    Google Research explains the Pixel 2 portrait mode

    Background-blurring portrait or bokeh modes have pretty much become a standard feature on dual-camera equipped phones. Similar effects can be achieved with single-lens devices but operation tends to be more cumbersome, with more manual interference required, and results less realistic than on dual-camera setups.

    On the the new Pixel 2 models Google has been able to implement a portrait mode on a single-lens phone that can compete with the dual-camera competition in terms of both operation and image results.

    Marc Levoy and Yael Pritch, two of the engineers behind the Pixel 2 portrait mode have now explained in a comprehensive post on the Google Research Blog how this has been achieved.

    The Google Pixel 2 offers portrait mode on both its rear-facing and front-facing cameras and uses machine learning and neural networking to generate a foreground-background segmentation. On the rear camera the initial segmentation-based depth-map is further improved using depth information generated by the Pixel 2 image sensor’s dual-pixels and a stereo algorithm.

    In a final step the information from both depth maps is combined to calculate the amount of blur applied to each part of the image and generate the end result. If you are interested in a more detailed description of the process you can find it, along with a range of sample images and illustrations, on the Google Research Blog.

    Google’s Visual Core might soon give Pixel 2 HDR+ processing a boost

    Google’s Pixel 2 launch event on October 4th put a lot of emphasis on the new smartphone’s camera capabilities. However, the presenters at the event left out one very interesting detail: Google Visual Core.

    Visual Core is a system-on-a-chip, designed to power and accelerate the Pixel 2 phones’ much-lauded HDR+ function that achieves better dynamic range and reduced noise levels through computational imaging.

    The new Pixel 2 phones already come with the chip built in but it has not been activated yet. It appears Google ran out of time before the Pixel 2 launch to fully optimize Visual Core implementation in the device.

    The good news is it will be activated at some point “over the coming months” which should make HDR+ processing on the new devices even quicker and smoother than it already is. According to Google it will then be 5x faster and use less than 1/10th of the the energy”, a real advantage over the current general purpose processing. In the future the chip could also take over additional image processing tasks.

    The company will also enable Pixel Visual Core as a developer option in its Oreo 8.1 preview, allowing access to HDR+ for the developers of third-party camera apps. All of this is currently of course limited to Google’s Pixel 2 devices but there’s hope other manufacturer will pick up the Visual Core technology and associated software in the future.

    HDR is enabled by default on the iPhone 8 Plus, and that’s a really good thing

    Capturing HDR (high dynamic range) photos using an iPhone or iPad camera isn’t a new feature, but using it in the iPhone 8 Plus is the first time I’ve been wowed by it.

    HDR images are balanced and realistic, to the point where you may not even think about whether a photo is HDR or not. In fact, in the iPhone 8 and iPhone 8 Plus, Apple is so confident in the results that HDR is an automatic setting. When I mentioned to a friend that I was testing the HDR feature, he visibly winced, but there’s no need: Apple’s implementation shows that the term “HDR” doesn’t have to be associated with the garish, hyperreal look of a lot of HDR imagery. They’re often just darn good photos.

    HDR Auto by default

    On iPhone 7, iPhone 7 Plus, and earlier models, even under iOS 11, the HDR mode can be manually turned on, off, or set to Auto in the capture interface. On those devices, Auto means the camera decides whether HDR should kick in to improve a photo when capturing scenes under low light or with a lot of tonal contrast (such as a bright sky and dark foreground). A small yellow “HDR” icon appears at the top of the screen when it’s active.

    Capturing the HDR photo saves two images: the original metered image and a single HDR version that is a blend of three exposures (regular, light, and dark, which are recorded and combined in-camera, not saved as individual images). You can opt to hold onto that original by going to Settings > Camera > HDR (High Dynamic Range) and choosing Keep Normal Photo.

    For the iPhone 8 and iPhone 8 Plus (and the forthcoming iPhone X), however, auto HDR is enabled by default. And → continue…

    Atomos Free Firmware Update – Making Capturing HDR and HLG Easier Than Ever

    By Adam Plowden

    In the latest free AtomOS 8.4 firmware update, Atomos unleashes the power of capturing High Dynamic Range and Hybrid Log Gamma.

    For Atomos Shogun Inferno and Ninja Inferno users, the latest free update will allow Hybrid Log Gamma and HDR video to be recorded directly from cameras such as the Sony FS5 and Panasonic GH5. This footage (recorded in Apple ProRes or Avid DNxHR) has embedded metadata that allows for a complete end-to-end workflow, whether that is through editing on standard editing applications or directly uploaded to YouTube for example.

    Previewing in HDR is triggered by the metadata, which automatically adjusts the gamut and gamma of the monitor-recorders display, so you can take advantage of the rich colours and dynamic range of your input source. If you’re shooting with a camera that has a Log output, it is now possible to convert this for previewing a HDR image on the monitor too.

    It is also now possible to record 240fps in 2K on the Panasonic Varicam LT through the cameras RAW output, as well as 4K 12-bit RAW in CDNC up to 30p, and 2K 10-bit RAW at 100/120fps in CDNG also.

    You can check out our recent interview with Atomos at IBC here, and head over here to download the new free AtomOS 8.4 firmware.

    Will you be updating the firmware to make the most of HDR and HLG previewing and recording? Let us know in the comments.

      Google Pixel 2 earns highest ever DxOMark score of 98, bests Apple

      It’s been a couple weeks of amazing camera phone tests over at DxOMark. First the iPhone 8 Plus beat all former phones with a score of 94. Then the Samsung Galaxy Note 8 came in and earned the same overall score, beating the iPhone 8 Plus in the Photo category but falling short in Video. And now… now we have a new proper king.

      After testing the brand new Google Pixel 2, DxOMark has awarded the flagship phone its highest ever marks for a smartphone camera with an overall score of 98.

      As usual, you can read the full review over on DxOMark’s website, where they pit the Pixel 2 against its main rivals in a few head-to-head challenges, but the overall score results can be seen below:

      In the Photo category, the Samsung Galaxy Note 8 is still the best phone out there, besting the Google Pixel 2’s score of 99 by a single point. But when it comes to video, the Pixel 2 is totally and completely unmatched. Its Video score of 96 makes Samsung’s paltry 84 seem a bit weak, and even Apple’s respectable 89 is nowhere close.

      Ahead of doing our own tests with these phones, we’ve been looking closely at the results in the DxOMark tests, and we are very intrigued to say the least. Some of the numbers themselves are rather subjective, and we don’t entirely agree with DxO’s assessment in every category.

      For example, in their outdoor bokeh comparison, the Pixel 2 fares the worst. And the sometimes overly tonemapped (flat) images HDR+ renders may or may not suit your taste: the Pixel 2 vs. HTC U11 high contrast scene demonstration shows the Pixel 2 preserving more overall detail → continue…

        EDIUS 9 – A Complete HDR Workflow in a Simple Package

        By Fabian Chaundy

        Edius 9

        Grass Valley EDIUS 9 is the latest version of an NLE that’s popular with broadcasters worldwide (Windows only). It brings a complete end-to-end HDR workflow.

        For the uninitiated, EDIUS is an editing software that emerged after Grass Valley, the company behind Edius, decided to move up from creating Premiere Pro plugins to making their very own NLE. Now, 12 years on, the developers have announced EDIUS 9 at IBC 2017.

        Though you may not have heard of it, EDIUS is used widely in the broadcasting world, reaching an impressive 90% of broadcasters in Japan. This is very likely due to its import and export support for a wide variety of video formats, which makes it easy for stations to convert footage from various sources such as phones or drones into one unified format.

        Additionally, EDIUS is based around a very simple design, making it possible for users who aren’t professional editors – such as journalists or station employees doing basic video work – to get up and running fast without the need for long training sessions. Also, EDIUS is completely software based without needing any proprietary hardware and relies mostly on the CPU, which allows for basic editing even if you don’t have a powerful video card.

        EDIUS 9 announced at IBC 2017 features support for a complete HDR workflow, ranging from import to a BT-2020-compatible timeline, through colour correction, all the way to export to broadcast or web standards such as YouTube HDR.

        Additionally, EDIUS 9 also brings support for more camera formats, such as the Canon C200 Cinema RAW Light format, and more native support for formats aimed more towards professional cinema rather than broadcast.

        EDIUS follows a buy-once, use-forever licensing approach, without the need for a subscription. There are multi-user licenses available on request, but the basic EDIUS Pro will set → continue…
