Indemnis Nexus parachute for DJI drones is first to achieve crowd safety standard

12 Jan

Indemnis has announced its Nexus parachute system designed for DJI drones is the first to be certified as compliant with the ASTM F3322-18 standard. The system is designed to prevent a faulty DJI drone from free-falling to the ground by deploying a small parachute, which slows the drone’s descent for a safer, more gentle landing.

Both the US and UK require drone operators to get permission before operating a small UAV (sUAV) above a crowd, a limitation that intends to protect innocent bystanders from injury in the event of a drone crash. Waivers are offered on a case-by-case basis by both the US’s FAA and the UK’s CAA, but require operators to show how people below will be protected if the drone experiences a failure mid-flight.

The FAA granted its first waiver in October 2017, when it gave CNN permission to fly a Vantage Robotics Snap drone featuring protective rotor cages over a group of people. A parachute system like the Indemnis Nexus offers a different type of protection, one that is the first ever to meet the international ASTM F3322-18 standard for small UAVs.

The standard covers deployable sUAV parachute systems, including design, fabrication, and testing, and was designed to help drone operators get permission for flying over crowds from agencies like the FAA and CAA.

According to Indemnis, it was required to pass a series of 45 functionality tests spread across five drone failure scenarios. Testing took place at New York’s Griffiss International Airport in a controlled airspace; the Northeast UAS Airspace Integration Research Alliance oversaw the process.

The Indemnis Nexus system is designed to strap onto existing DJI drones, which it monitors using sensors. If the sensors detect a flight disruption, a ballistic launcher deploys a parachute at 90MPH / 144kmh. The tube containing the parachute is designed to inflate in order to protect the parachute from the drone’s rotors and body.

The drone was validated for use with the DJI Inspire 2, but may be offered for the Matrice 200 and 600 series, as well, by the end of the year.

Want your sports photos to stand out from the crowd? Use a strobe

How to get these shots

A post shared by Garrett Ellwood (@gwephoto) on

Garrett Ellwood’s body of work speaks for itself. He’s a seasoned sports photographer and, according to his website, has been the official team photographer for the Charlotte Hornets, Carolina Panthers, Denver Nuggets and Colorado Rapids. Since 1995, he’s photographed 19 NBA Finals. So he’s got some experience.

While Ellwood’s more ‘standard’ action shots are well executed, images like the one above spark a lot of interest and attention because they’re different. Ellwood is still capturing a moment, a play in the game, but the result is evidence of greater pre-visualization and planning. Oh, and triggers, and very powerful strobes.

For those who aren’t sports shooters or who aren’t well-versed in using flash, here’s a quick breakdown of his (likely) setup.

A post shared by Garrett Ellwood (@gwephoto) on

The first thing you’d need for this sort of stuff is permission, and given Ellwood’s experience, he’s sure to have it. Next, you’ll need radio triggers; PocketWizard’s are the industry standard, and cost a pretty penny, but they’re reliable and have great range. You’ll then need to mount your strobe pretty high up in the rafters, and because of the distance from your subjects, it’d better be powerful.

We can also tell from these images that it’s likely a bare bulb (evident in the first image from the very hard shadows, the second image appears to have players more ‘filled in’ from light reflecting off the court). It looks to be in a cone-shaped reflector of some sort, or behind a grid – we can see this from the pronounced falloff midway up the court. Ellwood could have underexposed the background in two ways; first, he could have used a very narrow aperture, or he could have used high-speed sync, or a combination of the two. From there, just pump up the flash power to your desired level, and fire away.

The result is a decidedly different and dramatic look. The moral of the story? You don’t have to keep the strobes relegated to staged portraiture or studio shots – experiment with how your particular setup allows you to balance with ambient lighting scenarios, and have fun!

Crowd pleaser: Sony FE 24-70mm F2.8 GM real world images

11 Mar

Sony’s new FE 24-70mm F2.8 G Master is as pro-level as pro-level lenses come. Dust and moisture-sealed, it offers impressively fast AF speeds due to Direct Drive SSM, especially when paired with the Sony a7R II (which we used to shoot this gallery). Though we only spent about 24 waking hours with it, images shot throughout the focal range show the lens is sharp, even wide open. Note that chromatic aberration was turned on in-camera and is therefore applied even to the Raws. Please note, we’ve included Raw files for download for a selection of the images, and you can look at CA performance in a non-profile aware Raw converter (like RawDigger).

Note: This sample gallery was shot while on a Sony-sponsored shooting event in Miami. Part of the excursion included photographing models in scenes that call back to famous Miami-based TV shows and movies including Scarface, Miami Vice and CSI Miami. No actual gangsters or cops were photographed during the making of this gallery.

5 Tips That Will Make Your Food Photos Stand out from the Crowd

01 Jul

1 Cornish Game Hen

Food photography may be more popular now than ever before. The blogosphere is exploding with pictures of food, and social media sites like Pinterest and Instagram are flooding you with never-ending streams of food photos 24/7. Creating food images that stand out in this massive sea of content is a difficult task. Here are five tips to help you get your food photos noticed.

#1 Don’t be afraid of shadows

Shadows make a scene look realistic, give your food texture, and create mood, so don’t hesitate to make them part of your food photo. To create nice, dark shadows let your light fall onto your food either from the back or the side at a fairly low angle, from just a little bit above the surface of your set. Use reflectors sparingly, or not at all. Reflectors bounce light back into the areas of your photo that your light source doesn’t reach, in other words, into the shadows. So to keep the shadows dark, don’t reflect the light.

1 Salted Caramel Candy

In the salted caramel candy photo above my light was falling onto the set from the back at a low angle and I didn’t use any reflectors.

#2 Imply action

Action makes your viewers feel as if they are part of your scene; that kind of engagement is always a good thing. Action can be literal, such as a hand holding a hamburger or pouring syrup over a stack of pancakes, but there are other (and actually easier) ways for you to suggest that something is happening in your photo. One example is a glass of freshly poured beer. Your viewers likely know that the lifespan of the foam top on a beer is only a minute, so seeing a fresh beer tells them that someone must have just been at the scene to pour it.

#3 Point your lens up at food that is tall and stacked

Shooting up from slightly below the food is an unusual angle for food photography; but it can create really compelling images of tall items such as cakes, and things that are stacked, like burgers or, as in the example below, shards of toffee. The food will be towering above the viewer which makes it look big and impressive. Needless to say this angle doesn’t work for flat food, so don’t shoot a pizza with this method.

#4 Create visual contrast

Contrast comes in many varieties and helps make your food photo look interesting. You can create contrast by incorporating different shapes into your photo, such as round and rectangular (or square). You can also create contrast by including colors in your photo that are on opposite sides of the color wheel (complementary), like red and green, or blue and orange. The lettuce cup photo below illustrates both of these concepts, the square dish contrasts the round lettuce cups and the red sauce provides contrast to the green lettuce.

#5 Leave negative space in the image

Don’t feel that you have to fill every square inch of the frame with food or props. A little negative (empty) space gives the food room to breathe, and will keep your viewers from getting overwhelmed and feeling claustrophobic. There are no hard and fast rules that dictate where to leave negative space in a food photo but the rule of thirds is always a good place to start. Imagine your photo dissected into thirds, both vertically and horizontally, and place your subject on or near one of the four points where those lines intersect. Leave the rest of your photo empty and take a test shot. Does the scene look good to you or is it too barren? If it looks like it’s missing something, add more elements to the frame, one by one and along the imaginary lines that dissect your frame, until you have a composition that looks pleasing to you. That’s how I went about composing the Thai curry ingredients shot below.
