Intel has announced the 'A Momentary Lapse' competition, seeking entries that can then be used to advertise its products. Prizes include Dell XPS Ultrabooks and Canon DSLRs, with the chance to win an EOS 5D Mark III. To promote the competition, Vincent Laforet has made a 'How to make time-lapse photography' video tutorial. Both the stills and video (time-lapse or slow-motion) competitions require entries around the themes 'music, style, entertainment or sports,' and are open to residents of the USA and Canada. The competition offers $50,000 worth of prizes, spread across 18 weekly stills contests and three 40-day video contests.
