Interested in learning how to take professional-looking photos with your phone?

Whether you’re taking family pictures that will last a lifetime or you want to step up your Instagram game, use portrait mode to achieve shots that look similar to those taken with a DSLR camera.

What is portrait mode?

Portrait mode is a phone camera feature that keeps objects in the foreground focused while blurring the background. Apple dubbed the feature “portrait mode” in 2016 with the release of iOS 10.1. In photography, this depth effect is called bokeh.

Which iPhones have portrait mode?

1. iPhone 7 Plus
2. iPhone 8 Plus
3. iPhone X
4. iPhone XS
5. iPhone XR
6. iPhone XS Max

Portrait mode is only available on iPhones that have a dual-camera. A large aperture makes the background out of focus by using a narrow depth of field. This option allows end users to use other emerging technologies, such as posting 3D photos on Facebook.

Androids also have portrait mode, or a version of it. Some of these phones even offer similar effects for selfies.

How to use portrait mode

You can use portrait mode natively on iPhones and Android devices. Plus, with third-party apps, you can create images that have a similar bokeh effect.

iPhone portrait mode

1. Open the camera app.
2. Swipe through the various effects along the bottom above the shutter button and select “Portrait.”
3. Using portrait mode, your iPhone’s camera will automatically focus on your subject in the foreground.
4. Aim your camera at your subject. It must be within two to eight feet from your phone. If you aren’t within these parameters, you will get “move further away” and “move closer” prompts accordingly.
5. When portrait mode is in effect, a yellow box will appear on the screen. For iPhone 8 Plus and newer models, the box will read “natural light.” For the iPhone 7 Plus, “depth effect” will appear in the yellow box.
6. If you see the “natural light” box, you can adjust lighting as necessary. Swipe through additional options such as studio light, contour light, stage light, and stage light mono.
7. Snap your picture by pressing the shutter button.

I used an iPhone 7 Plus to capture this moment with my dog, Wrigley. Notice how she’s crisply outlined, down to the individual hairs on her ears.

On later iPhone models, you can continue to adjust a portrait mode photo after you’ve taken it. Click “edit” to change the amount of background blur and add studio lighting effects. You can also remove the portrait mode effect from the photo altogether.

Portrait mode for Android

The various devices have different interfaces, but here are the general instructions for using portrait mode on Android.

1. Open the camera app.
2. Select the menu button or swipe to choose the portrait option.
3. Point your phone at the subject and take a picture with the shutter button.
4. With some models, the blur is applied after the photo is taken.

My brother used a Google Pixel 3 to get this shot – the foreground is so clear you can even see the distinction between cream and coffee.

In portrait mode, the Google Pixel 3 takes a photo with a blurred background and plus saves an original version. You can also make a few tweaks to the shot with the “edit” option, including adjusting the depth, level of blur, and focal point.

Portrait mode apps

If you have an older model phone, you can create photos that look just like portrait mode. It just requires a bit more editing in third-party apps.

Fore Photo

This free app allows you to mask out a subject to feature and blur the background of any photo. It’s not an exact science, but it works well for big, bulky objects. You can change the brush size as well as the level of blur to apply.

FabFocus

This paid app offers a few additional options, like facial recognition to automatically blur the background behind an identified face. It’s more complicated than other options, but it does offer the best features to create portrait mode-like pictures.

Portrait mode tips

These general photography tips will take your portrait mode photos to the next level.

Distance matters

The larger the distance between your subject and your intended background, the better your photos will turn out. If your subject is up against a brick wall, it will hardly be blurred out in portrait mode because the camera will struggle to focus.

Stay still

Of course, you as the photographer should try to be still. But for the best shots, your subject should also try to stand still for the clearest images.

Check the background

Make sure that your background is free of distractions, like bright-colored objects. The phone’s camera can get confused. On top of that, bright colors can pull focus, drawing the eye to the blurred mystery object.

Follow the light

Bright, natural light makes for the best photos, period. Light and its resulting shadows give the camera a better indication of what to blur and where. This creates crisp, clean pictures.

Use a filter

Great lighting isn’t always readily available, but that doesn’t mean you can’t get great shots. Create the illusion of light with filters. When coupled with portrait mode, filters can completely change and customize your image.

Say “technology”

Now you can take high-quality photos using only your phone! If you want to learn more about photography, check out the top photo editing software for 2019.

What is portrait mode and which phones have it?

There’s a good chance you use your smartphone to take pictures and capture video. There’s a relatively new feature a lot of smartphones have called portrait mode, and it can up your photography game big time if used properly. However, you might not know what portrait mode is or how it’s used. So what is portrait mode exactly? Good question.

Let’s examine portrait mode in an effort to separate the marketing jargon from the facts. We’ll also give you a list of current smartphones with portrait mode so you can make informed buying decisions.

Let’s get started!

What is portrait mode?

Portrait mode is a term used to describe the artificial bokeh (BOH-kay) effect produced by smartphones. Bokeh is a photography effect where the subject of a picture is kept in focus while the background falls out of focus. By using portrait mode to create a bokeh effect, you can take dynamic photographs which look more professional.

Years ago, if you wanted to take pro-quality photographs, you’d need a DSLR or analog camera. Nowadays, even mid-range smartphones can deliver exceptional results.

However, one of the biggest historical limitations of smartphone photography had been the ability to simulate depth using bokeh. Without high focal lengths, large sensors, and control over focus, even high-end phones couldn’t create the blurred background effect.

Recently, though, advancements in computational photography — as well as the introduction of dual-lens smartphone cameras — have brought artificial bokeh to phones. Most smartphone manufacturers refer to this effect in marketing material as portrait mode. Additionally, the setting in most camera apps that creates bokeh is usually called “Portrait Mode” or simply “Portrait.”

Portrait mode examples

You know what they say: a picture is worth a thousand words. With that in mind, let’s check out some examples of photographs using portrait mode to create a bokeh effect. Below you’ll find a gallery of pictures captured with a variety of smartphones, all using the portrait mode setting.

As you scroll through the photos, pay attention to the backgrounds:

Portrait mode makes the subject of your photo really pop. Since the background is blurry, your eyes naturally gravitate towards the non-blurry section of the picture. It can be a powerful technique when used properly.

However, the images above are not “real.” The bokeh effect is not produced using just the smartphone’s lens (or lenses). Instead, the smartphone’s processor, software, and camera hardware work together to apply the bokeh effect to a non-bokeh image.

Because you’re relying on a computational algorithm to create portrait mode effects, results can vary. Check out the photo below where the phone’s portrait mode filter gets confused and can’t get the effect right:

For some reason, the algorithm determined the edge of Lanh’s glasses was part of the background and thus blurred it out. If you were using a DSLR to take this photo and produced the bokeh effect using the lens itself rather than software, this problem wouldn’t happen.

However, when you’re using a smartphone to create a bokeh image, you don’t have to lug around a large DSLR, which is certainly advantageous. With that in mind, don’t let a few faulty images deter you. The algorithms responsible for portrait mode are only getting better, so problems will become less and less of an issue going forward.

Which phones support portrait mode?

Hopefully, you now have a better understanding of portrait mode and how bokeh effects can make your photos better. However, how do you know if your smartphone supports the feature?

In general, most phones with at least two lenses paired together can produce portrait mode pictures. Some phones can produce the bokeh effect with just one rear lens (the Google Pixel 2 and Google Pixel 3 being the most notable examples), and some dual-lens phones can’t do portrait mode (like the LG V30). However, if a new phone has two lenses on the back, it’s a safe bet it does portrait mode shooting.

Some smartphones are now shipping with two lenses on the front, too. This allows for portrait mode pics in selfie mode. However, there are phones with a single selfie lens that can also do portrait mode.

Below, we’ve compiled a list of recent smartphones that have portrait mode abilities with the rear camera at least. This list is not completely comprehensive in that there are likely other phones out there with portrait mode not included here, but we did include all the most popular releases.

There are also numerous ways to “hack” your phone to get portrait mode when it is not offered by the original OEM. However, we are not going to cover that here.
