What are the skills of visual photography?

Visual photography is presented in the form of visual art with a camera. Create a beautiful shock visually. Including macro photography, underwater photography, infrared photography, pinhole photography and so on. Visual photography attaches great importance to the freshness of the senses. So what are the techniques of visual photography? Come and have a look with me!

Visual photography skills

The website of visual photography and technical discussion area collect photographic materials such as lighting, equipment, beauty and digital post-production, so that readers can selectively read and learn different careers in photography, and photographers of different levels can find their own learning materials here.

Portrait photography photometry

Usually portrait shooting and photometry are done on the face, or more strictly speaking, on the eyes. Use central focus or spot metering to move the metering point in the framing window to the face position, move to the correct composition after metering, and press the shutter. Because we usually take negative pictures of portraits, it is best to overexpose them by about 0.3 to 1, and the effect will be better when developing them. "The negative is on the top, the positive is on the bottom" is a mantra that many photographers often talk about.

Portrait photography aperture

Portrait photographer Huang uses a large aperture to get a shallow depth of field. It will be more prominent when the proportion of the main body is not very large. Another advantage of using a large aperture is that the shutter speed will not be slower than the safety limit when the weather is dark.

Portrait photography exposure

Correct exposure is the basic element of taking photos, and exposure is determined by aperture and shutter, so how to choose the combination of aperture and shutter is the most basic skill of shooting. Now many digital cameras have S (shutter priority) and A (aperture priority) shooting modes:

Aperture priority is to manually define the size of the aperture, and then use the camera's metering to obtain the corresponding shutter value. Because the aperture directly affects the depth of field, this mode is most widely used in ordinary shooting. When shooting portraits, we usually use large aperture and long focal length to blur the background and get a shallow depth of field, which can highlight the subject. At the same time, a larger aperture can also obtain a faster shutter value, thus improving the stability of hand-held shooting. When taking photos such as scenery, we often use a smaller aperture value, so that the range of depth of field is wider, which can make the distant and nearby scenery clear, which is also applicable when shooting night scenes.

Contrary to aperture priority, shutter priority is to obtain aperture value through camera metering when the shutter is defined manually. Shutter priority is mostly used to shoot moving objects, especially sports shooting. Many friends find that when shooting moving objects, the subject is blurred, mostly because the shutter speed is not fast enough. In this case, you can use the shutter priority mode, roughly determine a shutter value, and then shoot. And the motion of the object is generally regular, then the shutter value can also be roughly estimated. For example, the shutter speed for photographing pedestrians is only1125 seconds, while it takes11000 seconds for photographing falling water droplets.

In the case of aperture priority, we can easily control the depth of field by changing the aperture size, while in the case of shutter priority, using different apertures can achieve good shooting results for moving objects. Both should be used flexibly to meet our shooting needs in different situations.
