Expected to be included with the Lumia Denim update, version 5 of the Lumia Camera app will bring incredibly fast speeds, allowing you to take picture after picture just milli-seconds apart. Moment Capture, which starts with a long press of the camera button, will allow some models to start filming 4K quality video at 24fps. High quality 8.3MP images from the video will be available as individual photographs. Improved image processing algorithms will allow for clearer pictures overall.
The Lumia Denim update, which still could hit some Lumia devices before year end, will also include an improved Glance Screen. In addition to viewing the time, date and notifications, you will be able to choose between Bing Weather, or Bing Health & Fitness data. Also coming with Lumia Denim is the update that will allow you to wake up Cortana by saying the verbal cue, "Hey Cortana".
