Yes, the source for the still above is a 1080p 14bit RAW shot with the 5D mark III with Magic Lantern!!! And here’s a test video showing you how that looks in motion with an article elaborating the work with the camera: LINK.
The developers working on the Magic Lantern hack for the Canon 5D mark III have enabled continuous 14bit RAW recording last year. We tested it and it works great. The resulting images are totally breathtaking for a DSLR. The installation procedure has now been strongly simplified.
Please follow our complete dummies guide to squeeze the RAW bits out of a Canon EOS 5D mark III.
NOTE: We take no responsibility for what happens when you follow our guide. Do it at your own risk and research on your own if you want to make sure.NOTE: When installing Magic Lantern your camera will start up 2 seconds slower (this can now be undone by simply uninstalling Magic Lantern)
