--What is HDR Timelapse? To the best of my knowlege, this is some of the first real world high dynamic range video.  Utilizing a computer controlled DSLR camera, motion control mechanics, and HDR software, I've perfected a method that results in true 32-bit radiance frame sequences.  HDR is nothing new and computer generated imagery professionals have been producing 32-bit video for years now but, video sensors that can capture true HDR are still in their research and development stages.  By capturing clusters of multiple exposure levels (brackets) at timed intervals (timelapse) and batch processing the clusters into single HDR radiance frames I am exploring a transitional high dynamic range video solution. --What am I looking at with the sample videos? Currently, there are only a handfull extremely expensive HDR displays, I've tone-mapped the sample videos compressing them down to today's standard 8-bit range.  The original frames are true 32-bit and 1080i resolution.  "MILapse" is my experimental timelapse video channel on youtube where I share my experiences with other timelapse enthusiasts - check it out to see an expanded scope of my timelapse work: www.youtube.com/milapse --Can I purchase the HDR video? Absolutely! I've provided HDR Video researchers with data sets and I'm equipped to provide commission work to fit your needs and specifications.
