It's a versatile shooting mode in which you take the reins of aperture control while your camera seamlessly manages shutter speed for impeccable exposure. But let's dive deeper: What's aperture?

Aperture Priority Mode, labeled "Av" or "A" on your camera's mode dial, is a versatile shooting mode in which you take the reins of aperture control while your camera seamlessly manages shutter speed for impeccable exposure.

How Does Aperture Priority Mode Work?

Upon selecting Aperture Priority Mode, you take the reins by handpicking your shot's aperture value (or f-stop). Once you have decided on your aperture setting, the camera quickly auto-adjusts the shutter speed to select an exposure perfectly attuned to your available (or ambient) light. If you decide on a wider aperture (meaning a smaller f-stop number), you allow light to flood the sensor, making a shallow depth of field with softly fuzzy, out-of-focus backgrounds.

When selecting a narrower aperture (a bigger f-stop number), the opposite is true. This restricts the light going into your camera, resulting in a deeper depth of field that makes a shaper "zone of focus" from the foreground to the background of your photo.

What Does Aperture Priority Mode Do?

When it comes to photography, Aperture Priority Mode gives you the power to shape one of the exposure triangle's core components— aperture—while turning the keys over to the camera for the rest of the exposure elements (ISO and shutter speed). You control the aperture, and your camera's capable hands are flipped over to auto. 

AP mode becomes your buddy when you want to prioritize the depth of field in your picture and grasp what your aperture actually does. For example, if we were going to take a closer look at portrait photography when you want to simply blur the background, choose a wider aperture (marked by a lower f-stop number). Switch it up, reversing that choice when trying your hand at landscapes. With a deep depth of field, you'll take pictures with sharp clarity across the entirety of the frame.
