3D photos: How they work and how anyone can take them


As autumn kicks into loftier gear, nosotros’d similar to invite you to see photography in a whole new light: Through the lens of



3D photos


. This is the commencement installment in a series dedicated to upping your 3D photography skills, regardless of camera experience and skill level.


If you’ve been looking for a fresh mode to share your adventures (down the block or beyond the world), so we’d similar to offer some tips on how to make your own 3D photos really pop on your smartphone and calculator screen, not to mention inside VR headsets such as



Oculus Quest


, Oculus Go, too as headsets on the



Rift platform


. And then, while we can’t live nether the summer dominicus forever, adding a petty depth to your shots is but i mode to capture the season and celebrate the art and craft of seasonal photography.


Hi! My proper noun is Brian Thivierge, and I’m a design director at Facebook. I help various teams at the company build their creative projects through visual storytelling.

I’ve e’er enjoyed experimenting with the cutting edge digital media, so when I got involved with Facebook’s 3D photo projection every bit an early beta tester, I was hooked all over again. In the brusque time they’ve been available, I’ve shot 3D photos in the Sierra, London, Costa Rica, Hawaii, and other places, and I’ve found they capture memories amend than old-fashioned pictures. Each one is full of dimension and life, bringing us closer to the people, places, and things nosotros’d rather not forget.

I hope y’all’ll bring together me as I share some of the tips and tricks I’ve learned along the way.



3D photo essentials

In essence, 3D photo engineering takes the subject in the foreground and measures it confronting any is in the groundwork. This information is then used to create an accurate depth map and, when combined with Facebook’s custom software, gives photos movement and depth when you gyre by them in News Feed. The effect is a little like peeking into a magic window on your computer or smartphone screen. If you’re wearing an Oculus Quest or Oculus Get headset, or a headset on the Rift Platform, 3D photos look like living, breathing museum pieces that answer dynamically to your perspective and movement.


The upshot is a little similar peeking into a magic window on your estimator or smartphone screen.

In recent years, many major smartphone makers have added a dual-lens portrait mode to the cameras in some of their phone models. This setup allows them to take stereo photos and compares the two images to create a crude depth map. Beneath, you can encounter one of the color photos and the grayscale depth map created and embedded into the file. The lighter the colour, the closer information technology is. Information technology’southward pretty amazing how they can get that detail from two cameras sitting less than an inch from each other.

Facebook and so used the gradient to build a 3D model and layer on the colour image. Together with AI systems working in the background,

yous get the amazing 3D photos you see on the Facebook feed today, whether on your telephone, laptop, or in VR.


The nuts of creating your own 3D photos

All y’all demand to get started is a phone capable of generating depth maps, which basically means whatsoever modernistic smartphone with two cameras positioned on the dorsum of the device. Using a dual-lens smartphone is the easiest way to create 3D photos, merely information technology’due south not the simply way to do it, so don’t despair if y’all’re downwards a lens. You can also create 3D photos using an assortment of widely available apps, but I’ll become into that later.

One time you’ve taken a few shots with a dual-lens smartphone, outset a Facebook mail service every bit y’all ordinarily would, so tap the three dots on the upper right of the new post to discover the 3D Photo selection. Depending on your device, this action takes you to your Portraits folder. Lastly, pick the photo you desire to share, add a caption if y’all desire to, and and then postal service away. Using the Android photographic camera app, choose the live focus or portrait choice, depending on your model, to generate a depth map of your photo. You can besides utilise the background blur to simulate a depth of field. Adding background blur can hide the artifacts that 3D processing creates. Experiment with similar photos and varied amount of background blur to see which works best for your shot.


Tips and tricks for deeply cool images

Please notation the data below is largely subjective and should be viewed as guidelines, not rules. They are merely helpful tidbits I’ve collected over the summer, shooting everything including exotic flowers and wild chickens. To commencement, y’all’ll want to observe objects that are mostly static, such as plants, flowers, and architecture. Models, miniatures, and toys are all perfect subjects for 3D photos. Humans and animals work also, of course, but 3D photos tin can get dicey with excessive move in the shot, so ask your field of study to strike a pose.

We’re going to illustrate each tip below with a row of 3 images. The first prototype in each row is a typical 3D photo, just the remaining two depict a carve up 2D shot and relevant depth map to assistance you visualize the different layers picked upwards by the camera.



— Tip 1 —

Look for subjects with a strong, distinct foreground and groundwork elements.

Basically, y’all desire your photo to split evenly amid ii or 3 layers of varying distances.





— Tip 2 —

Depth calculations are typically strongest between 18 inches and 10 feet, but they will work to thirty feet depending on the camera.





— Tip three —

Certain fine details, such every bit wisps of hair or bridge cables, don’t always show upwardly well because depth calculations require greater volume to work best.





— Tip 4 —

Transparent materials and surfaces — for example, glass and water — don’t e’er translate well. Like fine geometry, transparent subjects tend to confuse the depth camera.




— Tip 5 —

Keep nonetheless! The depth camera takes fourth dimension to procedure the shot, so moving subjects and shaky cameras will produce blurry results from inaccurate depth map data.





— Tip six —

If you’re going to shoot a geometric shape of some sort, try not to shoot information technology caput-on; find an angle that makes the most of the 3D issue.





— Tip 7 —

Low light typically doesn’t work. If there are places the camera can’t see, it will guess at the depth and produce wonky results.





— Tip 8 —

Landscapes are tough to shoot, so placing an item (anything volition do!) virtually the footing to capture depth will give you better results.




Departing shots

With 3D photography in its infancy, we’re all still learning how all-time to capture our memories using this new technology. Information technology’s OK if your start round of shots doesn’t wait perfect. Figuring out the right alloy of light, limerick, and subject will take a few attempts, just y’all’ll become there!

Y’all tin can find a number of Facebook groups focused on 3D photos. Endeavor starting with the Facebook 360 group:
