The question is incomplete.
It would depend on the lighting conditions of where and what you are trying to capture an image of, as well as depend on the desired outcome of the image.
In a very dark room, you may need "more light" than you would in a brightly lit room.
The shutter speed will determine how much light can enter and be captured, which is determined by what the photographer wants to show in the final image.
Shutter speed is how fast your shutter opens and closes to take a picture on your camera. Shutter speed also has a lot to do with exposure. The higher the shutter speed (1/2000 example) the less light.
"Shutter Angle" refers to rotary shutters used in motion picture cameras, a lower shutter angle (in degrees) means less light is allowed to expose the film and less motion blur is captured, higher angle and more light is let and more motion blur appear on flim. 180 degrees or 1/48th of a second (at 24 fps) is considered normal. The shutter angle is controlled by the shape of the rotary shutter, some cameras allow you to change the shape of the shutter or swap out for different shape shutters. Some newer or high-end cameras allow you to change the shape of the shutter while still in-camera. Your question was filed under photography, so possibly you mean "shutter speed" if your camera allows for manual control of the shutter speed it will be in 1/Nth of a second increments. A shutter speed of 1/125th of a second was taught to me as a good shutter speed to start at for medium focal lengths for a beginning shooter - to avoid blurry pictures. Also, if you're trying to freeze water in motion, birds in flight or people in motion, a high shutter speed will work well. Above 1/500th or 1/1000th of second if your camera is capable will create the desired effect. To answer effectively we probably need to know the model of camera you are using, and the purpose, happy shooting!
1/125 of a second.
The first number is referring to the aperture (f/8 or F8) and the second number to the shutter speed (1/2000 sec.).
It is associated with the length of time a photosensitive surface is exposed to light.
It is measured in a fraction of a second. For example 1/500th of a second
To freeze motion in photography, a fast shutter speed should be used, typically around 1/500th of a second or faster.
For capturing fast-moving subjects on a Nikon D90, it is recommended to use a shutter speed of at least 1/500th of a second or faster.
The recommended shutter speed setting for capturing fast-moving subjects to avoid motion blur is typically 1/500th of a second or faster.
For capturing fast-moving subjects with a Nikon D3100, it is recommended to use a shutter speed of at least 1/500th of a second or faster to freeze the motion and avoid blur.
For capturing fast-moving subjects with a Nikon D7000, it is recommended to use a shutter speed of at least 1/500th of a second or faster to freeze the motion and avoid blur.
For capturing fast-moving subjects with a Nikon D90, it is recommended to use a shutter speed of at least 1/500th of a second or faster to freeze the motion and avoid blur.
For capturing fast-moving subjects on a Canon Rebel T7, it is recommended to use a shutter speed of at least 1/500th of a second or faster to freeze the motion and avoid blur.
Shutter speed is how fast your shutter opens and closes to take a picture on your camera. Shutter speed also has a lot to do with exposure. The higher the shutter speed (1/2000 example) the less light.
To capture fast-moving subjects with a DSLR camera, adjust the shutter speed to a faster setting. This will help freeze the motion and prevent blurriness. Start with a shutter speed of at least 1/500th of a second and increase it as needed. Experiment with different speeds to find the best setting for the specific subject and lighting conditions.
Shutter speed controls the amount of time the camera's shutter is open, determining how much light reaches the sensor. A faster shutter speed lets in less light, while a slower speed lets in more light.
Slow shutter speed - keeps the shutter curtain open for longer periods of time, e.g. when you shoot at night or in fading low light. Fast shutter speeds are used to capture action or when scene you are trying to shoot is well lit. In this case the shutter opens and closes in a fraction of a second!
