ISO-Invariance and Dual Native ISO in Photography

The ISO is the most misunderstood setting on your digital camera. To make things even more confusing, some camera sensors are considered "ISO invariant," meaning that raising the ISO will give the same effect as increasing the exposure in post-processing. Add the fact that many of these cameras also have dual native ISO, and you have a confusing mess. In this video, we'll break down ISO invariance and dual native ISO to help you determine the best ISO to use in your photography.
