Shutter

The size of the opening controls the amount of light that gets through to the camera sensor, and that makes sense, doesn't it? And it also controls how much of your scene from front to back is sharp.

Tip three, shutter speed, what it controls.

Shutter speed determines the time that your camera sensor is exposed to light by the shutter being open.

It's a time measurement that runs from thousandths of a second to whole seconds.

One one-thousandth of a second, easy for you to say, Rick, I do struggle with that, [laughs] is, is a very fast shutter speed.

A fast shutter speed lets in less light.

A slow shutter speed lets in more light.

Shutter speed also decides whether movement in your photo looks frozen or blurred.
