Apple Acquires AI Tech That Can See a Photo’s Aethetics

Apple has quietly acquired a new French technology startup, Regaind, which specializes in AI and computer vision for analyzing photos. Apple’s Photos app is already able to search through images using keywords like “dog” or “tree” and pull out the relevant images, but this acquisition may indicate further AI developments for the app.

TechCrunch reports, based on multiple sources, that Apple stealthily acquired the startup earlier in the year.

“Regaind API gives meaning to photos,” the Regaind website states. “We help businesses and developers deal with massive flows of images by using state-of-the-art artificial intelligence to analyze and sort them.”

The technology is able to assess a photo’s “technical and aesthetical values” — things like aesthetics, sharpness, and exposure — rather than just determining the subject matter that’s featured in each image. This is something that will likely benefit lots of iOS features, such as Apple’s Memories which could pull together more meaningful collections.

On the Regaind website, you can see the technology in action. It applies different properties to each image, allowing a system to quickly determine which photos are actually worth highlighting.

Particularly impressive is its ability to properly analyze people in an image, even determining gender, age, and other details.

The “Properties” assigned to photos include things like “Interesting/original subject,” “Subject well framed,” “Annoying background,” “Great composition,” and “Good timing.”

Details of the acquisition are limited, though, and Apple tends to be rather secretive about such things.

“Apple buys smaller technology companies from time to time, and we generally do not discuss our purpose or plans,” the technology giant said in a statement to TechCrunch.

New Japanese Anime to Feature Realistic Canon Cameras

There’s a new anime series coming out in Japan that may have the most accurately depicted cameras of all time. The reason is because Canon was recruited a consultant for ensuring that all the cameras and photography in the show are realistic.

Just Because! is a new original anime series that’s set to debut in Japan on October 5th, 2017. One of the main characters, Ena Komiya, is a high school sophomore who’s an avid member of the school’s photography club.

But the club has fallen upon tough times and is at risk of being disbanded. In order to save the photo club, Komiya plans to enter her photos in a photography competition.

DC Watch reports that Komiya’s main camera will be a $729 PowerShot G5 X high-end compact camera. Other Canon products to make an appearance will include the Canon 7D Mark II (as a popular camera in the photo department), EF 100-400mm f/4.5-5.6L IS II lens, and EOS M6 mirrorless camera.

Canon worked with the show to ensure that the scenes depicting cameras and photography won’t make photography lovers cringe. Instead, you’ll be treated to an extremely high level of realism.

Here’s a short 30-second trailer for the show in which Komiya makes a brief appearance with the 7D:

If you’re based in the US and are interested in watching Just Because!, you’ll be able to watch it through Amazon’s Anime Strike service.

How to Dramatically Shape the Light of a Landscape Photo in Lightroom

Lightroom’s adjustment brushes allow you to apply local adjustments to specific areas in your photos — great for landscape photography. In this 18-minute tutorial from PiXimperfect, learn how to use the brushes to “shape light” in landscapes.

In this example, the photo in question has some blown highlights and lost details in the shadows. But quite a bit can be recovered with some Lightroom editing.

Pressing ‘K’ will open the adjustment brush tool, and you can then paint a mask over the areas in the image you want to adjust. Once you’ve done that, move the sliders (the same ones you’d see for a more global adjustment) to create the edit. Ensuring that your adjustment brush is sufficiently feathered will ensure the changes look natural.

If you want to add warmth and color to an image, such as bolstering the look of a sunset, you can simply locally adjust the white balance. Just select a new brush, pull up the temperature slider, and paint on the orange.

If you adjust the tint for the brush you’ve used to introduce a white balance change, you can make it a little more magenta in color. This introduces some nice, subtle pink/red tones into the shot.

And don’t forget about the “flow” setting for your adjustment brush. It describes the opacity of the adjustment, so if you have a flow value of 10, you’re painting on your change at 10% opacity. You’d have to paint 10 times to get the same effect as 100% opacity (or flow). This is a great way to reduce the intensity of your change.

When you’re done, your changes can look something like this:

The secret is to keep in mind where the light is coming from in the original photo when you’re making the adjustments — that way you can keep things looking natural.

How to Shoot an Annie Leibovitz-style Group Portrait with Affordable Gear

One way portrait photographers like Annie Leibovitz light large-scale group photos is by lighting smaller groups by themselves and then compositing everyone together into a large group. Photographer Barry Harley recently employed this technique with relatively affordable gear for a group photo with friends while on vacation.

Harley, his wife, and a group of friends were on a week-long vacation at Duns Castle in Scotland. The ancient site was the perfect location for an epic magazine-style group photo.

In Harley’s camera bag was an older Canon 5D Mark II DSLR (~$600 used these days), two Yongnuo YN-560 II flashes (which currently cost about $75), a PocketWizard, and a 43-inch Westcott bounce umbrella (~$20).

The group had brought along outfits specifically for the photo shoot, and upon arrival, Harley decided to shoot the portrait on the main entrance stairway of the castle.

After planning out everyone’s positions and fixing his camera on a tripod, Harley first shot some test shots and photos in which he properly lit different portions of the background.

Next, Harley lit and shot different groups of people using the flashes and umbrella mounted to a C-stand — some were small groups and some were large groups lit multiple times in different ways:

Once he had photographed all the group members, Harley began compositing the people onto a background photo he shot of just the stairs.

After some more grading and retouching, voila: the group portraits were done:

You can find more of Harley’s work on his website, Facebook, Instagram, Twitter, and Tumblr.
