Aperture Priority is a popular shooting mode found in most modern digital cameras. It allows photographers to take control of the aperture setting while the camera determines the optimal shutter speed for a properly exposed image.

This mode is highly versatile and offers photographers greater creative control over their photos.

In this guide, we will explore the ins and outs of using Aperture Priority effectively to enhance your photography skills.

Understanding Aperture

Aperture refers to the opening in the lens through which light passes to reach the camera’s image sensor. It is represented by an f-number, also known as the aperture value or f-stop. The lower the f-number, such as f/1.8, the wider the aperture, allowing more light to enter the camera. Conversely, a higher f-number, such as f/16, indicates a narrower aperture, resulting in less light reaching the sensor.

Benefits of Aperture Priority Mode

Aperture Priority mode offers several advantages to photographers, making it a valuable tool in various shooting situations. Let’s explore some of its key benefits:

Control Depth of Field

One of the primary advantages of Aperture Priority mode is the control it provides over depth of field. Depth of field refers to the range of sharpness in an image, from the foreground to the background. By adjusting the aperture, you can manipulate the depth of field to achieve either a shallow or a deep focus.

A shallow depth of field, achieved with a wide aperture (low f-number), creates a blurred background, while the subject remains in sharp focus. This technique is commonly used in portrait photography to isolate the subject from distracting backgrounds.

On the other hand, a deep depth of field, achieved with a narrow aperture (high f-number), ensures that both the subject and the background are in sharp focus. This technique is often employed in landscape photography to capture intricate details throughout the scene.

Creative Effects

Aperture Priority mode allows photographers to experiment with various creative effects by manipulating the aperture settings. Different apertures can produce unique characteristics in the image, such as bokeh, which refers to the aesthetic quality of the out-of-focus areas.

Wide apertures (low f-numbers) create a shallow depth of field and pleasing bokeh, perfect for highlighting a subject against a soft, dreamy background. Narrow apertures (high f-numbers) result in a larger depth of field and less pronounced bokeh, making them ideal for capturing detailed landscapes or architecture.

Low-Light Photography

Aperture Priority mode is particularly useful in low-light situations where a fast shutter speed is required to avoid camera shake. By setting a wide aperture, more light can enter the camera, allowing for faster shutter speeds without compromising image quality. This feature is especially beneficial when shooting handheld in dimly lit environments or capturing fast-moving subjects.

Setting Aperture Priority Mode on Your Camera

Now that we understand the benefits of Aperture Priority mode, let’s explore how to set it up on your camera.

  1. Turn on your camera and navigate to the shooting mode dial. Look for the “A” or “Av” symbol, which represents Aperture Priority mode.
  2. Rotate the dial to select the Aperture Priority mode. Your camera may have a specific button or dial dedicated to this mode.
  3. Once you’ve selected Aperture Priority mode, your camera will take care of determining the appropriate shutter speed to achieve a properly exposed image.

Selecting the Aperture Value

After setting Aperture Priority mode, you can now choose the desired aperture value. The availability of aperture values may vary depending on your lens and camera model.

To select the aperture value:

  1. Look for the aperture control dial or buttons on your camera.
  2. Rotate the dial or press the buttons to adjust the aperture value. The changes should be visible in the camera’s viewfinder or LCD screen.
  3. Experiment with different aperture values to achieve the desired depth of field or creative effect in your photos.

Adjusting Other Settings

While Aperture Priority mode primarily focuses on controlling the aperture, it’s essential to understand how other settings interact with this mode to achieve optimal results. Here are some key settings to consider:


ISO determines the camera’s sensitivity to light. In low-light situations, you may need to increase the ISO to maintain proper exposure. However, higher ISO values can introduce digital noise into your images. It’s best to keep the ISO as low as possible while ensuring a well-exposed image.

Shutter Speed

In Aperture Priority mode, the camera automatically adjusts the shutter speed based on the selected aperture value. A wider aperture allows more light to enter the camera, resulting in faster shutter speeds. Conversely, a narrow aperture restricts the amount of light, leading to slower shutter speeds.

Exposure Compensation

Exposure compensation allows you to adjust the overall exposure level of your image. If you find that your images are consistently overexposed or underexposed, you can use exposure compensation to correct the exposure by increasing or decreasing the compensation value.

Using Depth of Field to Enhance Your Photos

One of the most powerful techniques you can employ in photography is utilizing depth of field to enhance your images. By controlling the aperture, you can guide the viewer’s attention and create visual impact. Here are a few tips for effectively using depth of field:

  1. Portraits: Use a wide aperture (low f-number) to blur the background and draw attention to the subject’s face. This technique creates a pleasing separation between the subject and the surroundings.
  2. Landscapes: Use a narrow aperture (high f-number) to capture the intricate details of a landscape, ensuring that both the foreground and background elements are in sharp focus.
  3. Macro Photography: Macro photography often requires a narrow aperture to achieve a sufficient depth of field due to the close focusing distances. This ensures that the subject is entirely in focus, revealing its intricate details.

Capturing Creative Effects with Aperture Priority

Aperture Priority mode allows photographers to experiment with various creative effects. Here are a few techniques you can try:

  1. Bokeh: Set a wide aperture (low f-number) and focus on a subject in the foreground. The shallow depth of field will create a beautiful, blurred background with pleasing bokeh.
  2. Starbursts: Narrow apertures (high f-numbers) can create starburst effects around bright light sources, such as streetlights or the sun. Position the light source just outside the frame and use a narrow aperture for this effect.
  3. Motion Blur: Use a narrow aperture (high f-number) and slow shutter speed to capture motion blur. This technique works well when photographing moving subjects, such as flowing water or moving vehicles.
