is the most suitable for people's visual habits, so it is the most commonly used light level. Photometry is very suitable for expressing the three-dimensional sense of mountains, buildings and portraits.

3. Front-side light: Front-side light refers to light whose projection direction makes an angle of about 45 degrees with the optical axis direction of the lens. Under the front light irradiation, the overall tone of the subject is brighter, but compared with the front light irradiation, its brightness is smaller, and the subject is partially illuminated with a small amount of projection.

It is conducive to the presentation of its three-dimensional sense, but also conducive to the formation of a good relationship between light and shade of the main body, which can better express its surface structure and texture. When using the front light to shoot portraits or landscapes, it can make the picture look very stereoscopic.

4. Backlight: Also called Backlight, the direction of light irradiation is just opposite to the shooting direction. Because it can outline the brightness outline of the subject, it is also called side light. Backlight is often used to show the silhouette effect of portraits (usually need to fill the light when shooting), mountains and buildings. When this light is used to shoot insects with hair or translucent wings, beautiful silhouette light can be formed, thus setting off the subject well.

5. Side backlight: refers to the light whose projection direction makes an angle of about 135 degrees with the optical axis of the lens. Because there is no need to look directly at the light source when shooting with side backlight.

So there is no need to consider glare when shooting. Under the illumination of side backlight, the image often forms a dark tone effect, which is mostly used to emphasize the shape of the external contour of the object, and is also an ideal light to express the three-dimensional effect of the object. Side backlight is often used to show the outline of portraits (which need to be filled with light when shooting), mountains, buildings and other themes.
