High Frame Rate cinema
A while back Simon Reidy, commenting on another post, wondered about my views on 48fps cinema. This has arisen because Peter Jackson previewed some of his forthcoming movie, The Hobbit, which is shot at 48fps, to a group of industry … Continue reading

3D display brightness
Reader Ryan has pointed me at a slightly old (in 3D talk, August 2011 is old) discussion of Active vs Passive 3D technology in Audioholics. Many of the points it makes are well founded, but it also demonstrates a misunderstanding … Continue reading
