In the real world, light levels vary enormously. Our current screens can't reproduce images that include light sources or reflections of them accurately. To do so would require a massive increase in brightness. But it needs to be done. Phil Rhodes explains the science needed for this next artistic leap
That's a big claim to make, but it's true. This development means that TVs will be able to show videos that handle light in the same way as real-life. In our view, it's much more important than merely having more pixels, and the good news is that it's compatible with some existing cameras!
Even with an abundance of incredible views, you still need an outstanding eye for composition and a highly developed photographic technique to get pictures like these
RedShark Technical Editor Phil Rhodes lifts the veil on Dolby Vision, a revolutionary high dynamic range display system that could change how films are made and shown.
Just because we can do 16 bit, High Dynamic Range, 6K and 8K: does that mean we need it? Here's where to start in the debate
Just in case anyone was in doubt that the 4K revolution is happening, Nvidia has just announced that its much anticipated Tegra 4 mobile chipset will include "4K Ultra-High-Def video support"
We're very excited about this video. It is filmed using HDR (High Dynamic Range) and gives the video a very distinctive look that is entirely appropriate for its subject matter: New York. And it may just be a very important moment in the history of film-making
Phil Rhodes wonders what happens now that the best digital camera costs less than the best film camera ever did.
HDR imaging has been one of the sleeper stories of technological advancement over the past couple of years, but with the International Telecoms Union (ITU) looking to fold it into a future Ultra HD spec and the chance of some major film franchises — think Star Wars and The Hobbit — mastering in it, it’s time may finally have come.
