Space Monkeys, Raw Video, and Giving Us All You've Got


This is a brief excerpt from ProLost




The team at Magic Lantern have managed to hack the Canon 5D Mark III to record 14-bit raw 1080p video at 24 frames per second. The results are stunning—the highest-quality video we’ve seen from a DSLR yet, comparing favorably to images from cameras costing much more.

This is a big deal. But maybe not as big a deal as some have made it out to be. Like Ham, the chimpanzee that was launched into space on a Mercury rocket, the Magic Lantern raw hack is less notable for its discrete accomplishment than for what it portends.

Key ingredients:
