I’m working on a full review for the Sony RX100 IV but I’ll share a couple of video samples shot with the camera using the SLOG2 profile in 4K and a variety of slow motion frame rates. Above, you see a run-through of ungraded and graded clips (starting with the SLOG2 LUT) for a variety of low-light scenes. [Read more…]
High Speed Video Developed for Frame Rates of 250,000 FPS
Scientists at Oxford University have developed a method for capturing extremely high frame rates by expanding on existing consumer-grade photography and video camera technologies. The new capture method works by using a single sensor to capture images simultaneously. According to Dr. Gil Bub,
“This is done by allowing the camera’s pixels to act as if they were part of tens, or even hundreds, of individual cameras taking pictures in rapid succession during a single normal exposure. The trick is that the pattern of pixel exposures keeps the high resolution content of the overall image, which can then be used as-is, to form a regular high-res picture, or be decoded into a high-speed movie.”
The most interesting aspect to this new development is the relatively low cost. While the scientists developed the technology with medical and scientific applications in mind at macroscopic and microscopic levels, the underlying hardware is primarily what we use in consumer-grade cameras. As a result, patent licensing of this tech could see future consumer applications but, obviously, at lower than the extreme frame rates required for use by the scientific community.
