One from the archives: It’s a great pity that in order to enjoy the benefits of digital imaging, we must use pixels that may only be one of a comparatively small selection of colours, as opposed to the effectively infinite subtlety of nature. Phil Rhodes spreads light and understanding about quantization and noise.

    Why conspiracy theories rarely work out http://www.redsharknews.com/technology/item/3204-why-conspiracy-theories-rarely-work-out http://www.redsharknews.com/technology/item/3204-why-conspiracy-theories-rarely-work-out Why conspiracy theories rarely work out

    AKA: Yes, we did land on the Moon. It’s often been said that the problem with keeping conspiracies under wraps lies with the amount of people that would have to be involved, and now there’s a mathematical formula that describes it.

You might need one of these...

      Can you buy a complete computer system off-the-shelf (or online) that keeps up with modern 4K video editing requirements? H. Paul Moon reckons you can.

        How to understand "Log" or Cine-style recordings http://www.redsharknews.com/technology/item/1975-how-to-understand-log-or-cine-style-recordings http://www.redsharknews.com/technology/item/1975-how-to-understand-log-or-cine-style-recordings How to understand

        Replay: Modern cameras have incredible dynamic range - but you can only access it if you use a "log" or "Cine-style" mode when you record. Phil Rhodes explains how this works, and wonders why there are so many non-standard ways to do it!

          Why 4K to the home is not going to happen this year http://www.redsharknews.com/technology/item/3188-why-4k-to-the-home-is-not-going-to-happen-this-year http://www.redsharknews.com/technology/item/3188-why-4k-to-the-home-is-not-going-to-happen-this-year The Netflix globe: now mostly covered, now mostly slow

          The sensible conclusion that many people reached after CES was that you would not want to buy a television set that was anything but HDR 4K. Latest figures show that it’s going to be a long time before broadband speeds can deliver that content, however.

                Hydrogen fuel cells for drones and film production? http://www.redsharknews.com/technology/item/3153-hydrogen-fuel-cells-for-drones-and-film-production http://www.redsharknews.com/technology/item/3153-hydrogen-fuel-cells-for-drones-and-film-production Hydrogen fuel cells for use by film professionals?

                We explore the topic of hydrogen fuel cells and discover that there are significant hurdles that must be cleared before it makes sense for use on film sets (and most other places).
