  • Smart Interactive Drone
  • 720p Videos
  • 5MP Photos
  • Takeoff and Landing from Your Hand

Built in partnership with Ryze Tech, the DJI Tello Quadcopter (2019) is designed to be a fun and educational quadcopter drone. The 2019 edition features a larger and more robust form factor and includes a micro-USB cable. Its Intel processor enables it to perform exciting aerial tricks on a whim, all through smartphone control. Download the free Tello app and get going, with intuitive controls for entertaining flying maneuvers. The included battery will power up to 13 minutes of flight on a full charge.

At the front of the Tello is a camera capable of streaming 720p video back to your smartphone and capturing 5-megapixel photos in flight. The intelligent flight processor can coordinate camera movements for some custom shooting angles. The vision positioning system uses a downward-facing camera to ensure stable hovering when desired.

The Tello also includes four pairs of propellers and propeller guards. Multicolored top plates are available separately to customize the look of your drone.

Great for Beginners

Flying the Tello drone is easy. Just pull out your phone with the app and begin flying by literally tossing the drone in the air. For those feeling adventurous, the Tello is VR headset-compatible for FPV flying. Swipe on your smartphone to activate 8D flips for slick aerial moves. If you want more tactile control, connect a Bluetooth controller to your smartphone and fly more traditionally.

Built-In Camera

The Tello can transmit 720p video or 5MP photos back to your smartphone from up to 330' away using its dual antenna array. Electronic image stabilization helps keep your photos and videos steady. Coordinated flight moves let you capture short videos with 'circle', '360', and 'up-up-and-away' styling for a professional touch.

Use Tello to Learn and Create

Ryze Tech made Tello programmable with Scratch, an MIT-developed visual coding system which allows kids and teens to learn the basics of programming while having fun. If you're a more advanced user, you can also develop software applications using the Tello SDK.

Safety Features

Tello's durable design features software and hardware protections, making it easy to fly with confidence.

  • Auto takeoff/landing: Lift off or land with a single tap
  • Low-battery protection: Alerts go off when your battery gets low
  • Failsafe protection: Land safely, even if you lose connection
  • Vision positioning system: Downward-facing camera facilitates precise hovering

Thanks to the continued development of drone technology, aerial imaging has become a much more viable and potentially lucrative option for wedding photographers and videographers. Modern drones can capture images like never before, whether it’s a breathtaking still from a new and previously unattainable perspective or a cinematic tracking shot of the entire ceremony. With the right drone, the sky literally is the limit. Let’s take a look at how you can work drones and aerial imaging into your next production.

When using a drone to shoot a wedding, there are several factors you’ll need to consider. The first involves the type of camera you’ll be using. Many modern drones feature a built-in camera of some sort, but not all of them are sophisticated enough to warrant professional use. If you’re planning on using the drone’s onboard camera to shoot your wedding, make sure its specs are up to snuff. All the creative framing in the world won’t matter a lick if the camera can’t produce a quality image.

To that end, one brand you might want to consider is DJI. The majority of its prosumer and professional drones feature high-quality cameras that are suitable for wedding photography and videography.

Of course, you don’t have to use a drone with a built-in camera. You can use your own equipment instead. There are plenty of drones available that are designed to carry professional camera equipment, including DSLRs and mirrorless cameras. If you are planning on using your own equipment, just make sure the drone can support it—in terms of interface and weight. All drones have a payload limit, meaning they can only carry a certain size and weight of camera. For heavier cameras, especially DSLRs, you might need a drone with more booms (arms) than your standard quadcopter, which has four. We’re talking a hexacopter or possibly even an octocopter. More booms means bigger payloads, which means it can support heavier cameras. Before you say “I do” to a particular drone, make sure it can bear the weight of your equipment.

Gimbal for Video

Another factor you need to consider is the drone’s gimbal. The gimbal is an essential piece of hardware, especially when it comes to videography. In fact, you could make the argument that it’s just as important as the camera. After all, what good is a top-of-the-line camera if all your footage is shaky and/or out of focus?

In general, the type of drones you’ll be looking at will have either a two- or three-axis gimbal—but most likely the latter. A two-axis design typically can tilt (pitch) and also cant (roll) the camera, the latter adjustment keeping it level relative to the horizon, unless you want a Dutch angle. On top of keeping your shot level and allowing tilt, a three-axis system enables the camera to pan (yaw) as well. On aircraft with retractable landing gear, this can mean a full 360 degrees of unobstructed shooting. Mounting a camera rigidly without a gimbal will render unusable video. Not only will it lead to extremely shaky footage, it will also mean a lot of rolling shutter wobble from most CMOS cameras—that is, just about every camera on the market. Rolling shutter is particularly bad on larger-sensor cameras with slower read-outs, such as DSLRs and mirrorless cameras.

Gimbal for Photo

For photos, one could argue camera stabilization is not required. However, a gimbal is still highly recommended. For one thing, it gives you some degree of camera control independent of the copter, and means the camera can stay locked on a subject to catch just the right moment, even if wind conditions cause the aerial platform to rock and sway. Additionally, as with lens-based optical image stabilization, having a steady camera decreases the minimum shutter speed you can get away with using. In broad daylight, this might not be a big deal unless you are applying ND filters to capture motion blur, but in low light, the ability to use slower shutter speeds can be a major boon.

Monitoring

Whether you are taking stills or recording video, you will need a way to monitor from the ground to compose your shots. Many purpose-made aerial cameras have some form of video transmission built in. Or you can pick up a separate video transmitter and receiver set. Either way, this can be an old-school analog 5.8 GHz system or a digital system that is either 5.8 GHz or, more likely 2.4 GHz. Analog 5.8 GHz systems still have the longest range out there, and can hold up to weak signals better. On the other hand, the quality isn't going to be spectacular.

Modern digital downlinks offer HD image quality and often additional camera/gimbal control via the app or a dedicated radio controller. The trade-off is that range may be reduced under the burden of the added bandwidth. Between 2.4 GHz and 5.8 GHz digital systems, 5.8 GHz has shorter range, but also won’t create interference with 2.4 GHz flight control systems.

In addition to traditional field monitors or using a mobile device's screen where there's an app, increasingly, aerial imagers are turning to so-called FPV goggles. The FPV, or first-person view market, is all about seeing the world from a bird's-eye view. FPV goggles look like futuristic VR headsets, and many even use head tracking to move the camera as you turn your head. But they provide a great way to monitor, especially in bright daylight, where a field monitor might be hard to see. Some goggles have 5.8 GHz receivers built in, and are usually distinguished by mushroom-shaped "cloverleaf" antennas protruding (the actual cloverleaf is inside the mushroom-shaped protective dome). Alternatively, many monitors with built-in receivers have video output. This means a pilot can use the monitor and keep visual contact with the copter and view OSD telemetry data, while the camera operator uses the goggles to concentrate just on framing and camera work.

Remote Control

As mentioned, dedicated aerial cameras typically feature app-based control. In addition, the handheld controller (transmitter) for the aircraft itself can often have controls assigned to operate the gimbal (or a whole separate transmitter can be used). But what if you're using an action camera, DSLR, or mirrorless camera? For video, you might opt to just let the camera roll the whole time; let's face it, on most copters, you'll get 25 minutes of flying time—if you're lucky. Even DSLRs can usually roll for up to 30 minutes in a clip.

If you need camera control, you'll want to consider the gimbal you select. Many that are camera specific—which most currently on the market are—feature a downlink for the shutter release. With these, the gimbal would link to the copter's flight control system. You would then need to program a switch or button on the controller to operate the shutter release.

Many camera-specific gimbals allow you to assign a toggle or switch on the transmitter (pictured here) to operate the camera shutter release.

Other than the shutter, you are pretty limited. The best plan of action might be to leave the camera in Program or your preferred auto-exposure mode. Depending on your aperture setting and camera-to-subject distance, you might get away with locking focus. Otherwise, you'll need to entrust autofocus.

One thing to note: Many cameras have their own built-in wireless functionality—newer GoPro HERO models, for example—and even an increasing number of pro cameras. Do not use this feature. Chances are it operates on 2.4 GHz, the same frequency as most RC aircrafts’ radio-control systems. Normally, Wi-Fi routers and other 2.4 GHz radio devices in the vicinity aren’t a problem; frequency hopping means devices can work around interference. But when you have a 2.4 GHz Wi-Fi transmitter on a camera that is mounted in extremely close proximity to the copter's control receiver, you are asking for trouble. This is part of the reason video downlinks are almost always 5.8 GHz.

Audio for Video

Drones can be noisy. At close range, it is unlikely you will be able to avoid picking up motor and wind noise, regardless of how you mic your subject. For long shots, noise won't be a problem, but the shot will probably be too wide for lip-sync to be noticeable. For wedding shooters, UAVs are best for scene setting, acquiring establishing shots such as the exterior of the church or temple, or for staged scenes where capturing live sound is unnecessary.

Safety Tips

As long as the copter knows where it is in space, based on its GPS position, it can overcome many of the worst pilot mistakes, and many UAVs are equipped with this sort of intelligence. If you choose to fly indoors, you will not have this safety margin. Gyros, accelerometers, and other sensors will still help keep the copter from stalling. But they can't bring the quadcopter back automatically if you lose control of it. A few employ ground-facing cameras to recreate the positional awareness GPS provides. However, even these systems are nowhere near as reliable as having true coordinates from which to work. If you plan to fly indoors, ensure that you are very, very comfortable with your aircraft.

As in other avenues of video and photo production, UAVs have the potential to be great tools. But they are mini aircraft with very sophisticated computer control systems. Using them responsibly requires a great deal of respect for the technology, as well as lots of practice flying. Additionally, legal considerations have to be taken into account.
