Shutter, in photography, device through which the lens aperture of a camera is opened to admit light and thus expose the film (or the electronic image sensor of a digital camera). Adjustable shutters control exposure time, or the length of time during which light is admitted.

The second type of sensor is called CCD and is mostly found in high-end and professional video or cinema cameras. It uses what’s called a global shutter to avoid any distortion in movement. That means it captures a scene all at once so you’ll see no lags in any motion in your frame.

EOS cameras feature a type of mechanical shutter called a focal plane shutter. The camera’s sensor is set at the focal plane – this is where rays of light from the lens come to a focus. The focal plane shutter is positioned immediately in front of the sensor. The shutter has two opaque metal blinds set across the width of an opening. Each blind is made up from a series of metal blades which can overlap.

Rolling shutter distortions are acceptable for video and cell phone selfies. But not for a high-end DSLR. So these use a mechanical shutter and clear all the rows at once. Every pixel is exposed simultaneously, or at least as simultaneously as that mechanical shutter will allow.

When the camera fires, the shutter opens and fully exposes the camera sensor to the light that has passed through your lens. After the sensor is done collecting the light, the shutter closes immediately, stopping the light from hitting the sensor.

A camera shutter is the part of the camera that allows light through to the mirrors, lenses, or prisms of the inner workings of a camera, for a determined amount of time. Without the shutter, images could not be captured by cameras, and light, instead, would infiltrate the lenses and would result in blank media.

The shutter in your X Series camera has a simple job to do: open long enough for light to make a picture, then close again. But your camera actually has two types of shutter – one mechanical, the other electronic – and both have their advantages and disadvantages.

A fast shutter speed creates a shorter exposure — the amount of light the camera takes in — and a slow shutter speed gives the photographer a longer exposure. “Shutter speed gives you two things. One, it lets you freeze time,” author and photographer Jeff Carlson explains.

Shutter count is the amount of photos that your camera has taken. It’s an important number that indicates the life expectancy of your camera. It’s a mechanism that flips a DSLR’s mirror out of the way, built from tiny and delicate parts.
