When you pick up your camera and put on the telephoto lens, have you ever felt a wonderful change in the picture space?That distant world seems to be drawn closer, and the originally vast scene becomes compact and tense under the lens. This is the magic of telephoto lenses – the compression of the picture space.
1. The magic of telephoto lenses.
A telephoto lens generally refers to a lens with a focal length of more than 50mm. It is characterized by the ability to bring distant objects closer, so that the front and back elements of the picture seem to be "compressed" together. This effect is especially noticeable when shooting landscapes, portraits, and wildlife.
Second, the principle of space compression.
Spatial compression is actually a visual illusion. Because the telephoto lens has a narrow angle of view, it is able to magnify distant objects, reducing the sense of distance between the front and rear scenes. This effect is very noticeable when shooting scenes with a lot of depth, where the distance between the foreground and background is greatly reduced, giving the illusion that the front and back are closely connected.
3. Technical details and practical application.
Choose the right focal length: The longer the focal length, the more noticeable the spatial compression. However, it should be noted that an excessively long focal length may cause the sharpness of the image to deteriorate, so it is necessary to choose the appropriate focal length according to your needs in actual shooting.
Use the front and back scene composition: When shooting, you can deliberately select some scenes with rich front and back elements, and through the compression effect of the telephoto lens, these elements are tightly combined to form a layered picture.
Controlling the depth of field: The shallow depth of field of a telephoto lens means that you can control the focus position to create a picture effect that is clear in the front and clear in the back or blurred in the front and clear in the back when shooting, further enhancing the sense of spatial compression.
Fourth, the charm and challenges of telephoto lenses.
The spatial compression effect of a telephoto lens brings endless charm to the creation of photography. It helps photographers discover extraordinary beauty in ordinary scenes and create impactful and infectious works. However, the use of telephoto lenses also brings certain challenges, such as stability problems and focusing accuracy problems when shooting handheld. To overcome these problems, photographers need to constantly practice Xi and explore, and become familiar with the characteristics and usage techniques of telephoto lenses.
In short, the telephoto lens brings a new visual experience to photography creation with its unique space compression effect. Masters how to use it, photographers have more freedom to use this magical tool in their creations to create stunning photographic masterpieces.
