More resolution, High Dynamic Range (HDR), higher frame rates… How exactly do the limits of the human visual system impact our technology?

When is enough, enough? This is one of the most interesting questions brought to mind after a discussion that came up at the recent ARRI Broadcast Day held at Die Fernsehwerft studio facilities in the new creative district of East Berlin Harbour. In a studio filled with international guests from across the industry, Marc Shipman-Mueller – ARRI’s head of camera systems – opened up this topic in a way that has permanently realigned the way I view today’s core developments in digital cinema acquisition, post and delivery.

These are purely my opinions based on an evolving thought process rooted in an exploration of new technology, and not an absolute truth. I may well end up being wrong, and am happy to learn things that may change my views expressed here. In fact, I’d love to open this up to you, and hear some of your thoughts, so I encourage you to leave comments.

Lightroom Mobile HDR Camera Better than iPhone 7 HDR

 HDR Images, HDR Info, HDR Software  Comments Off on Lightroom Mobile HDR Camera Better than iPhone 7 HDR
Apr 152017
 

Adobe just launched an update to Lightroom Mobile that lets users shoot HDR photos on iPhone and Android using the Lightroom Mobile app. The great photo organizing and editing app from Adobe will let users shoot their shots and then edit them after taking the photos. We’ll show users how to use the app to take beautiful shots in difficult lighting situations.

Why Shoot HDR Photos on iPhone?

First, what is HDR? It stands for High Dynamic Range and refers to a special kind of photography where the photographer shoots three or more photos using different light settings for each shot. For example, the person will shoot the first shot to get the brightest parts of the scenery well-lit, but this leaves the mid-tones and dark areas too dark. So they take another shot of the same scenery so that the mid-tones get the best exposure. However, this leaves the brightest areas, like a window in a room or the sky in a landscape photo, too bright. The darkest areas, like the shaded area under a tree in a landscape, look too dark. The third shot gets the best exposure for those dark areas, leaving the mid-tones and bright areas too bright.

An example of a beautiful landscape photo (source Pixabay user: hannsbenn).

Professional or high-end consumer cameras often give photographers the best option for shooting HDR photos. They automatically will shoot three or more shots using different exposure settings. Some apps will mimic this HDR look, but they don’t really work as well. The HDR setting on the iPhone 7 camera works okay, but not as well as Lightroom Mobile. Until now, using the camera app’s HDR setting gave users the best option for shooting HDR Photos on iPhone, but not anymore.

Before Adobe’s update to Adobe Lightroom Mobile, shooting HDR Photos on iPhone meant taking three shots and then exporting them to a computer. The photographer then combines the three or more shots into one shot with excellent lighting for all three areas, light, dark and mid-tones. That means uploading the photos, going to your desktop or laptop computer and opening a photo editor, like MacPhun’s Aurora HDR 2017 editing software or Adobe Photoshop CS.

 

How to Shoot HDR Photos on iPhone with Lightroom Mobile

First, install the app and sign up for an Adobe account if you don’t already have one. To get the most out of the app, you will need a subscription. The Adobe Creative Cloud Photography plan only costs $9.99/month and includes access to the full desktop/laptop versions of Photoshop and Lightroom plus the ability to sync between mobile devices and desktop/laptop computers. The free version lets users take photos using the steps below.

Apr 152017
 

The new 34-foot HDR LED cinema display from Samsung aims to offer impressive performance for a new age of the cinema viewing experience.

Samsung’s latest unveiling in cinema technology has clearly been designed for the new age of viewing experience. The 34-foot LED screen design follows the latest trend of High Dynamic Range, a hot topic that many manufacturers have been chasing after in recent times (check out THIS article for a recent example). Its 146fL (foot-Lamberts) make it over 10 times brighter than regular movie projectors, while offering “ultra-contrast and low tone grayscale settings” for contrast ratio of almost infinity:1.

Of course, it also features Cinema 4K resolution of 4,096 x 2,160, one of the features which make it DCI-compliant.

Canon Working on Global Shutter With High Dynamic Range, by Alex Cooke

 HDR Info, News  Comments Off on Canon Working on Global Shutter With High Dynamic Range, by Alex Cooke
Apr 132017
 

Canon has developed a 2/3″ sensor with a global shutter and high dynamic range, helping to pave the way toward future generations of video cameras.

The rolling shutter is a common issue in video. Because most cameras read each frame of sensor data by scanning across the frame either vertically or horizontally, this means that data from the sensor is not read simultaneously, which can cause artifacts, particularly with quickly moving subjects, the most common example being airplane propellers.

While certain cameras such as the Sony F55 have a global shutter, which reads all sensor data at the same time, the majority still use rolling shutters. Canon’s global shutter CMOS sensor initially had a smaller dynamic range that required two improvements to regain a wider range.

Lightroom Mobile Adds Powerful RAW HDR Capture Mode in Latest Update

 HDR Images, HDR Info  Comments Off on Lightroom Mobile Adds Powerful RAW HDR Capture Mode in Latest Update
Mar 142017
 

Adobe released a major update for Lightroom Mobile on both iOS and Android today. And in addition to a few simple features like “speed review” and a notification widget for iOS, and radial & linear selection tools for Android, Adobe dropped a bombshell: RAW HDR capture… on your smartphone.

Smartphone cameras are improving by leaps and bounds, but they still fall far short of bigger-sensor brethren, particularly where dynamic range is concerned. This update, claims Adobe, will change all that, allowing your measly smartphone to capture a wider range of tones than previously possible:

“The new HDR mode works by automatically scanning the scene to determine the correct exposure range and then capturing three DNG files which are then automatically aligned, merged, deghosted, and tonemapped in the app,” explains Adobe. “You get a 32­bit floating point DNG, with all of the benefits of both an HDR and a raw photo, which is processed by the same algorithms with the same quality as the HDR technology built into Adobe Camera Raw and Lightroom.”

The new RAW HDR mode in Lightroom Mobile should make a mockery of your phone’s built-in HDR capabilities, which can typically balance out only the harshest of tones by using two JPEGs. In comparison, Lightroom’s Mobile’s three RAW DNGs are orders of magnitude more useful.

To take advantage, you’ll have to have an iPhone 6s or newer, iPhone SE, or iPad Pro 9.7-inch on the iOS side, or a Samsung S7, S7 Edge, Google Pixel, or Pixel XL for Android. Additional Android devices are being developed for “as quickly as possible.”

Here are some sample photos, all of them captured using this new HDR mode:

Google adds High Dynamic Range (HDR) video support to YouTube

 Technique  Comments Off on Google adds High Dynamic Range (HDR) video support to YouTube
Nov 162016
 

For some millennials, YouTube stars are more important than popular pop musicians or famous Hollywood actors. Older folks may not understand this phenomenon, but it actually makes a lot of sense — YouTube is a platform where many young people spend their time.

Today, Google announces that it is making YouTube even better. The service can already stream video in 4K, and is available on countless devices, but now the videos are gaining High Dynamic Range (HDR) support too. This means the content will be presented with better contrast and more vibrant colors. Of course, the benefits will only be relaized with displays that support HDR.

“Starting today, you can watch YouTube videos in HDR on supported devices, such as HDR TVs with the new Chromecast Ultra, and soon on all 2016 Samsung SUHD and UHD TVs. If you’re using a device that doesn’t yet support HDR, don’t worry, videos will still play in standard dynamic range. As more HDR devices become available, YouTube will work with partners to enable streaming of the HDR version”, says Steven Robertson, Software Engineer, Google.

Robertson also shares, “any creator can upload HDR videos to YouTube. To make sure creators can tell awesome stories with even more color, we’ve been working with companies across the industry. We’ve worked with the DaVinci Resolve team to make uploading HDR just as simple as SDR videos to YouTube. We’ve also outfitted the YouTube Spaces in LA and NYC with all the gear needed to produce great HDR content”.

Google shares the above side-by-side images to show the potential benefits. As you can see, the HDR image on the right is more detailed and vibrant, while the simulated SDR image on the left looks washed-out.

Want to check out some HDR content now? Google shares the following YouTube playlist that contains videos that are already compatible.

High Dynamic Range. Heard of it? Canon recently released a white paper on HDR written by Canon Fellow Larry Thorpe, laying down the key concepts and preoccupations regarding this emerging technology.

HDR. You’ve probably seen it advertised all over the place: on the latest generation Atomos recorders, on silly smartphone apps that take the High Dynamic Range look way over to the extreme, on new televisions and monitors claiming to be HDR Ready… It seems like its something we should want… but what is it?

In his recent white paper about HDR, Senior Canon Fellow Larry Thorpe explains the trends in advancements in imaging technologies, and the main 5 parameters in which there has been particular preoccupation.

How HDR works

 HDR Images, Technique  Comments Off on How HDR works
Sep 302016
 

High Dynamic Range TVs and devices are here, along with HDR TV shows and movies. You can buy a new 4K HDR TV for as little as $450 and stream HDR Netflix and Amazon, or add a $300 Xbox and spin HDR 4K Blu-ray discs. HDR games are coming soon, and even phones and PC screens are attaching those three buzzy letters.

But how do they work? Is HDR just another marketing gimmick to sell TVs and other gear, with no technology behind it? What does it claim to do, and why is that better?

Well folks, if those are your questions, you’ve come to the right place.

What’s HDR?

For the basics about what HDR is, check out What is HDR for TVs, and why should you care?. The short version is an HDR TV, when showing special HDR content, has a wider dynamic range (i.e. contrast ratio), along with more steps in brightness (for smother transitions and more detail in bright and shadowy areas). Also, usually, HDR is paired with Wide Color Gamut (WCG), which offers a greater range and depth of color.

Unlike 4K resolution, curved screens or 3D, HDR is a TV-related technology we’re actually excited about. In the best cases it actually improve the image beyond what you’re used to with non-HDR video (standard dynamic range, or SDR), including conventional high-def, Blu-ray or even 4K. How much of an improvement–if any–depends first and foremost on the capabilities of TV itself, but also on the content.

Of course you’ll need to be watching actual HDR content on a new HDR TV to see the benefits. Fake HDR “upconversion” is available on some products, but it’s not the same.

Amazon Video now streaming Dolby Vision HDR and HDR 10

 HDR Digital Cinema  Comments Off on Amazon Video now streaming Dolby Vision HDR and HDR 10
Jul 032016
 

Amazon announced on Monday that it is now offering its HDR content in two different standards, Dolby Vision HDR and HDR 10. Prior to today, Amazon had only offered customers HDR 10 content, and the addition of Dolby Vision HDR means that more customers will be able to take advantage of the service on boxes and TVs that otherwise didn’t support HDR 10. As a reminder, Sony, Samsung and LG have used HDR 10 while LG has also chosen to use Dolby Vision HDR on some of its other TVs.

The selection isn’t as large just yet, but there’s some compelling content available including Pineapple ExpressElysium, Fury, Hancock, After Earth, The Amazing Spiderman 2 and Amazon’s original series Bosch. The movies are available for purchase or rent, while Bosch is available for free to Prime members who want to get a taste of what Dolby Vision HDR offers.

The Newsshooter guide to the what, why and how of HDR

 Cinematography, Gear, HDR Digital Cinema, HDR Images, Technique  Comments Off on The Newsshooter guide to the what, why and how of HDR
Mar 312016
 

With the announcement of the Shogun Flame and Ninja Flame today, I thought now was a good time to explain what HDR is and why Atomos have made a panel that can resolve the brightness detail and colour accuracy of 10-bit HDR images.

Atomos have definitely been looking ahead to the future when it comes to HDR. While HDR is still very much in its infancy, Atomos have looked to future proof (as much as you can) their Flame series of monitor/recorders. By adding HDR support now, Atomos are giving you a monitor that will still be relevant for many years to come.

So why do we need HDR and what is it? Grab a coffee because this isn’t something that can be explained in a few paragraphs.

the_hollywood_sign_h_2015

With interest in adding high dynamic range (HDR) to feature and TV content running high, global standards body Society of Motion Picture and Television Engineers opened its annual Technical Conference & Exhibition on Monday with the release of a 50-page HDR study group report that it hopes will help standards bodies and stakeholders to find some commonality and sidestep a potential format war.

High dynamic range is a term used to describe a wider range between the whitest whites and blackest blacks in an image, and is viewed by many in Hollywood’s technical community as a feature that will create a more noticeable different to consumers, compared with resolution (Ultra HD or 4K) or high frame rates.

But with numerous companies and organizations using the term HDR in different ways, there’s concern that this could confuse consumers and possibly even start a format war.

The SMPTE report includes definitions, guidelines and other information. Importantly, it raises “red flags” by identifying key areas that require consensus, including brightness levels, compression and distribution, said SMPTE standards director Howard Lukk.

HDR_TV_Shipment_Forecast

The market for high dynamic range (HDR) TV sets are forecast to become an everyday form factor in the television industry by 2019 when shipments rise to 32.6 million, according to a new report from IHS.

HDR TVs offer enhanced brightness for a broader palette of light outputs and sparking highlights. Currently, HDR TVs are a niche market because of the high price and lack of content for the high resolution displays with only 2.9 million units forecast to be sold in 2016. However, in the next three years, HDR TVs will rise by more than 11-fold, IHS says.

MIT scientists have designed a new camera that will never overexpose a photograph, no matter what the lighting situation is. Called a “modulo camera,” it captures a high dynamic range photo with every exposure.

Instead of capturing multiple photos at different exposures, as with traditional HDR imaging, the camera only requires a single exposure.

As data, images and particularly video keep increasing the data load they consume, the difficulty in transporting them only grows, and this is where HDMI 2.0 and HDMI 2.0a come into the picture. In particular, they’re part of the future of 4K video content.

The video production industry, consumers with their TVs and PC monitors, gamers with their 4K-capable games and almost everyone in between keep piling on the demand for more pixels, more frames per second, more dynamic range, more colors and more whatever will make digital video look so much cooler. Meanwhile all this extra data has to get transported somehow and not just from A to B but from A to B at the speeds and smoothness we’ve all become accustomed to.

This is where HDMI 2.0 and its cousin 2.0a come into the picture. As our daily content loads become ever more difficult to squeeze through the same piping we’ve been using for some years smoothly, the two new versions of the ubiquitous HDMI have become vitally necessary.

Dolby Cinema-970-80

We’ve just checked out Dolby’s newest high-tech cinema in Hilversum, Holland. It’s only the second in Europe and the first to launch with the brand new twin Christie laser projectors necessary for Dolby Vision.

And the most impressive thing about it all was an empty screen.

That might sound utterly dismissive, but it’s genuinely not. The Vision demo I was treated to was seriously one of the most impressive things I’ve seen on a technological level in a cinema. It’s all about those advanced Dolby Vision projectors rocking the latest laser tech mixing wider colour gamut and high dynamic range (HDR).

These new projectors can create contrast levels far in excess of the current generation of digital projectors.

Where even the most advanced projectors are hitting contrast ratios of around 8000:1, and most standard ones around 2000:1, the Dolby Vision beamers are batting above 1,000,000:1. Count those zeros…

And that means real, deep, inky blacks.

If you’ve shopped TVs recently, you’ve no doubt been seduced by the term 4K UHD (Ultra High Definition). When UHD was first introduced a few years ago, it represented a jump in resolution – basically four times the resolution of 1080p HD. That seemed like a pretty big deal, but we now know that, in 2015, UHD is taking on an entirely new meaning. Going forward, the very best UHD TVs will not only offer higher resolution, but also offer more colors than ever before and something called High Dynamic Range, or HDR.

The idea behind HDR is that it can provide a higher level of contrast between light and dark images on the screen to create a much more realistic image. That may not sound like a lot on paper, but in reality, it’s a pretty significant move. In fact, many in the industry believe HDR represents a significantly bigger leap in picture quality than UHD’s higher resolution.

Imagine a TV picture that is more like what you see in real life. One with spectral highlights closer to what you see when the sun gleams off the surface of a lake, or when the stars and moon are especially bright in the sky. Imagine getting to see the exact same shade of green you see on Los Angeles’ highway signs on a TV for the very first time (did you know TVs haven’t been able to faithfully produce that color?) or a shade of red envisioned by a movie director that is so bright and exotic, you’re convinced you’ve never seen it before. HDR makes that possible.
