Hasselblad Phocus 3.4 update adds new shadow/highlights tool, adjustment layers, more

07 Dec

Hasselblad has released an update to its medium format post-production program Phocus. Focus version 3.4 adds improvements across the board, including improved shadow and highlight tools, new adjustment layer tools, expanded live view options, new lens profile, and more.

The enhanced Shadow Fill and Highlight Recovery tools have been ‘significantly enhanced.’ Hasselblad says the updated algorithm ‘enables photographers to fully utilize the dynamic range available in their images,’ although exactly how it’s changed remains a mystery. In the event the updated methodology isn’t what a user wants, or the a user is working with previously-corrected images, Hasselblad has also included the old algorithm under a selectable version option.

Hasselblad has added Shadow Fill and Clarity options to the adjustment layer tools so they can now be used as local adjustments with the brush tool and linear and radial gradients. A new Detail tool has also been added under the exposure toolset. This new tool is used alongside the Clarity tool to fine-tune the local contrast in an image.

Focus 3.4 also includes a new Live View Aperture option that lets users ‘to automatically open to the widest aperture possible or to use the selected aperture instead when activating live view.’

Also new is an updated Noise Filter tool and additional lens profiles for the following lenses:

• XCD 2,8/65
• XCD 1,9/80
• XCD 2,8/135 with X Converter 1.7

First look: Skylum Luminar 3 adds support for photo libraries, Digital Asset Manager to follow

07 Dec
Skylum Luminar 3’s layout.

Luminar’s library is set to open soon, but expect construction to continue through at least next year.

The long-awaited update to Skylum Software’s photo editor adds in-app photo library management, which the company says is the first step toward building out a complete Digital Asset Manager (DAM). Called ‘Luminar with Libraries’, this version more directly competes with applications that organize your photos, such as Adobe Lightroom Classic CC and Lightroom CC. Luminar 3 arrives December 18, runs on macOS and Windows, and is a free update for owners of Luminar 2018.

This version more directly competes with applications that organize your photos, such as Adobe Lightroom

That’s mixed news for photographers contemplating a switch from Adobe’s applications, especially since Skylum has been teasing a Luminar DAM for well over a year (and just barely hitting their promise to ship it in 2018). Acknowledging the situation, Skylum is making further updates to Luminar free throughout 2019.

Luminar 3 is a free update for current owners of Luminar 2018. Owners of Aurora HDR, Photolemur, and legacy products can upgrade for $ 49 until December 18. New preorders cost $ 59 until that date, and $ 69 thereafter. There’s no subscription pricing model.

Library vs Digital Asset Manager

Here’s what Luminar with Libraries offers:

  • The Library component is integrated into the application, not existing as a separate app. It keeps track of all the images you throw at it in a browsable image gallery. Photos can be imported from cameras or memory cards, or you can point Luminar at existing folders on your hard disk. Unlike apps such as Apple Photos or Lightroom CC, Luminar doesn’t squirrel the images away to its own folder or container. It creates a central catalog file to track file locations and edits, but the originals remain wherever you put them in the first place.
  • In the Library, you can rate photos from zero to five stars, mark them as flagged or rejected, or apply any of five color labels.
  • You can create albums and populate them with photos.
  • A few shortcuts act like smart albums, revealing photos based on their capture dates, import dates, and recently edited dates.
  • In the Info panel, a limited set of EXIF data is shown, such as the camera, lens, focal length, ISO, aperture, shutter speed, and exposure compensation.
  • You can filter the library based on any of those attributes.
Filter images based on the criteria the Library offers.

Luminar with Libraries covers the basics of wrangling files and making them easily available for editing, but a full DAM provides a deeper level of interacting with one’s photos. Not included in this release is the ability to apply keywords or IPTC metadata, any kind of text-based search, a way to expose and take advantage of location data, or synchronization of images between computers or devices. The interface for importing photos relies on traditional Open dialogs instead of a way to preview the shots.

Editing Changes

Luminar 3 is still the same editor as it was before, with a few enhancements. Presets are now ‘Luminar Looks,’ which sounds like just a rebranding attempt, but actually rolls presets, LUTs, and some AI-enhanced operations into one-click actions.

“Luminar Looks” isn’t simply advantageous alliteration, but a merging of presets, LUTs, and some AI processing.

More significantly, the inclusion of the library into Luminar makes it possible to apply edits to one image and sync them among many other similar photos.

Sync edits from one image to several similar shots.

The Windows version includes improvements to Luminar’s color management to get consistent color among displays and devices, plus a host of bug fixes and performance boosts.

What’s Next

Skylum plans to release frequent updates throughout 2019 to add features and expand the library’s features. In its Luminar Roadmap, the company lists targets for the first half of the year that include:

  • Improved handling of Raw + JPEG image pairs (instead of treating each part separately).
  • The ability to create virtual copies of photos.
  • A Smart Search feature for locating shots “using keywords, EXIF information, and file names” (suggesting keyword support will be forthcoming).
  • IPTC core data editing and syncing among images.
  • Features that use AI technology “when editing skin on portraits, architecture, removing objects or simply applying masks on your images.”
  • A Lightroom migration tool.

Although Luminar 3 won’t arrive with a fully-formed DAM, as many photographers were hoping, incorporating the photo library into the application is still a big deal. Melding the library and the editing tools in the same environment streamlines the overall workflow. It allows you to work on a range of images quickly, without the hassle of opening and saving individual images (and deciding where the edited versions live). It’s a big reason why people stick with Lightroom or use alternatives such as Capture One, Alien Skin Exposure, or ON1 Photo Raw.

Xiaomi co-founder teases 48MP smartphone camera

07 Dec

Earlier this year Chinese smartphone maker Xiaomi announced it had established an in-house camera division. Now it seems the initiative is bearing its first fruits.

Xiaomi co-founder and President Lin Bin has teased a smartphone with 48MP camera module on the Chinese social media platform Weibo. The image he posted shows a close-up of a rear camera with a ’48MP camera’ label next to the lens. Bin says he has used the phone for a few weeks and that it will be released in January.

That’s not an awful lot of information, but it means the upcoming Xiaomi phone will feature the highest pixel count ever on a mobile image sensor. Nokia’s 808 PureView juggernaut came with a 41MP sensor and the much more recent Huawei Mate 20 Pro features a 40MP quad Bayer arrangement.

Like the Nokia 808 PureView and Huawei Mate 20 Pro, the unreleased Xiaomi phone is likely to use its pixel count for high-quality digital zooming, pixel-binning for lower noise, and other computational trickery, rather than outputting enormous image files.

The sensor in question could be the Sony IMX586 quad-Bayer model which was announced in July. At 1/2″ it’s large for a mobile sensor, but due to the high pixel-count, individual pixels still only measure 0.8µm. Samsung’s Bright GM1 is another option with very similar specifications.

It’ll be interesting to see if the new Xiaomi will solely rely on the power of the 48MP sensor or add additional sensors, for example for tele, super-wide-angle or black-and-white shooting into the mix. We’ll know more in January.

Peel apart instant film returns in the form of ONE INSTANT

07 Dec

In 2016, Fujifilm announced it would no longer produce its FP-100C peel apart instant film, citing a dwindling lack of demand for the product. The discontinuation effectively ended the peel apart instant film market, but a new Kickstarter campaign aims to change that. Florian “Doc” Kaps, founder of The Impossible Project, has unveiled ONE INSTANT, a new peel apart instant film expected to launch in 2019.

Following Fujifilm’s FP-100C discontinuation, Kaps had pushed to save peel apart film via SuperSense, the company he founded after leaving The Impossible Project in 2013. The effort wasn’t successful at the time, but has ultimately proven fruitful more than two years later with the unveiling of ONE INSTANT.

As Kaps explains in the video above, ONE INSTANT is a re-invention of peel apart technology featuring single-shot instant film packaged in a paper cartridge. More than two years of research and development went into the innovation.

Kaps explains on the Kickstarter campaign:

In spring 2016 Fuji announced termination of the world’s last instant packfilm production line. Since that day – more than 2 years ago! – we have been desperately searching for “impossible” ways to save this iconic film material. Just like we successfully did with the legendary Polaroid film by purchasing the last original factory in 2008 and restarting production the classic way.

We failed! And honestly this was the best thing that could happen.

The single-shot ONE INSTANT Type 100 glossy color ISO 125 film is ‘based on a new, radical concept,’ the team explains. The product is compatible will all classic Type 100 packfilm cameras and is made with original Polaroid P7 material that was acquired by 20×24 Studio.

The team warns that ONE INSTANT “is truly really expensive to produce,” but they have vowed to bring down the cost when possible by optimizing production. The high cost is due to being mostly hand-made; the campaign explains how production takes place, saying:

ONE INSTANT is a tiny, bespoke, dream-come-true MANUFACTORY in Vienna. ONE INSTANT film editions will be produced WITHOUT the need of giant machines, huge factory spaces and large teams. Our all new manufactory will just consist of a small beautiful darkroom for all production steps that need darkness (mainly the insertion of the negative into the lightproof paper cartridge), a beautiful daylight assembly room and of course our beloved all analog printshop for all paper work, cartridge punching, producing all our hand-made packaging and communication materials.

Backers are offered multiple products to make a pledge for on the Kickstarter campaign, including various ONE INSTANT bundles that feature multiple packs, different box colors, and a Starter Kit that includes a mint condition Polaroid COLORPACK 2 camera. Film shipments to backers are expected to start in May 2019.


Disclaimer: Remember to do your research with any crowdfunding project. DPReview does its best to share only the projects that look legitimate and come from reliable creators, but as with any crowdfunded campaign, there’s always the risk of the product or service never coming to fruition.

Insta360 One X update brings HDR video and Google Street View integration

06 Dec

Insta360 has released a software update for its One X 5.7K 360-degree camera. With version software version 1.1.0 the camera is now capable of capturing HDR video — previously HDR recording was only available for still images. The One X HDR mode makes sure highlight and shadow clipping in your 360-degree videos are kept to a minimum and should make for more natural looking footage, without minimal need for post processing.

The second new feature in the update is Google Maps Street View Integration. One X owners can now use their camera to capture 360-degree content for Google Maps Street View and directly upload to Street View via the One X mobile app. The latter automatically converts video files into a series of evenly spaced 360 photo spheres for viewing on the Google platform.

In addition the company has announced that the One X is now available in a bundle that is exclusive to Apple. The bundle includes a number of accessories, including Insta360’s Bullet Time handle that also serves as a tripod, a selfie stick that is rendered invisible by the camera software, two batteries, and a protective pouch.

The Insta360 ONE X Camera Bundle is now available at Apple.com for $ 449.95. You can read our review of the Insta360 One X here.

Review: The Wacom Intuos Pro is a workflow-boosting machine

06 Dec

Wacom Intuos Pro
$ 299.95 | Wacom.com

When it comes to precision photo editing, a tablet may be the tool you never knew you desperately needed. Although the Wacom tablet has long been a favored tool of graphic designers and digital artists, it’s also an excellent piece of editing gear for photographers.

The Wacom Intuos Pros allows you to return to your roots of putting a pen to paper to create an image – a tactile experience that many younger digital artists may be out of touch with. If you’ve spent a number of years editing with a mouse or trackpad there will undoubtedly be a a bit of a learning curve when it comes to using the pen, but with a little bit of practice you will likely find this device speeds up your editing process and make tools like dodging, burning and clone-stamping much more precise.

Key features

  • 338 x 219 x 8mm / 13.2 x 8.5 x 0.3 in
  • 1.54lb / 0.7kg
  • Wacom Pro Pen 2 with 2 programmable buttons
  • 8192 pen pressure levels (up from 2048)
  • 8 Customizable ExpressKeys
  • Built-in Bluetooth connectivity and USB connectivity
  • Pen stand with 10 replacement nibs (tips)
  • Choose between ‘standard’ or ‘felt’ nibs for added friction
  • Mac and Windows compatible

What’s new

The Wacom Intuos Pro tablet is thinner and lighter than its predecessor, so it occupies less real-estate on your desk. Despite this, the active area is larger thanks to a slimmer bezel and he surface plate can be swapped for a variety of different textures depending on your preferences.

The Wacom Intuos Pro is designed to imitate a large piece of paper

The new version utilizes the Wacom Pro Pen 2, which comes with a weight base (shown below), and is slimmer than version 1 – It also features two programmable buttons and 8192 pressure levels (up from 2048). Wireless Bluetooth connectivity is also new to the Wacom Intuos Pro.

Design

The Wacom Intuos Pro is designed to imitate a large piece of paper. The user chooses the orientation of the tablet and how it will map to their computer screen – this makes it a great tool regardless of your computer setup or dominant hand. On one side of the tablet you will find eight customizable express keys and the touch ring. The power switch and the touch functionality switch are located on the side of the tablet near the express keys and the optional USB plugin is on the opposite edge of the tablet.

The Wacom Pro Pen 2’s stand stores additional nubs. The pen itself has two customizable buttons – flip it upside down and you can use it as an eraser. The tablet itself has rubber grip on the bottom to keep it in place, and its slim profile makes it easy to travel with or store away when space is limited.

In use

It had been a number of years since I’d used a tablet for photo editing, and I can confirm that the learning curve was certainly there. But after a bit of practice with the pen and tablet I found the process of retouching scanned negatives in Adobe Photoshop to be more precise, faster and less taxing on my wrist than it would have been if I were using a mouse. Put another way, the difference between retouching with the Wacom pen vs. the mouse is like hand-writing a note with a fine tipped Sharpie vs a paint roller. The eraser is precise as well. I found it to be particularly helpful when creating multi-layer image compositions.

The vast degree of pressure responsiveness in the Pro Pen 2 is something I really appreciated, especially when it came to dodging, burning and light retouching. Press hard and the results are more pronounced, use a lighter touch and everything is more subtle. If you are particularly heavy-handed you can adjust the overall sensitivity of the pen.

The difference between the Wacom pen and a mouse is like hand-writing a note with a fine-tipped Sharpie versus a paint roller

The buttons on the side of the pen make it easy to control the brush size. At first I found myself accidentally pressing them as I edited, but I eventually learned to slightly rotate the pen while I worked to avoid this problem.

Also of note is that I observed no noticeable lag time between tablet and computer screen when it was connected via USB. The Bluetooth connection also seemed quite good, though I did notice a little bit of latency when using the paintbrush tool for extended periods of time.

Of course, Photoshop is not the only application the Intuous Pro is good for; I also used the tablet to work on images in Adobe Lightroom. And while it was useful for cloning and healing, I found it to be a little unwieldy when making adjustments to the slider. Ultimately I think I still prefer utilizing the mouse and the keyboard shortcuts that have been burned into my muscle memory for Lightroom work.

Bottom line

If you’ve never used a tablet and pen setup – or if it’s been a number of years since you’ve picked one up – the Wacom Intuos Pro will take some getting use to. Give it time though, because if you are doing a lot of image retouching, image compositing or light graphic design work, this editing accessory will certainly boost your productivity. And the customizable functions will make it appeal to a large variety of users. In all, we think that this tool can help take your editing workflow and the final image results to the next level.

What we like:

  • Pen delivers precise results
  • Pressure sensitive tip
  • Lightweight and travel friendly
  • Highly customizable
  • Excellent to use with Adobe Photoshop

What we don’t like:

  • Somewhat laggy Bluetooth connectivity; not a huge problem for light retouching jobs, but could become problematic when making large scale image composites that require a lot of painting.

Buying Guide: The best camera bargains of 2018

06 Dec

Last updated: December 4, 2018

If you’re looking for a high-quality camera, you don’t need to spend a ton of cash, nor do you need to buy the latest and greatest new product on the market. If you’re willing to miss out on some features, you can save a lot of cash by picking up a last-generation model or shopping around for deals on refurbished or older, but still current, cameras.

In this buying guide we want to direct your attention to some great-value cameras, which are still available. We’ll start with the least expensive options and go up in price from there.

Street prices listed below are current as of December 4th, 2018.

  • Sony Cyber-shot DSC-RX100 $ 369
  • Nikon D3400 w/18-55 lens $ 399
  • Canon PowerShot G9 X II $ 399
  • Canon EOS M100 w/15-45mm lens $ 399
  • Sony a5100 w/16-50mm lens $ 449
  • Sony a6000 w/16-50mm lens $ 499
  • Panasonic Lumix DMC-ZS100 $ 499
  • Fujifilm X-E3 $ 799
  • Nikon D7200 $ 799
  • Sony a7 II $ 899
  • Nikon D750 $ 1399

Sony Cyber-shot DSC-RX100
$ 449 MSRP, $ 369 street

While not as capable as later models, Sony’s original Cyber-shot RX100 is an inexpensive way to snag a genuinely compact camera with a 1″ sensor. It has a 28-100mm equivalent lens that will do well in low light at the wide end of the lens, but not-so-great at telephoto. You miss out on the faster lenses, electronic viewfinders and improvements in autofocus and JPEG image quality that arrive in the latest models.

The camera fits in a pocket with ease, though the body is slippery and some may find the controls a bit clunky. The RX100 has a 3″ non-touch LCD but lacks a viewfinder. Photo quality is excellent and the same can be said for its Full HD video. It focuses quickly and can shoot continuously at 10 fps. Wi-Fi is built-in for photo sharing.

Nikon D3400 w/18-55mm lens
$ 499 MSRP, $ 399 street

While it’s since been replaced by the D3500, the Nikon D3400 is essentially the same camera but in a slightly different (but still very compact) body. Like other Nikons, the D3400’s 24MP APS-C sensor has excellent resolution and dynamic range. Its autofocus system is dated and it can’t take many photos in a burst, so a sports camera it is not.

What makes the D3400 so appealing is that it’s great for beginners, with its ‘Guide mode’, selecting the correct settings for you based on use case, and tells you which of them were actually changed so you learn. The camera also features Full HD video capture (though AF is essentially unusable) and Bluetooth for easy photo sharing.

Canon PowerShot G9 X Mark II
$ 529 MSRP, $ 399 street

The Canon PowerShot G9 X Mark II is one of the cheapest and smallest compact cameras with 1″ sensor that you can buy. The larger-than-average sensor will produce better-looking images than your typical compact, though the slow-ish lens will reduce that advantage in low light.

The lens has a small 28-84mm equiv. focal range, which isn’t as versatile as most of its peers. Despite that, the G9 X II has a well-designed touch interface, snappy performance, Full HD video capture and the latest wireless features.

Canon EOS M100 w/15-45mm lens
$ 599 MSRP, $ 399 street

The Canon EOS M100 is one of least-expensive mirrorless cameras you’ll find. It’s packed with Canon’s latest features, including its excellent Dual Pixel autofocus system and also has a flip-up touchscreen display. It’s not as good at shooting action as the newer M50 model, which can also capture 4K video.

The M100 features Full HD video capture and Wi-Fi with Bluetooth. While there aren’t many native EF-M lenses available, the M100 is compatible with Canon’s enormous selection of EF and EF-S glass with an optional adapter.

Sony a5100 w/16-50mm lens
$ 549 MSRP, $ 449 street

It’s hard to believe but, five years after its introduction, Sony is still making its a5100 mirrorless camera. The compact Sony a5100 is a good choice for those on a tight budget seeking a point-and-shoot experience, but with interchangeable lenses. It hasn’t seen the improvements in video, autofocus or JPEG color that have arrived in newer Sonys, meaning you don’t get the excellent Eye AF feature.

The a5100 uses a 24MP APS-C-size sensor and has a hybrid AF system that’s still responsive today. There’s a selfie-friendly flip-up touchscreen LCD on the a5100, but no viewfinder. It can capture Full HD video and has Wi-Fi with apps you can download to the camera.

More info | Check prices


Sony a6000 w/16-50mm lens
$ 649 MSRP, $ 499 street

The Sony a6000 is one of the best-selling interchangeable lens cameras of all time, and for good reason. It has excellent image quality, a reliable autofocus system, 11 fps burst shooting and a sharp OLED viewfinder. The a6000 is targeted a bit more toward enthusiasts than the a5100, with dual control dials but (disappointingly) no touchscreen. It pre-dates features such as 4K video and Sony’s excellent Eye AF feature, and improvements in interface and JPEG color.

It captures Full HD video, offers Wi-Fi and can download feature-adding apps into the camera. It’s worth pointing out that Sony’s APS-C lens collection is relatively small and expensive compared to other mirrorless brands.


Panasonic Lumix DMC-ZS100
$ 699 MSRP, $ 499 street

The Panasonic Lumix DMC-ZS100 (TZ100 in some regions) is a compact camera with a 1″ sensor and 25-250mm equiv. lens. It fits easily in your pocket, making it an ideal camera for travel. Its lens has a relatively slow maximum aperture, so it won’t perform terribly well in low light, though it will still out-do compacts with smaller sensors. It doesn’t get the nicer JPEG colors of newer Panasonic models.

The ZS100 has a fixed touchscreen display and a ‘better than nothing’ electronic viewfinder. In addition to taking 4K video, the ZS100 also has genuinely useful features like ‘Post Focus’ and ‘4K Photo’. For those looking for a portable, versatile travel camera, the ZS100 is a bargain.


Fujifilm X-E3
$ 899 MSRP, $ 799 street (body only)

The Fujifilm X-E3 is a rangefinder-style mirrorless camera that produces excellent images straight out of the camera courtesy of its modern 24MP X-Trans APS-C sensor. Its well-built body has direct controls for shutter speed and exposure compensation, and most buttons are customizable.

A high-resolution EVF and touchscreen await users on the rear plate. It also offers Wi-Fi and Bluetooth. The X-E3 captures 4K video but not nearly to the high standard or newer models.While it doesn’t have a built-in flash, with a small external one included in the box. The excellent 18-55mm F2.8-4 lens adds just $ 300 to the cost of the camera and is well worth the money.

Nikon D7200
$ 1099 MSRP, $ 799 street (body only)

The Nikon D7200 is a midrange DSLR with a 24MP APS-C sensor that produces sharp images with excellent dynamic range and solid high ISO performance. It’s reasonably small and light and is sealed against the elements. The D7200 has a large optical viewfinder and a fixed 3.2″ (non-touch) LCD.

Autofocus performance is superb, whether you’re tracking subjects or shooting in low light. While the D7200 can record Full HD video, quality isn’t as good as other midrange cameras and autofocus is effectively unusable. The D7200 has built-in Wi-Fi, but the aging smartphone app is unreliable.

More info | Check prices


Sony a7 II
$ 1399 MSRP, $ 899 street (body only)

The Sony a7 II is a solid full-frame mirrorless camera that currently sells for a remarkably low price. It has built-in 5-axis image stabilization, a 24MP sensor, fast hybrid autofocus system and Full HD video capture. The camera has a relatively rugged, with some weather-sealing, high resolution EVF and tilting (non-touch) LCD. It misses out on the further improvements Sony has made in terms of JPEG color, autofocus and user interface in its latest models.

Photos have great resolution and excellent Raw dynamic range, though the a7 II struggles a bit at high ISOs. Some users might find the buttons and dials to be too small, so it’s worth trying one in person before you buy.

More info | Check prices


Nikon D750
$ 1999 MSRP, $ 1399 street (body only)

Despite being released way back in 2014, the D750 is still one of the most attractive full-frame DSLRs on the market and an incredible bargain as it approaches its fifth year of production. The D750’s 24MP sensor produces beautiful photos with low noise at high ISOs and plenty of dynamic range. Its autofocus system tracks subjects with ease, though the camera’s buffer fills quickly when shooting bursts.

The D750’s body is compact for a full-frame DSLR and it has a giant optical viewfinder, a 3.2″ tilting (non-touch) LCD, built-in flash, dual SD card slots and Wi-Fi. It can shoot good quality Full HD video, though autofocus performance in video and live view is for static subjects only. Battery life, on the other hand, is exceptional.

Hipstamatic harnesses iPhone X TrueDepth data to improve TinType app

06 Dec

Camera app developer Hipstamatic says it has found a way to use the depth data generated by the iPhone X to improve the way its TinType app works out which areas of a picture to render out of focus. The depth information the new camera phone creates has allowed Hipstamatic’s developers to identify a genuine plane of focus instead of having to guess and simulate the effect just with software blurring.

A portrait taken with the new app showing a map that demonstrates the area of the image the camera takes to be the subject and where the plane of sharp focus should be

Hipstamatic founder Ryan Dorshorst says that the TrueDepth feature of the new iPhone X provides information at every pixel about how far away the subject is, so with a subject identified it is a much easier job to determine what is background as well as what is in front of and behind the subject – and to blur only those areas. This allows the developers not so much to improve the impression of a tin type’s characteristics but the extremely shallow depth of field that we associate most with large format cameras.

In previous versions of the app a ring of blur was placed around the subject based on where the camera was focused, but it was only really effective when the subject was a person and they were in the right part of the frame. The new v2.1 version bases the decision about where the blur should go on real depth data, so the effect can be applied in a convincing way in a much wider range of situations.

The app is only available for iPhone users, and can be downloaded from the Apple App Store. For more information on the TinType app see Hipstamatic’s TinType page.

Xiaomi details DeepExposure, an AI that automatically fixes image exposure and detail

06 Dec

Chinese company Xiaomi’s AI Lab has published a new paper detailing an AI network called “DeepExposure” that improves low-quality images through machine learning. “Comparing with other methods,” the researchers explained in their paper, “our algorithm can restore most of the details and styles in original images while enhancing brightness and colors.”

DeepExposure utilizes generative adversarial networks and asynchronous adversarial learning to split low-quality images into segments called sub-images. The system computes both local and global exposures for these sub-images, then evaluates their quality before blending them with the original image.

The end result is an image with improved exposure and detail, opening the door for future solutions that may automatically enhance low-quality photos. It’s possible that Xiaomi may one day offer this technology on its smartphones, which already offer other AI capabilities.

The researchers point out in their paper, “Due to the requirement of expertise of photography, photo quality enhancement is beyond the capability of non-professional users, thus leading to the new trend of automatic techniques of image retouching.”

The study indicates that DeepExposure could also be adjusted in the future to improve image tone and contrast.

Xiaomi isn’t the only company using artificial intelligence to automatically improve images. Earlier this year, researchers with Intel and the University of Illinois Urbana-Champaign detailed a deep neural network able to brighten low-light images without reducing their quality. Similarly, a technology called Deep Image Prior was unveiled last year with the ability to recreate damaged parts of an image based on the image’s existing elements.

Qualcomm’s new Snapdragon 855 chipset offers faster depth sensing, 4K HDR video at 60fps

06 Dec

Qualcomm has announced its new flagship mobile chipset that we should expect to see in most 2019 high-end Android smartphones, including the Samsung Galaxy S10.

From an imaging point of view the most interesting news is an upgraded Spectra image signal processor (ISP) that is taking over some tasks that previously have been performed by CPU, GPU and DSP in conjunction. For example, the ISP can process depth mapping at a frequency of 60 frames per second. This should be useful for real-time object attenuation applications but could also help improve simulated bokeh effects in video footage.

In addition the new ISP enables 4K HDR video capture at 60 fps and Qualcomm also claims the processor generally needs only about 25 percent of the power for the same task than previous variants.

For general computing the new chipset’s 7nm process is expected to deliver improved performance while yielding noticeably better battery life then the current Snapdragon 845. The Snapdragon 855 should also bring performance improvements to AI-applications. Qualcomm says the new chipset delivers “up to three times the AI performance compared to the previous generation mobile platform”.

In terms of connectivity the 855 won’t come with 5G but instead use Qualcomm’s new X24 LTE modem which is capable of theoretical download speeds up of to 2Gbps. However, device manufacturers will have the option to add an X50 5G modem to their packages if they they want to include 5G connectivity in their Snapdragon 855-powered products.
