APERTURE & DEPTH OF FIELD

How does the aperture affect exposure? A WIDE/LARGE f/stop is a SMALLER number (f/2) = OPENS the aperture for MORE light A SMALL f/stop is a LARGER number (f/22) = CLOSES the aperture for LESS light.

HOW DOES THE APERTURE AFFECT DEPTH OF FIELD? An example of shallow depth of field (large f/stop). . . This photo was taken with an f/stop of f/2. 0. Wanted to really focus on the contrast between the pretty headband the dirty toddler fingers, a large f/stop to really narrow down the depth of field was used. As you can see, the main areas of focus in the picture are the fingers and the jewels on the headband, with everything else in the image much softer. Shutter speed of 1/125 and an ISO of 400. An example of a wider depth of field (smaller f/stop). . . Smaller f/stop of f/10 was used to take this image of the sunset in Hawaii. We wanted the scene to be mostly in focus, and you can see that for the most part the foreground, middle and background of the image are all in focus. Shutter speed of 1/160 and an ISO of 100.

The above photos have the exact same shutter speed and ISO setting (1/250, 400) and only changed aperture. You can see how the larger the aperture (the smaller number) the more light is let in, the smaller the aperture (larger number) the less light is let in.

A comparison of how Aperture setting can affect the Depth of Field of an Image In the photos above all three of settings have been adjusted to achieve correct exposure of the scene (no blown out or over-exposed highlights and good detail in the shadow). By looking at the scene behind the little bear, you can see that in the first image with the larger f/stop (f 1. 4) the background is totally out of focus and blurry. With a slightly smaller aperture we start to see that background come in to focus, and with the last photo that has the smallest aperture (f/16) the background is clearly in focus and you can make out the swings and other detail in the background.

REMEMBER Aperture f/stop numbers & Exposure Small number = more light Large number = less light Aperture f/stop numbers & Depth of Field Small number = Small depth of field Large number = Large depth of field
