Hello, everyone. I'm Yingye.

This tutorial will talk to you about the characteristics of the focal section in photography and how to select the focal length and field of view in the shooting process.

First of all, it is necessary to make it clear that the focal length does not determine the field of view, which does not mean that the field of view must be a local close-up when shooting with medium-long focal length, but it may also be local when shooting with a wide-angle lens. For example, if we want to take a panoramic view of an object, we can get it at close range with a wide angle and at a distance from the telephoto station, but the visual effect is different at this time.

The range of vision is more directly related to how far we are from the subject. The focal length of the lens will more affect the perspective effect of the picture, the sense of virtual compression, visual impact and so on, which can be called visual effects.

When shooting, we should consider the visual field range and visual effect, select the focal length according to the visual effect, and adjust the shooting distance according to the desired visual field range.

50mm classic focal length 50mm focal length is very classic, 50mm fixed focus lens is regarded by many people as a must-buy lens for beginners, this is because the angle of view of 50mm is most in line with the visual field of the human eye, and the effect is very close to that of our naked eye, so it is most easy for beginners to get used to it and will not cause inadaptability in composition.

This is the most common 50mm photo shoot, mainly with half-body close-ups and virtual background, but also because 50mm has no wide-angle tension and no telephoto compression, so the visual effects will appear dull and lack of characteristics. At this time, it is necessary to design the scene and composition to make the picture more interesting.

For example, behind the character design light source, create outline light, create light and shade contrast.

It can also increase the foreground mask and explain the sense of space and hierarchy. When shooting at a long distance, 50mm can also take full-body portraits and a clear environment, so that the field of view and visual effects are different.

However, because the 50mm focal section lacks wide-angle tension and long focal compression, it is not recommended to use it frequently. We should try other focal segments to achieve a rich expression effect.

When shooting scenery, 50mm is suitable for shooting local scenery, which requires attractive light and shadow or line structure of the scene itself, in order to make up for the insipid effect of the focal part of the lens.

Whether it is shooting scenery or portraits, it is necessary to use the composition, light and shadow, color and other information in the scene to make up for the lack of imaging characteristics of 50mm.

24 to 35mm wide-angle standard wide-angle standard is characterized by a large field of vision, but the distortion is not exaggerated, will not cause obvious deformation to the characters, so it is commonly used in indoor portraits.

Compared with 50mm and telephoto, this kind of lens has no strong virtual background and can capture a clearer environment, so when we want to express the needs of the picture through environment assistance, we can choose 24 or 35mm.

35mm is easier for beginners to master because the wide angle is slightly smaller and it is less difficult to arrange the scene. But I prefer to use 24mm because it brings stronger visual impact.

Shooting portraits with standard wide-angle is not for the purpose of shooting more environmental content, but for the visual impact of wide-angle close-up shooting, so I choose a closer shooting distance. Like the above work, I use 24mm to fix the focus, but instead of shooting the whole house, I only shoot people and pianos. The visual effect of wide-angle close-up shot is absolutely different from that of 50mm.

The focus from 24 to 35mm is also suitable for shooting scenery, so the classic scenery lens is 16-35 and 14-24. Sometimes there are sundries in the surrounding environment, so it is necessary to narrow the field of vision properly.

14 to 20mm ultra-wide-angle ultra-wide-angle can not only accommodate a wider range, but also extremely strong tension and perspective effect, if there is a foreground in the picture, you can get more exaggerated visual effects.

The foreground of the above picture is originally a very small sink on the beach. When shooting at a low position with a wide angle, there will be an obvious focus perspective, which will highlight the foreground and enhance the spatial depth.

Ultra-wide-angle vertical composition can accommodate many vertical levels, from their own feet to the distance of the main body can be accommodated, so in landscape photography often see this way of composition.

In the urban scenery, the ultra-wide-angle top shot is usually used to climb the view of buildings, reflecting the grandeur of high-rise buildings.

Ground position, ultra-wide angle is used to express the height or sense of space of the building.

In the theme of environmental portraits, ultra-wide-angle shooting can highlight the atmosphere of the environment, and often use ultra-wide-angle close-up shots to express visual effects, which can have a stronger visual impact.

At this time, the character acts as a core element in the picture, and the costume and action of the character can convey the style and emotion of the work, and express the story of the picture through the environment.

85 to 200mm long focal length does not necessarily mean shooting a close-up, its most characteristic lies in the sense of compression and virtual, which can not be replaced by other focal segments.

Shooting portraits in medium and long telephoto is not necessarily to capture local close-ups, we are for the telephoto compression of the picture, so I am used to shooting a full-body perspective with environment from a long distance, which has both environment and virtual and real levels.

The 85mm focus in the night portrait is more appropriate than 70-200, because the 85mm has a very large aperture of 1.8 or 1.4, and the image quality is much better than the 2.8aperture in the night scene.

Capturing local lines with medium-long focus in the desert is more lasting than shooting a large scene with a wide angle. Shooting in side light at sunrise or sunset is more three-dimensional.

In the urban scenery, sometimes want to express the hierarchical contrast between buildings, it is usually not recommended to use ultra-wide angle, wide-angle upside-down shooting will bring greater deformation and lack of compression. So when we shoot with telephoto, the relative angle will be much smaller, and the sense of compression will make the layer more attractive.

The above is the explanation and use suggestions on the characteristics of each focus section, hoping to give you some clearer shooting ideas.
