Shutter priority operation method

Aperture priority is the opposite. Shutter priority is to manually define the shutter value of exposure, and the camera will determine the aperture size according to this shutter value. Set the camera dial to S, or set the exposure mode to S in the menu, which is the shutter priority function.

In the shutter priority mode, the camera will automatically adjust the aperture f value to the normal exposure level according to the shutter speed value set by the photographer. Shutter priority mode is usually used to "capture" moving objects and give priority to capturing dynamic images.

For Sony F/H series cameras, the shutter priority mode setting steps are as follows: first, turn the letter "S" on the mode knob of the digital camera to the position opposite to the power indicator, and the camera will be in the shutter priority shooting state; Then you can increase or decrease the shutter speed by turning the "button" on the right side of the shutter. The change of shutter speed setting is visually displayed on the LCD screen.

For Canon series cameras, turn the letter "Tv" on the "mode knob" to the position opposite to the power indicator, and the camera is in the shutter priority shooting state. Press the select key "set" or "ok" on the back of the camera to change a specific shutter speed setting.

Due to the different brands and models of digital cameras, the specific operation of selecting shutter priority mode and setting shutter speed is slightly different, and so is the screen display. Please pay attention to reading the relevant contents in your camera manual. Increasing or decreasing the shutter speed can not only adjust the exposure, but also have different effects when shooting dynamic objects with different shutter speeds. The advantage of using high-speed shutter is that it can overcome the interference of camera vibration and object motion, make it fast, and make the fast-moving subject instantly fixed; The disadvantage is that when adjusting the shutter speed, factors such as aperture size and exposure compensation should be considered, because high-speed shutter will reduce the amount of light entering and the film will be dark, especially for indoor shooting. Setting a relatively slow shutter speed and following the shooting (panning) method can make the picture have a strong dynamic effect; However, if the shutter speed is too slow, the slight shaking when holding the camera will lead to blurred images.

Generally speaking, the shutter speed to prevent hand shake is "1/ lens focal length (seconds)", which is an empirical value, also called safety shutter. For example, the camera of 135 uses a lens with a focal length of 85mm, and the shutter speed that can effectively and clearly shoot the subject should not be lower than 1/85 seconds. By analogy, when the focal length of the lens is 200mm, the shutter speed should be set above 1/200 seconds. It should be noted that if a common digital camera (DC) or a non-Quan Huafu digital SLR camera is used, the focal length should be converted to that of 135 camera. If a 50mm lens is used on the Canon EOS 400D, the safety shutter is1(50×1.6) =1/80 seconds. Moreover, the safety shutter will generally improve the success rate of shooting, but the photos taken at a shutter speed lower than the safety shutter may not necessarily fail.

The shutter speed of the camera was originally only one of the means to control the exposure, but if used properly, it can also be a "secret weapon" to achieve special photographic effects. Therefore, the setting and application of "shutter priority" is also one of the most basic skills in photography. If we want to shoot moving scenes, should the shutter speed be faster or slower? This is not absolute, the key is to see what creativity to show. If the subject being photographed is undergoing a series of rapid movements, we can choose to slow down the shutter speed to shoot if we want to show its movement. Because the shutter speed is too fast, it can only take a moment of static action, just like the freeze frame in the film and television, which can't reflect that kind of dynamic feeling.

However, freeze-frame is also a kind of beauty. If we freeze a moving object into a beautiful picture, it is also a good photo.

The setting of high-speed shutter is suitable for capturing dynamic objects. When capturing fast-moving people, it is suggested that the hand-held camera should track the subject forward, so that the subject is always in the best position in the picture. At the same time, keep the "half-pressed shutter" state, so as to press the shutter in time at the best time.
