There's another confusing video acronym on the horizon: HDR, or high dynamic range. When it comes to photos, HDR refers to merging footage shot in different exposures into a single, hyper-realistic scene -- for video it's more about improving overall contrast. Today Amazon announced that it'll be bringing the feature to its Prime Instant Video service, starting with its original series, later this year. But, not surprisingly, Amazon fails to lay out why we'd want to watch everything in HDR. The company claims that it will offer better contrast and "detailed shadows and distinct highlights to make colors appear richer," but judging from HDR demos we saw at CES, it's not an aesthetic appropriate for everything. Amazon isn't the only company hyping it up: Netflix also demoed 4K HDR video at CES, and its chief product officer Neil Hunt even considers it "more important" than 4K.
