![]() The Dolby proposal recognises that higher frame rates should be available to minimise motion blur, as well as so-called “better pixels” which address colour gamut and luminance. Key to these elements, says Dolby, are “nits”. “Nits” are not head-lice but a measurement of light sources and reflection. For example, the sun’s direct light output is measured at 1.6 billion nits, while starlight is expressed as 0.0001 nits. The reflection of light on a car might produce around 300,000 nits, while the reflection of light from green foliage might only be 40 nits. ![]()

![]() The Atmos experience is one you have to try yourself. Although the differences are subtle, they’re certainly there, and given a few years — the timeline Dolby’s looking at — it’s easy to imagine Atmos becoming a staple of movie theatres, and even particularly glitzy home cinemas. Sadly, if you want to give Atmos a go right now, your options are pretty limited — apart from Dolby’s invite-only cinema, the only cinema in the UK with Atmos is the Empire in Leicester Square. |
