ISO seems to be a much more complicated topic than it needs to be really. I see so many questions about ISO posted online from confused new camera owners that it makes me wonder when it got so complex. But it’s really not that difficult to grasp, really, when it’s broken down and explained.

In this video, photographer Dave McKeegan walks us through ISO, explains the terms and elaborates on some of the tech so that you can understand the differences between base ISO, native ISO and extended ISO. He also explains what the hell dual native ISO is, how it works and how it can benefit you as a creative.

This is the best explanation on the Internet about what dual ISO is and how it affects dynamic range

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.
