Over the weekend, I’ve been testing the powerful Kandao Obsidian R, a professional 3D 360 camera with 8K 3D 360 resolution and live streaming capability (no I don’t own it – yet 😉 – it’s just a loaner).  Here are my first impressions and a tutorial for using it.

This year, Kandao launched three professional 3D 360 cameras: the affordable Obsidian GO (4K 3D 360 video, $2,499), the high-speed Obsidian S (6K 3D 360 up to 50fps or 4K 3D at 120fps; $6,999) and the high-resolution Obsidian R with 8K 3D 360 ($6,999).  Kandao cameras and stitching software feature cutting edge 360 video technologies such as depth-aware stitching, Kandao is working on generating a depth map and even video with 6 degrees of freedom.

Here are its specifications:
– six lenses
– six 12mp Sony BSI CMOS sensors
– Aperture: f/2.2 (Obsidian S) or f/2.8 (Obsidian R)
– video resolution: 5760 x 5760 @ 50fps (Obsidian S) or 7680 x 7680 @ 30fps (Obsidian R)
– photo resolution: 5760 x 5760 (Obsidian S) or 7680 x 7680 (Obsidian R)
– live streaming: 4K3D or with servers, up to 6K3D or 8K3D
– audio: 6 microphones, has stereo input jack and supports synchronization with Zoom H2N for spatial audio
– ISO 100 to 3200
– Shutter speed: 1/6400 to 60 seconds
– Dynamic range: 10 stops for video or 12 stops for photo
– powered by a single Ethernet cable (for power and data), or adapter, or two Canon LPE6 batteries
– 14.5cm diameter x 9.3cm height
– 1.1 kg

Obsidian R is AFAIK the most affordable 8K 3D 360 camera on the market (by comparison, the Yi Halo with 8K 3D 360 is about $15,000, and the Z Cam V1 Pro with 7K 3D 360 is $40,000).  The Obsidian is sometimes compared with the Insta360 Pro, which can shoot 8K in 2D or 6K in 3D.  Obsidian’s proponents point, among other things, to its advanced stitching technology and its high image quality.  Originally, it was announced to be $10,000, which is beyond most photographers’ budgets, but the final price was set at $6,999, which put it just within reach of many professionals.

Kandao sent me a loaner Obsidian R for testing for a couple of weeks.  The Obsidian came in an aluminum hardcase with custom foam cutouts.

The case included:
– the Obsidian camera
– six 64GB Micro SD cards (if you want to use your own, U3 cards are recommended)
– USB 3.0 card reader
– sync control cable for Zoom H2N
– an ethernet cable
– lens pen and microfiber cloth
– an alternate cover with coldshoe
– a hotshoe to 1/4-20 adapter
– bubble level
– hardcase with shoulder strap
– dustbag for the hardcase
– optional: POE (power-over-ethernet) power adapter and power cord

The package does not include a battery. However, it uses two Canon LPE6 batteries for Canon DSLRs that many professionals already have.

The Obsidian is smaller than I expected, although actually it is almost the same diameter as the Insta360 Pro, which is not unexpected because they both have six lenses and the interpupillary distances are about 63.5 mm, the same as the average distance for people in order to make the 3D effect appear natural.

The Obsidian R’s body is polycarbonate with copper trim, and feels very solidly built, reminding me of the build quality of the Nikon D3 that I used to have.  There is a small copper plate below each lens identifying the lens number.  The Obsidian S is similar except that instead of copper trim, it has a striking red trim, and the lens plates are black.

The Obsidian uses six Micro SD cards, which are stored below each lens, secured by rubber covers.

The bottom of the Obsidian has several connectors: the Ethernet jack for data or power, a 12V DC adapter input jack, an audio sync jack, and two tripod holes with a third hole for the anti rotation pin on some tripods.

How to setup the Kandao Obsidian

There are three ways to power the Obsidian:
– 12V adapter
– Power Over Ethernet cable, or
– use two Canon LPE6 batteries.

For Power Over Ethernet, there is an optional POE power supply that looks like an AC adapter except that it has two ethernet jacks instead of a standard AC adapter cable.  Like a standard AC adapter, it has a power plug.  Then one ethernet jack goes to your network, while the other jack connects to the Obsidian, providing it with both data and power.

For Canon batteries, the battery compartment is on top of the camera, making it easy to access even when the Obsidian is mounted on a stand.  The battery compartment cover is easy to remove thanks to a couple of small springs that raise the cover slightly when unlocked.  There are small spring-loaded clips to hold the batteries in place. When you push the clip away, there’s another spring to make it easier to remove the battery.

Interestingly, there is a second battery compartment cover included that has a cold shoe on top.  There is an included hotshoe to 1/4-20 adapter designed to make it easy to mount a Zoom H2N securely over the Obsidian without being seen in the shot.  The cold shoe is a unique and very useful feature, and can also be used to attach the included bubble level or perhaps an LED light.

The Obsidian can be attached to a tripod or light stand with 1/4-20 or 3/8 stud.

How to shoot with the Kandao Obsidian

After holding down the power button, the Obsidian starts up relatively quickly in about 10 seconds (that already includes the time you hold down the power button).

There are four ways to shoot with the Obsidian:
– on-camera buttons
– Wi-Fi
– Bluetooth
– desktop control (for live streaming).

On-camera buttons: to record a video, you can simply press the video button.  It starts recording after a couple of seconds. Press it again to stop recording.

The photo button works for both time lapses and for self-timer photos.  To take a photo, you press the button.  After a couple of seconds, it takes the first photo.  It will then keep taking additional photos every 10 seconds (this interval can be adjusted in the remote app – see below).  To stop shooting, you press the button again.

Wi-Fi: the Obsidian can be controlled remotely via Wi-Fi but it doesn’t have a built-in Wi-Fi antenna. Instead, you need to connect it via the Ethernet cable to a wireless router (I used a Huawei HiLink router powered by a portable powerbank).  Download the Obsidian app (Android or iOS), and connect your smartphone Wi-Fi to the wireless router’s network.  Launch the app and tap “Connect.”  In my case, it worked every time.

You will see a live preview of each individual lens. You can switch shooting modes from photo, video, to time lapse.

The Obsidian app has extensive controls including:
– standard, flat, or log mode
– auto, manual, ISO priority, Shutter priority. ISO range is 100 to 3200. Shutter speed 1/6400 up to 60 secs in manual mode.
– shutter angle (amount of motion blur based on ratio of shutter speed to the frame rate)
– exposure synchronization (whether to use the same exposure for all cameras).  This is the sun icon at the top.
– white balance synchronization (whether to use the same white balance for all cameras).  This is the half moon icon at the top.
– color temperature and tint
– video bitrate (up to 60mbps per lens for Obsidian R)
– video codec (H.264 or H.265)
– time lapse interval (from 4s to 60s)

Bluetooth: The Obsidian can be controlled wirelessly via Bluetooth, and it won’t require an external router.  It works just like Wi-Fi except that there’s no live preview.  To use this option, both the firmware and app must be updated.  Simply turn on the Obsidian, launch the app on your phone, and select “connect with Bluetooth.”  It will show the nearby Obsidians, and you tap on the one you want to connect with.  Within a few seconds, it will show you the main shooting screen, the same one as for Wi-Fi except that there is no preview shown.

Desktop control: You can control the Obsidian through the Kandao Studio app for Windows.  To use this option, the PC and the Obsidian both have to be connected to the same router.

How to stitch

Kandao Obsidian includes Kandao Studio, their stitching software for Windows (no Mac version available),  which is very easy to use but does require a powerful computer.  The requirements depend on your desired resolution and whether you are using fast stitching or high quality stitching, and can be as low as 8GB RAM and 2GB GPU memory (for 1920 x 1920 video with fast stitching) to 24GB RAM and 10GB GPU memory (7680 x 7680 with fast stitching and GPU accelerated stitching).  For high quality stitching, you’ll need 24GB RAM and a graphics card with 8GB memory, such as a GTX 1080.

Transferring files

There are several ways to transfer the files from the camera to the PC.  The easiest way is to connect an Ethernet cable from the Obsidian to the router used by your PC.  You then launch the Kandao Studio app, and go to Tools… Export to Camera, which will allow the Studio to copy the files from the camera to your hard drive.  As long as you don’t rename the files, they won’t get mixed up.

Studio will recognize related photos or videos and will only show you the primary name of the file and not the six files for each photo or video.  But if you choose to use a 3rd party stitcher it helps to know the file naming convention.  The file names for the photos and videos start out with a prefix 001, 002, etc. and the individual lens files for the same photo or video have the same prefix.  The suffix is 01 o 06 to help you identify which lens the file came from.

Stitching

Stitching with Kandao Studio is as easy as it gets.  You only have simple buttons, sliders, and checkboxes on the right side.  It can be literally a one-click process.  There is no need to identify control points or make manual adjustments. The interface for photos and videos are almost is the same, except that for videos, you have the option to trim the video by setting the in and out points.  The easy interface means that you’ll be able to focus on the creative aspect of creating videos instead of being stuck with tedious stitching.

I don’t have samples worthy of sharing yet but I will be shooting with the Obsidian over the weekend and will provide samples next week, together with a video tutorial and review.  If you have particular questions, please let me know in the comments.
