The phrase “dual native ISO” seems to be coming to more and more cameras these days. Certainly not to all of them, but to many, especially when it comes to video. Panasonic’s done it with the GH5S, Blackmagic’s done it with the Pocket Cinema Camera 4K, and it’s out there on a few more, too.
But what exactly is it? I mean, we get what the end result is, but how does it work? What is this voodoo? And how does it really affect how we shoot? John Hess from Filmmaker IQ dives deep into dual ISO and the effect it has on dynamic range with the BMPCC4K in this video, and it’s probably the best explanation I’ve seen so far on how it all works.
