The Quadrant Video Shoot – HDR timelapse experiments with CHDK

In Uncategorized on May 16, 2011 by Admin Tagged: , , , , , , , , , , , , ,

These are some fragments from a HDR timelapse shoot at The Quadrant, a serviced office space in Sheffield, UK. Below are some short examples of HDR timelapse video created with Canon PowerShot cameras “hacked” with the Canon Hack Development Kit (CHDK), an open-source software program. The HDR is achieved by shooting 3 exposures for each shot, one normal exposure, one +2 EV and one -2 EV. The results are post-processed with Photomatix into tone-compressed jpegs, the result of which is to produce an image with a much greater colour depth. These are then compiled into movies using QuickTime Pro. The result is a moving image that can accommodate a very high dynamic range without losing either the highlights or the shadows. It’s very processing-intensive but the results are impressive and produced with domestic-scale equipment (and a lot of patience).

Watch them in 720p HD on Vimeo or YouTube and stay tuned for a proper edit. Music by Sieben aka Matt Howden.
