Portrait skills with telephoto lens and stability of telephoto lens
Portrait photography is the most extensive photography subject. Whether you are a novice photographer or an experienced photographer, there is no shortage of people who use a telephoto lens. Today, on how to make full use of the advantages of telephoto lenses to express portraits, I will share with you some tips on shooting portraits with telephoto lenses.
1. The benefits of taking portraits with a long focal length
Today I will introduce the advantages of taking portraits with a medium telephoto. The choice of focal length directly affects the proportion of the subject in the frame, thereby determining the visual effect of the photo. The reason is that it is easy to use. The zoom lens can zoom in or zoom out in place. This is of course a simple method of composition, but it is by no means the best way to shoot portraits.
The advantage of using a medium-telephoto lens is that the photos taken have less distortion, normal perspective, and easy operation. Because of its small shooting angle, shallow depth of field, and a significant compression effect on the scene, it can blur the messy scene, make the characters more prominent, and the picture more stable.
Second, the experience of using telephoto
The telephoto lens can bring people and scenery in the distance closer, strongly Compressing the space makes the picture quite concise, compact and full, blurring the foreground and background, accentuating the subject, and gaining the beauty of overlapping sceneries on the basis of the apparently weakened perspective effect.
1, the benefits of the 85 lens:
It is well known that the 85mm lens is a portrait lens design head, a fixed focus head. Large aperture, good light transmission, oily and soft picture quality. It is very suitable for shooting half-length portraits and use in specific environments. When shooting close-up pictures, the 85mm lens has the characteristics of no distortion compared with the standard lens or wide-angle lens, which is very suitable for close-up emotional description. Compared with a longer focal length lens, the 85 is closer to the perspective of the natural human eye, and does not compress the environment into a background plate.
2, 85mm compared with 50mm and 35mm:
85 has both a large aperture to highlight the subject and portraits Features of non-deformation. Compared with the 50 and 35, the background blur is more obvious. As a portrait head, it has a certain optimization for the skin color of the person, especially when the weather is bad. But the performance of the environment is not as rich as 50 or 30.
3. Telephoto framing techniques
The telephoto framing still follows several composition rules, such as three-part composition, Diagonal composition, Tic Tac Toe composition, etc. In addition, the unique compression of telephoto makes it easier to capture the use of the foreground. For shooting in the city, telephoto has its advantages for capturing depth. For example, tunnels, passages, bridge piers, street lights, etc. are particularly suitable for telephoto. In the wild, telephoto is also the best choice if you want to bring the distant scenery closer to behind the model.
The stability of the telephoto lens:
The advancement of optical lens technology has made the size of the telephoto lens smaller than before A lot of them, but they are much larger and heavier than other types of lenses, and they are not easy to carry. Especially like a large-aperture telephoto lens with a maximum aperture of f2.8 or f4, the size and weight are considerable. The increase in body size is not caused by the magnification of the lens, but is the result of achieving a larger aperture. The weight and length of the lens will affect the photographer's ability to keep the camera stable during shooting. At low shutter speeds, camera shake is more likely to occur.
Using a telephoto lens, image stabilization technology can reduce the impact of vibration, but it cannot replace a stable support. Regarding the support, a tripod is the best choice. If not, a monopole can also be temporarily replaced. Photographers shooting nature and sports especially need these supports to help.
Long focal length telephoto lenses are usually designed with a tripod mount, and there is no need to connect and fix the camera and a tripod. This can make the weight distribution of the camera and the lens more balanced, and Reduce the pressure on the lens mount. If you have no other choice but to shoot handheld, it is best to use high-speed shutter first. Here is a general rule for your reference, shutter speed and lens focal length are the reciprocal of each other. For example, if you want to get a clear image with a 400mm focal length lens, you must at least adjust the shutter speed to 1/400 second or faster.
