Those part of Magic Lantern are always hard at work tinkering away to give us mere mortals better cameras at zero cost. They were able to pull a rabbit out of a hat and give us RAW video on Canon DSLRs, which is a huge step up on video quality from the standard H.264 files the cameras normally record to. Now they’ve got another trick up their sleeve that can actually improve dynamic range about half a stop — but there are some caveats at this early stage.
