What are aperture and shutter, and how do they fit together?

With the rapid development of the media industry, more and more videos and pictures can be shared online, especially for some girls who like to take selfies. To make photos look better, people often use some retouching software. For some professional photographers, a good picture needs not only additional auxiliary software, but also good photography skills. In fact, aperture and shutter are the most sensitive conditions in a camera. What are aperture and shutter?

What are the aperture and shutter?

The speed of the shutter is in seconds. Common shutter speeds are:11/21/41/81151/301/60/kloc. The shutter speed exposure of two adjacent stages is twice different, and we often say that the difference is one stage. For example, the exposure of1/60s is twice that of1125s, that is,1125s is one step slower or one step lower, and the exposure of1/60s is 65430s. The English name of Aperture is aperture, which is used to control the amount of light entering the photosensitive surface of the fuselage through the lens. It is an extremely important index parameter of the lens, and the aperture is usually in the lens. Its size determines how much light enters the photosensitive element through the lens. Usually we use the value of f to indicate the size of the aperture. The shutter is the part that controls the exposure time of the camera, and the shutter speed is in seconds. Common shutter speeds are:11/21/41/81151/301/60/kloc.

How to match the aperture and shutter?

When shooting a moving object, we must first determine the shutter speed: when shooting a moving person or object, the shutter speed must be high enough to solidify it, otherwise there will be no clear image. Shutter speed depends on the speed of moving objects; The included angle between the moving direction of the moving object and the shooting direction; The distance between the moving object and the camera. The faster the moving body moves, the higher the shutter speed; The greater the angle between the moving direction of the moving object and the shooting direction, the higher the shutter speed; The closer the moving object is to the camera, the higher the shutter speed. In short, the highest shutter speed is needed to shoot an object moving at a high speed of 90 degrees at close range.

To shoot still life, we must first determine the aperture: the aperture size is different, which involves the depth of field. For example, when taking a commemorative photo, people stand 5 meters away from the camera, and the scenery between 3 and 20 meters is required to be clear. In case of Jing Shenbiao detection, the aperture of F 1 1 should be selected. For another example, when shooting a bust or close-up or close-up, in order to show the facial level or discard the messy objects on the background, you should choose a larger aperture. Large aperture is helpful to improve the shutter speed and express the theme, but it is also important to control the depth of field appropriately so that the image is not too loose.

Therefore, a good photo depends largely on the skill of the photographer. In addition to the aperture and shutter mentioned above, there are also some parameters closely related to the quality of our photos. For us ordinary people, a good photo can record our life and share every moment with friends. But for photographers, photos are their own works, and the quality of their works is related to their own Excellence, and for them, every parameter is crucial.
