Have you ever wondered if video cameras have a shutter? The answer is yes!
However, it works a bit differently than the shutter on a traditional still camera. Let’s dive into the details.
What is a Shutter?
Before we get into how a shutter works on a video camera, let’s first define what a shutter is. In photography, the shutter is a mechanism that controls the amount of time that light is allowed to enter the camera’s sensor or film. It opens and closes to expose the sensor or film to light for a certain duration of time.
How Does Shutter Work in Video Cameras?
In video cameras, there is also a mechanism that controls exposure called an electronic shutter. The electronic shutter works by turning on and off the camera’s sensor for specific periods of time to allow light to enter and expose the sensor.
Unlike with still photography, where you can control how long the shutter stays open, in video mode, there are limitations. Video cameras have set frame rates at which they record video, typically 24 frames per second (fps) or 30 fps. Each frame has an exposure time that corresponds with these frame rates.
For example, at 24fps, each frame is exposed for 1/24th of a second. At 30fps, each frame is exposed for 1/30th of a second. This means that when you press record on your video camera, it will continue taking photos and exposing the sensor at these set intervals until you stop recording.
The Role of Shutter Speed in Video Cameras
While you cannot manually adjust the exposure time like you can with still photography, there are ways to adjust how much light enters your camera’s sensor using other settings such as aperture and ISO.
Shutter speed does play an essential role in video cameras even though it operates differently than in still photography. As mentioned earlier, the electronic shutter turns on and off the sensor for specific periods of time to allow light to enter and expose the sensor. The duration of this time can affect how motion appears in your video.
A faster shutter speed will give you a sharper image with less motion blur, while a slower shutter speed will give you more motion blur and a more cinematic feel. However, it’s important to note that changing the shutter speed can also affect how much light enters the camera’s sensor, so adjustments to aperture or ISO may be necessary.
So, does a video camera have a shutter? Yes! But it operates differently than in still photography.
The electronic shutter on video cameras controls how long the sensor is exposed based on set frame rates. While you cannot manually adjust the exposure time like in still photography, other settings such as aperture and ISO can be adjusted to control how much light enters your camera’s sensor. And remember, adjusting your shutter speed can affect motion blur and overall image sharpness.
