UAE – Sony used its exhibit at NAB 2015 in Las Vegas, US, to demonstrate its latest High Dynamic Range technologies and workflows which it says opens up new possibilities for creative expression and viewing experiences.
The manufacturer showcased comparisons between High Dynamic Range and Standard Dynamic Range across environments such as in the colour grading room or TV viewing at home.
“As the industry pursues resolutions of 4K and beyond, the impact of dynamic range on the overall image quality is often understated,” said Vivian Saldanha, business head, content creation sales and market development, Sony Professional Solutions MEA. “High Dynamic Range is what will contribute greatly towards more immersive images and superior creative expression, and bring us into the future of content creation and consumption.”
Sony’s High Dynamic Range mastering process consists of a combination of high brightness, high contrast, wide colour gamut, and high resolution that requires video from a top quality camera, together with a master monitor capable of faithfully reproducing High Dynamic Range images.
Sony’s F65 and PMW-F55 CineAlta cameras deliver a colour gamut wider than that of print film, and a wide dynamic range (14 stops) that faithfully captures light and dark areas with minimal white clip and black crush. There is also now a monitor available that can do justice to the capabilities of such cameras – Sony’s new BVM-X300 4K OLED master monitor which was launched earlier this year. It uses a unique wide colour gamut OLED panel and an original colour management system to deliver truly high brightness, high contrast, and a wide colour gamut, all at 4K (4096 × 2160) resolution.
The combination of such technologies make it possible to see just how amazing High Dynamic Range images really are, delivering realistic experiences previously available only to the naked eye: blazing fires, stars in the night sky, sunlight dancing on water and much more.
Sony says High Dynamic Range imaging opens the way to highlights that go beyond the limits of broadcast standards, while significantly expanding the colour gamut. Bright areas that are typically saturated in conventional Standard Dynamic Range now retain their true colours in High Dynamic Range, giving video producers access to a broader creative range and new levels of realism and expressiveness. Furthermore, High Dynamic Range reproduction can also be applied to existing F65 and PMW-F55 raw image assets – affording these images a new lease of life, and adding new value.
