High Dynamic Range in Cinema

5 min read

In the captivating world of storytelling, cinema is everything. It can transform a simple story into a visual feast, making every scene unforgettable. The journey to create the most immersive and visually stunning experiences for moviegoers has been marked by constant innovation in cinema. From the transition from 2K to 4K resolution, which brought sharper and more detailed images, to the advent of energy-efficient cinema laser projection enhancing brightness, colour, and contrast, each step has aimed to improve the power of the story. The market introduction of HDR by Barco last year has catalysed a conversation with moviegoers, creatives, and exhibitors alike. As we talk more and more about High Dynamic Range (HDR) and what it means for cinema, we've answered some of the most asked questions to help you understand the impact for theatrical presentations.

Dynamic Range?
Dynamic range refers to the contrast between the darkest and brightest parts of an image. It determines how well a projector can display deep blacks and bright whites simultaneously.

SDR vs. HDR
When we go to the movies, we seek an experience we can't recreate at home. The main goal is always the same; immersion in the story. Over time new cinema technologies have emerged with exactly that goal in mind.

Standard Dynamic Range (SDR) has been the norm for years. Although we have seen some tremendous improvements in cinema image quality, for instance with the switch from lamp-based projectors to energy-efficient cinema laser projection, the dynamic range remained the same, mostly due to the trade-off between power consumption which contributes significantly to the operational cost of a movie theatre. 

High Dynamic Range (HDR) refers to a video standard that has been developed to create images that better match how we perceive the real world around us. For a creative, this opens up the possibility to work with a much wider range of colors, more shades of dark and brighter light. The resulting image shows more contrast and far more detail in both the darkest and brightest parts of the picture. For the moviegoer, this means more life-like images and therefore more immersion. 

"The Door" is a short film made specifically for cinema - and premiered at CineEurope 2025 - showing moviegoers what it means to experience HDR by Barco on the big screen.

To achieve full HDR representation on the big screen you need a technology which can show those very bright highlights and deep blacks simultaneously. The HDR image has a simultaneous contrast ratio which is at least 30 times higher than what we are familiar with in SDR (2,000:1 in SDR vs 60,000:1 in HDR). Some existing technologies like global laser dimming (sometimes referred to as Variable Dynamic Range or DynaBlack) don't increase that simultaneous contrast and therefore are not suited for full HDR representation. While global dimming allows the projector to display brighter or darker elements, it cannot do so simultaneously and results in lifting or dropping the brightness of the entire image with it.  On top of that, they require 6 times more laser power to achieve the currently DCI specified 300 NIT peak luminance for HDR.

HDR by Barco
HDR by Barco employs patented Lightsteering technology to artfully direct light where it is needed to unlock the full creative potential of every scene as imagined by the world's greatest directors and colourists. This smart light distribution allows the moviegoer to experience darker darks and brighter brights. The Barco HDR Lightsteering technology also enables the widest colour gamut: Rec. 2020 (which is 140% of today's DCI-P3 standard cinema colour gamut) resulting in an extraordinary life-like visual experience.

SDR: Still Exceptional Quality
It's important to note that SDR still offers exceptional quality. Especially Laser projection in SDR delivers stunning images with rich colors and sharp details, ensuring an excellent viewing experience while also enabling a broad range of operational and financial benefits for exhibitors.

Conclusion
In conclusion, while laser-powered SDR projection continues to provide high-quality visuals, HDR represents the future of cinema. High Dynamic Range - as defined by the Digital Cinema Initiative - is the next step in delivering even more captivating and immersive experiences for audiences, allowing for lifelike images, representing the true intent of the director. Only HDR offers the ability to reflect the sharpest details in the darkest and brightest parts of the image, alongside the widest colour spectrum, delivering the most immersive visual experience.
