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.
