This is a great, exhaustive tutorial on managing color gamut for photographers by color expert Andrew Rodney. He does a great job making the case for working in wide gamut color spaces like Pro Photo, especially when capturing in RAW. Using smaller gamuts like sRGB throws away useful color data that printers and more and more displays can recreate.
Had a great interview yesterday with VentureBeat’s Dean Takahashi on Nanosys‘ high gamut display technology called QDEF (you can read the full story here). Since we talked a lot about the difference in color performance between the various displays here in our demo room I thought it might be useful to post this comparison chart. Typical tablets can display about 20% of the range of colors an average human eye can perceive while QDEF enabled displays show over 60%:
Recently returned from a week in rainy Indianapolis at CEDIA 2011 and thought I’d share some of my observations.
Amidst the din of the latest audio systems and blue-tinged glare of LED driven LCDs I discovered a small but growing group of companies talking about color.
While the mainstream, average show-goer was talking a lot about contrast or dynamic range, discussing the difference between sets with ‘grey levels’ and those capable of true ‘black levels,’ I’m predicting that color will dominate next year’s show. With high color gamut panels just around the corner, we’re just starting to see a technology ecosystem emerge around delivering an improved color experience for consumers. Several companies (like SpectraCal and Entertainment Experience) that I talked to are developing powerful color ‘upscaling’ technologies that will help to bridge the gap between today’s content and the eventual availability of high gamut formats, like P3, at the consumer level.
Another great, potentially high color gamut-enabling demo I saw was THX’s Media Director. These guys are using metadata to automatically set-up and optimize home theater equipment to the content you are watching. By working with and providing tools to the content creators, what the end user sees and hears should be much closer to the original artistic intent. Seems to me there’s great potential for this technology as consumers start watching content across a wider variety of displays (with wildly varied performance characteristics from HDTV to low res, low gamut smartphones to soon to emerge ‘retina’ resolution computer displays) than they have in the past.
At the next CEDIA we ought to hear people talking about true reds and greens compared to the orange-ish and yellow-ish hues of last year’s sets.
