It depends on what camera you are using.
You can adjust the shutter speed of Canon EOS cameras so there isn't a set shutter speed.
Aperture Priority has the camera set the shutter speed for you allowing you to set the aperture and it will set what shutter speed it thinks is best for your current light situation.
Aperture priority lets you set the aperture you want and the camera sets the shutter speed for you. You use it when you want to control depth of field. Shutter priority lets you set the shutter speed you want and the camera sets the aperture for you. You use it when you want to control how motion is rendered in the photograph. Program mode sets both shutter speed and aperture for you. Use it when you are not concerned with aperture or shutter speed control.
The amount of time that the shutter remains open - allowing light to pass through it to form the image. Generally - a lower shutter speed would be combined with a smaller aperture and a higher shutter speed with a larger aperture to correctly expose the image.
Use shutter priority mode (S mode on dial) or manual mode (M on dial) and then select the speed you want by using the dials.
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 priority mode allows you to set the desired shutter speed while the camera adjusts the aperture, whereas aperture priority mode lets you choose the aperture setting while the camera adjusts the shutter speed.
The "S" on the display screen of your Instax camera stands for "Shutter Speed." It indicates that the camera is set to a specific shutter speed setting for capturing photos.
It depends on what camera your using, some have it so that the shutter will stay open for seconds long. Some have a,"bulb" mode where the shutter stays open for the whole time you have the shutter-release button pressed.
You have it set wrong. You can change the shutter speed in the menu
To change the shutter speed on a Nikon D90, turn the mode dial to "S" for Shutter Priority mode. Then, use the command dial to adjust the shutter speed to your desired setting.
Shutter speed and exposure in photography are closely related. Shutter speed refers to the amount of time the camera's shutter is open to allow light to hit the camera sensor. A faster shutter speed lets in less light, resulting in a darker image, while a slower shutter speed lets in more light, resulting in a brighter image. Therefore, adjusting the shutter speed directly affects the exposure of a photograph.
