You don’t usually hear the phrase ‘astounding coin animation’ these days do ya? Have a look at the video all the way to the end, the makers show the secret behind how it was made. No elves were involved, I promise! (I like the old PET computer in the background. nice!)
Anyone who regularly uses a video camera will know that the devices do not see the world the way we do. The human visual system can perceive a scene that contains both bright highlights and dark shadows, yet is able to process that information in such a way that it can simultaneously expose for both lighting extremes – up to a point, at least. Video cameras, however, have just one f-stop to work with at any one time, and so must make compromises. Now, however, researchers from the UK’s University of Warwick claim to have the solution to such problems, in the form of the world’s first full High Dynamic Range (HDR) video system.
I see this and I feel that I’ve been seriously slacking off! ‘Denis MO’ have been thinking of building his own camera for many many years and finally decided to act on his dreams. His original camera design is loosely based on Russian cameras (Zenit, Zorki, etc) and can use common Russian lenses (Industar, Helios, Mir) and has a variable shutter that can be set to 1/30, 1/60, 1/125, 1/250, and bulb. After about 500 hours of planning and machining he now has a fine camera that takes a pretty good picture.
Shoot the same scene through a beam splitter on two Canon 5D MKII digital cameras. Under expose one camera by two stops, over expose the other by the same. Mix in post with some custom software that compresses the brights and shadows and you have what will probably become the next over used video effect, once the hardware gets sorted out… Read the rest of this entry »
Recording motion in the form of moving pictures has gone through many stages. It started out as chemically processed film and was eventually replaced by analog magnetic tape. As time passed and technology advanced, the magnetic tape was replaced by digital memory devices with no moving parts and a much lower cost. Read the rest of this entry »
