Understanding Aperture
One of the most significant effects of aperture is its impact on depth of field (DOF). Depth of field refers to the area in an image that appears sharp and in focus. A wide aperture (small f-number) creates a shallow depth of field, resulting in a blurred background and a focused subject in the foreground. This technique is often used in portrait photography, where the subject stands out prominently against a soft, dreamy backdrop.
