How to use Aperture Priority? [Complete Guide]

Before we can comprehend what aperture priority mode is on your camera, we must first define an aperture. The aperture controls how fuzzy or distinct your background appears in a shot.

A bigger aperture of f/1.4, for example, will make your background appear soft. This aperture is ideal for photographing in low-light conditions. A narrow aperture of f/22, on the other hand, will capture more details in the background of your images.

One of the best methods to experiment with different depths of field is via the aperture. With the appropriate aperture, you can make your images pop out much more than if you ignore the setting. This is why aperture priority mode is essential. It broadens and expands your photographic possibilities.

What is Aperture Priority?

Aperture priority is a camera option that lets you select the aperture, white balance, and ISO. Your shutter speed, on the other hand, is unaffected by aperture priority. Instead, your camera will continue to adjust the shutter speed in response to variations in lighting. You cannot manually modify your shutter speed when using aperture priority.

Why is aperture priority so beneficial? It provides you complete control over your camera’s most crucial settings. The only way to have complete control over your aperture is to go into full manual mode. Before tinkering with any other adjustments, make sure your aperture is set correctly.

Another significant benefit is that aperture priority mode is simple to utilize. Manual mode is a little slower, requiring more time to properly set up for each image as the light changes. When used correctly, aperture priority mode provides faster access to ideal camera settings than manual mode.

For a practical example, suppose you want to use an aperture of f/5.6. You want to take a lot of shots with the same aperture, but the light isn’t consistent. Rather than altering all of your settings as the light changes, switch to your camera’s aperture priority mode, select f/5.6, and let your camera adjust all other crucial parameters on its own. Aperture priority literally prioritizes the aperture; keep your f/5.6 throughout the entire shooting session.

How do I use Aperture Priority mode?

It’s as simple as flipping the dial on your camera to use aperture priority mode. You want to set your dial to A or Av. The next step is to manually enter your aperture into the camera. This refers to the f-stop setting that you will employ. Keep in mind that after you’ve manually selected the aperture, your camera will never change it. You will have to alter it each time you need a different depth of field.

Once you’ve manually set your f-stop, it’s time to select the appropriate exposure compensation. You don’t want to overexpose the characteristics in your photograph. Normally, the exposure compensation will be between -0.3 and -0.7. To get the appropriate exposure, exposure compensation modifies the shutter speeds selected by your camera.

The final step is to select your ISO. Unless you’re in a special situation that necessitates a really high ISO, it’s best to adhere to the base ISO, which is often 100 on modern cameras.

As you can see, using aperture priority is really simple. It’s also quite fast. When working on landscape photography, it’s simple to select the appropriate aperture, a fair exposure correction, and then your base ISO. It only takes a few seconds before you’re ready to start shooting.

Furthermore, it makes no difference what happens to the light. Even if you end up shooting in and out of shadows or encountering cloud issues, your settings are excellent. Even though cloud systems can have some issues at times, they have made every function easier. They have brought automated user management solution for schools and organizations, thus reducing tasks and saving time. All of it will be worked out by your camera on its own.

When should I use Aperture Priority mode?

Aperture priority mode is such a versatile and adaptable shooting mode that you can probably utilize it at least 95% of the time, regardless of genre. This means you can use aperture priority mode in almost every situation.

The only time you should avoid using aperture priority mode is when photographing the night sky or the Milky Way. In this instance, automatic exposure will produce the worst results possible. Your photographs will be overly dark and inconsistently exposed. We recommend using manual mode while photographing stars, in extremely dark environments, or when attempting to capture a large panorama.

Furthermore, in aperture priority mode, your shutter speed is always limited to a maximum of 30 seconds. You must also switch to manual if you intend to use your camera’s bulb and shoot long-exposure shots.

The same is true for flash photography. Aperture priority will not offer you enough control over the flash to balance it with the ambient light. For example, any macro photography you do with the flash must be done in manual mode.

Aperture priority mode is ideal the rest of the time. If you’re shooting in daylight, sports or wildlife, or portraiture, aperture priority mode is great.

Aperture Priority & Handheld Mode

At night and in low-light settings, you can still use aperture priority mode. It’s not perfect for photographing the night sky or stars, but it’ll suffice when it’s dark outside. When it gets dark, though, there is something you should know about aperture priority and handheld mode.

Because aperture priority mode forces your camera to set the shutter speed on its own, it will automatically use longer shutter speeds in low-light situations. When the lights go out, for example, your camera may select a shutter speed of up to two seconds. This will be a nightmare if you’re filming in handheld mode. A shutter speed of two seconds is too long to hold the camera without jerking it slightly.

However, there are two solutions. A tripod can be used. With a tripod, aperture priority mode performs admirably. Another option is to boost your ISO. Set your ISO to 800 or 1600 instead of the default setting. This will force your camera to use a faster shutter speed to compensate for the increased ISO. Then you can resume photographing without a tripod.

Aperture Priority & Automatic ISO

When you go to auto ISO mode, there are a couple more options that we haven’t covered yet. Auto ISO includes a shutter speed restriction. This does not change the shutter speed for each photo. Instead, it simply limits the shutter speed so that you don’t unintentionally set your shutter speed to 2 seconds when shooting in aperture priority mode. A more secure value would be 1/100. This will keep your images from being fuzzy as a result of a fast shutter speed.

However, if you’re capturing action images, you might want to reduce the shutter speed to 1/500 or even 1/1000. The shutter speed is still set automatically, but it will be limited to reasonable bounds.

Aperture Priority vs. Shutter Priority

You may be wondering what the difference between aperture priority and shutter priority is at this stage. The main distinction here is that the aperture priority mode will keep your aperture fixed while changing your shutter speed automatically. This is perfect for photographers who desire a consistent depth of field in their images.

However, if you use shutter priority mode, your shutter will be the one that operates at a fixed speed. Everything else shifts. If you’re taking action photography, this is the mode to employ.

Experimenting With Different Apertures

If you’re a newbie who feels overwhelmed by aperture priority mode, there’s a proven way to learn it. Experiment with different apertures to see what works best for you. Because you don’t have to move between shutter speeds and ISO values while using aperture priority, you can easily modify your aperture. Begin with a large aperture and work your way down, taking shots of the same topic and determining for yourself which aperture works best for which target.


Aperture priority mode is a favorite of professionals and one of the most simple options for beginners. If you’re new to photography and don’t yet understand manual mode, aperture priority is a terrific option. It is a more efficient method of obtaining ideal settings. Aperture priority can also be used to simplify the intricacies of photographing.

Having said that, aperture priority should not be used as a crutch for individuals who are overwhelmed by the other settings. Make sure you understand your aperture, exposure, ISO, and depth of field by taking a lot of shots with aperture priority! After that, try with full manual mode.
