Aperture and Depth of Field

Aperture is the opening in the lens that controls the AMOUNT of light that you allow to enter the camera. It is measured in a thing we call the F number.



As you decrease the size of the Aperture you increase the amount of the picture that is in focus. This is called Depth of field.

Watch the following video for a good explanation of how Aperture works. We'll began shooting in Aperture Priority and doing Depth of Field exercises later in class.

Aperture Priority is when you select the aperture and the camera chooses the corresponding shutter speed. Both modes have advantages, but aperture priority ultimately gives you more control over the overall quality and visual focus of your images. 

Depth of Field is the amount of the image that is in sharp focus

Here is the a link that describes how and when to use Aperture Priority

Here's link that descibes how to take better pictures using Aperture Priority.

Use the Nikons to experiment with Depth of Field around the building. Take pictures with both Shallow and Deep Depth of Field. We'll post them next class.
