360-degree camera makers change direction


Instead of having to frame a picture or point the lens in the right direction, a 360-degree camera can instantly capture the entire scene. Viewing the right picture in the right way can feel like teleporting to another place.

The “spherical” format also opens up new creative possibilities, such as the Instagram-friendly trend for “tiny planet” pictures that shrink a panorama into a distinctive orb. Combining the images of two fisheye-style lenses into a single “spherical” photo or video can create an entirely new kind of selfie, because the photographer can always be in shot.

When I first discovered affordable 360-degree cameras a couple of years ago, I ran out to buy one of my own. But it has spent more time in a desk drawer than in my pocket and I do not seem to be alone in this. Despite the potential for fun and distinctive photography, 360-degree cameras are still struggling to break into the mainstream.

It isn’t for a lack of support from the big guns of Silicon Valley. Popular social apps such as Facebook and YouTube have supported 360-degree videos for a while now, though momentum has been slowed by the limited take-up of virtual reality headsets. At the Consumer Electronics Show last month, new entrants continued to launch 360-degree cameras, but even if the hardware is improving, much of their accompanying software remains sub-par.

Price, at least, is becoming less of a barrier. These devices started to become more affordable with the arrival of the Ricoh Theta S and Samsung’s Gear 360 a couple of years ago, which both cost around $350 when launched. Older models of the Gear 360 can now be bought for under $100 — a bargain for Galaxy smartphone owners but a price which rather suggests someone is trying to shift excess inventory.

The latest developments suggest that manufacturers think picture quality and video resolution are the main things holding 360-degree cameras back.

Ricoh recently launched a new Theta V, which shoots video in 4K (also known as ultra high definition). Yi, the Chinese company best known for its affordable yet capable GoPro clones, has gone even further with its 5.7K VR camera. Both cost around $400.

In my testing, these offer meaningful improvements in quality over the last generation of 360-degree cameras, especially in video output. 4K video is more-or-less essential if you are watching inside a VR headset, where the pixels become very noticeable in lower-resolution pictures.

But while the images are better, there are still some usability barriers to making 360 degree photos as easy as snapping a regular shot.

To get the highest resolution 5.7K resolution video out of the Yi 360 camera, you must connect it to a Windows PC to stitch together the two lenses’ image files into a sphere. While 4K can be processed “in camera” — meaning all the stitching is done before you download the images — relying on a PC is something most of us left behind when we swapped our point-and-shoot cameras for a smartphone app.

The latest developments suggest that manufacturers think picture quality and video resolution are the main things holding 360-degree cameras back.

The Theta V uses in-camera processing and, for the most part, its stitching is pretty seamless (other 360-degree cameras sometimes leave a blurry line where the two fisheye cameras overlap).

But the wireless transfer to a paired smartphone of even a few minutes’ worth of 4K video can take quite a while and consumes a lot of space in your phone’s memory. The Theta V itself has 19GB of internal memory, which is quickly gobbled up by about 40 minutes of 4K video.

While both the Yi and Ricoh cameras eliminate many of their predecessors’ shortcomings, there is still one big question that they fail to answer: knowing when to shoot in 360 at all. While it is useful on holidays or at spectacular sights, I have found it hard to find regular reasons to pull my 360-degree camera out of its drawer.

So perhaps the most interesting new 360-degree camera to launch lately is one which de-emphasises spherical images altogether.

The big innovation from Rylo, a start-up founded by former Apple and Instagram employees, is not in the hardware but its software. Rylo’s $500 device is about the size of a GoPro action camera (much smaller than the Theta or Yi 360) but with a fisheye lens on both sides. Although this is capable of producing spherical video, the clever bit is how its app turns the footage into a traditional “flat” rectangular video.

Firstly, by shooting all-around footage, Rylo can stabilise the video incredibly well, using a combination of computer vision software and the camera’s motion sensors.

On a recent trip to Arizona’s Canyon de Chelly (a bit like a mini Grand Canyon), I took a very bumpy Jeep tour along its sandy floor. As we stared up at the canyon’s spectacular sandstone walls, I held the Rylo out of the window of the car as we rolled over the uneven terrain. The video, though, was as smooth and stable as driving on asphalt — only the rolling roof of the 4×4 hinted at what was really going on.

Rylo’s second trick is that it is a computerised camera operator, able to follow a person or object no matter where they move in front of the two lenses. The computer vision software does the framing and the tracking for you so that your dog, child or mountain-biking friend is always in shot, selected simply by tapping on them in Rylo’s app.

I found this worked better on people than parts of the scenery as we drove through the canyon, but the effect still makes it infinitely easier to turn 360-degree footage into something that can be easily watched on a flat screen. Other settings in Rylo’s app allow for instant creation of “tiny planet” videos as well as a “front back” mode that put the two lenses’ output side by side in a traditional frame.

Lastly, Rylo has another secret weapon that I wish every 360 camera would copy: a cable for downloading images directly to a smartphone, which is much faster and more reliable than the WiFi or Bluetooth transfers that Ricoh or Yi use.

Rylo’s powerful stabilisation and tracking capabilities are still most useful in sports or action situations where I might otherwise have pulled out a GoPro. But it solves the problem of when to shoot in 360 video by recognising that often it is more interesting to focus on one particular area than survey an entire scene.

If you are still tempted by spherical photography, I do recommend the Ricoh Theta V. However, for an extra $100, Rylo gives you similar 4K 360 video but with a far better app that finally delivers on the promise of a twin-lens camera.
