Aperture and Depth of Field
The size of the opening to which light passes through the camera lens.

Photos taken with a low aperture let in more light, allowing you to take pictures in situations where there is not much light (like indoors and at night).
A low aperture will also give you a shallow depth of field. You know, the photos where one thing is in focus and the background is blurred?
Canon 50mm f/1.8
f/1.8 1/200 sec
ISO 800
In this photo, the aperture was set to 1.8, a low aperture. One earring is in focus, the rest is blurred.

Canon 24-70mm f/2.8 f/16 1/60 sec ISO 100 In this picture, the aperture was set to 16, a high aperture, allowing everything to be in focus. However, when you take pictures with a high aperture, you need to have a lot of light, like outside during the day. |
Turn the dial on your camera so that you are shooting in Aperture Priority mode. That means that you will be setting the Aperture, and the camera will automatically adjust the shutter speed. The camera will attempt to give you a correct shutter speed so that your photo turns out just right- not too bright, not too dark.
Note: Be sure to keep an eye on your shutter speed as you do this. See the number 125 in the picture above? That number represents the shutter speed. As a general rule of thumb, you don’t really want to let the shutter speed get below 50, unless you have an extremely steady hand. If the shutter speed gets below 50, the camera cannot take the picture fast enough to compensate for the shakiness in your hands, so the picture will be blurry. If the shutter speed is getting low, try using a tripod or table to steady the camera, or lean against a wall, door frame, or tree to steady yourself.
