What are the lighting skills of photography?

Photographic light mainly includes four characteristics? The intensity, nature, directionality and color of light. Let's take a look at the division of photographic light with me!

Guang Shun 1

Also called positive light and peaceful light. Light shines from the front of the subject, which is characterized by high brightness, flat image and good color reproduction, but the light is relatively flat, so it is difficult to show three-dimensional sense.

2. Indirect explanation

Light comes from the side of the subject and is usually divided into front light and backlight. It is characterized by obvious three-dimensional sense of the subject, richer tone levels and line outlines, and can better depict the appearance characteristics and expressions of characters.

3. Backlighting

Also known as? Backlight? . The light comes from the back or oblique back of the subject, which is characterized by drawing a beautiful outline for the subject, distinguishing the characters from the background, and showing a strong sense of space.

4. Direct light

Also known as? Strong light? . Outdoor generally refers to the light emitted by the sun on a sunny day, which is characterized by strong directionality, and can form a strong contrast between light and shade and a three-dimensional sense when illuminated on the subject, which has a relatively tough effect.

5. Scattered light

Also known as? Soft light? . Outdoor generally refers to sunlight passing through clouds or being reflected by the ground, walls, etc. It is characterized by no clear directionality, no obvious relationship between light and shade when shining on the subject, rich intermediate transition layer and softer image. This kind of light is the ideal light for shooting portraits, and the skin layers of the characters are very rich.

Photometric measurement

Multi-area photometry

Multi-area photometry is also called evaluation photometry, which divides the picture into several areas. Calculate independently and then sort it out. In order to obtain a complete exposure value, multi-area photometry often gives priority to the main target to be focused, because in most cases, the main target of focusing is the part that needs to be exposed correctly. Multi-area photometry can easily obtain accurate exposure results even for people who know nothing about photography. Therefore, multi-area metering is an advanced and popular metering method at present, and it is also the default metering method for high-end automatic cameras at present.

Central key average photometry

Central focus average metering is a metering mode widely used by most cameras, and it is also a widely used one. Central focus photometry means that the exposure reading is most affected by the central area and least affected by the four corners of the picture. Generally, central focus photometry is sensitive to the central 2/3 part of the picture (the specific scope varies according to different camera brands), and some cameras pay attention to the bottom of the picture to reduce the influence of the sky on the scenery. Under normal shooting conditions, central focus photometry is a very practical photometry chess, but if the main body of the picture is not in the center or shot in reverse light, it may cause.

Spot photometry

Spot metering, also called focus metering, is the framing range of 1%? 5% area measurement. Spot metering mode is rarely used and is not easy to master. But in some cases, spot metering can play an important role. Knowing when spot metering should be used and using spot metering correctly can make the exposure of the subject accurate on the one hand and use it on the other. Sensitivity tolerance? To create wonderful pictures that can't be seen in reality.

Application of spot metering mode: in the case of uneven light distribution and large contrast, such as backlight, if spot metering is not used in this case, the exposure of the subject to be represented may be inaccurate. When it is too bright, the subject becomes a silhouette, and the picture is white without layers, or it is too dark to see the details clearly.
