Last year, we wrote a detailed description about the difference between HD (High Definition) and SD (Standard Definition) Television. There is a new format called 4k, which was introduced back in 2005, but just now starting to be embraced.
The industry needed a resolution that would work if the audience were sitting in the optimum “one-and-a-half times the screen height” from the screen or closer, and found it required that resolution to be higher than 1080p. The Digital Cinema Initiatives (DCI) was formed in 2002 with the goal of setting a digital standard. Based on these efforts, two new resolutions came about: a 2K specification, and later in 2005, the 4K format.
The first high-profile 4K cinema release was “Blade Runner: The Final Cut” in 2007, a new cut and print of the 1982 masterpiece. Unfortunately, at that time very few theaters were able to show it in its full resolution. It would take one of director Ridley Scott’s contemporaries to truly drive 4K into your local cineplex.
