Shutter operation method of SLR camera

What are the shutter speed and using environment skills of SLR photography? Shutter is the mechanism used by camera to control the effective exposure time of photosensitive film. It is an important part of the camera. Generally speaking, the larger the shutter time range, the better. Below, I sorted out the speed skills of opening the door with SLR photography. Welcome to read!

Shutter speed

Shutter is a device to prevent and control the length of light entering the camera lens. At present, the shutter speed of many cameras is automatically controlled by the camera, but it can still be set manually in some cameras such as SLR. Shutter speeds are 1, 1/2, 1/4, 1/8,1/5, 1/30,1.

Shutter speed and usage scene

male

Use a camera stand (such as a tripod). The opening time of the shutter is controlled by the time when the shutter button is pressed.

Usage scene: shoot fireworks and lightning, and record the stripe pattern formed by moving lights (such as driving lights) at night.

1 and 1/2 seconds

Use a camera stand (such as a tripod). Suitable for using small aperture to obtain large depth of field and sufficient exposure (such as spotlight or photographic lamp lighting) in dim light.

Usage scene: suitable for shooting inanimate objects and static objects.

1/4 seconds

Use the camera bracket. This is the slowest shutter speed suitable for taking portraits of adults. Under dim light conditions, it is appropriate to use a small aperture to obtain a large depth of field and sufficient exposure.

Usage scene: suitable for stable subjects.

1/8 seconds

Use the camera bracket. It is more suitable for shooting adults in a limited range than using the shutter speed of 1/4 seconds. Under dim light conditions, it is appropriate to use a small aperture to obtain a large depth of field and sufficient exposure.

Usage scene: suitable for stable subjects.

115 seconds

Use the camera bracket. When a standard lens or a wide-angle lens is installed on the camera, some people can take pictures with their hands if the camera can be held fairly smoothly during exposure. It is suitable to use a small aperture to obtain a larger depth of field and sufficient exposure in the case of dim light.

1/30 seconds

This shutter speed is the slowest shutter speed recommended when shooting with a hand-held camera and equipped with a standard lens or a wide-angle lens. In order to get high-definition photos, the camera must be held very smoothly. This shutter speed is suitable for most live light photography.

Usage scene: suitable for using small aperture to obtain large depth of field in cloudy weather or shadow.

1/60s

This shutter speed is suitable for taking pictures in cloudy weather, shadows and other outdoor sunlight when the lighting conditions are not ideal. This speed is useful for using a small aperture to increase the depth of field. This shutter speed is also used in places with bright spots. With this shutter speed, camera shake and shooting failure are less than with the shutter speed of 1/30 seconds.

Usage scene: suitable for flash synchronization of SLR cameras.

1125 seconds

This is the best shutter speed for taking pictures in outdoor sunlight. Under bright light conditions, using a medium aperture to a small aperture can produce a good depth of field. Using this shutter speed can minimize the weak vibration of the camera itself. You can master some medium-speed movements, such as walking people, children's games or free-moving babies. For hand-held cameras, this speed is safe to some extent when shooting with a medium focal length lens with a focal length less than105 mm. This shutter speed is recommended for some SLR cameras to shoot with flash.

Usage scene: moderate-speed sports, such as walking people, children's games or free-moving babies.

1/250 seconds

It is suitable for grasping sports bodies with average speed, such as middle-speed runners, swimmers, cyclists, horses running a certain distance, parades, running children, sailboats, baseball, football players playing at medium speed, etc. When you don't need a large depth of field, but mainly want to grasp the action, you can use this shutter speed in outdoor sunlight to minimize the vibration of the camera. Suitable for hand-held camera with 250mm focal length lens.

Usage scene: people who are moving at a moderate speed, etc.

1/500 seconds

It is suitable for capturing fast-moving objects, such as middle-distance athletes, running horses, divers, fast cyclists, running cars or basketball players. This shutter speed can be used to capture all moving objects except the fastest speed.

Usage scene: fast-moving characters, etc.

11000 seconds

This is the best speed to capture fast moving objects. Such as racing cars, motorcycles, airplanes, speedboats, outdoor and stadium competitions, tennis players, skiers and golfers. Because this shutter speed requires a larger aperture than other shutter speeds, its depth of field is the smallest. This is an excellent shutter speed when a hand-held camera is equipped with a long focal length lens with a focal length less than 400 mm.

Uses: Racing cars, motorcycles, airplanes and other fast-moving objects.
