This video, from San Francisco based Soviet Montage, highlights several clips made using their new High Dynamic Range (HDR) process.
Video is recorded on two Canon 5D mark II DSLRs, each capturing the exact same subject via a beam splitter. The cameras are configured to record different exposure values, e.g., one camera is overexposed, the other underexposed. In post, a variety of HDR processing tools are used to combine the video from the two cameras.
HDR video allows for even exposure where artificial lighting is unavailable or impractical. For example, when a subject is backlit, one camera could be set to expose the subject, the other the sky, resulting in video with perfect exposure throughout.
