If you’re looking to buy a new camera, you’ll probably see the terms “original ISO” and “basic ISO” thrown around. ISO, as one of the three basic exposure parameters, is a term all photographers should understand. This great video tutorial will explain the difference between base ISO and base ISO and the consequences of each for your photography.

Coming to you from David Bergman with adorama television, this helpful video tutorial will show you the difference between the original ISO and the original ISO. In the days of film, ISO simply referred directly to the sensitivity of the film you were using and was easy to understand, but in the digital age it’s much more nuanced. Most digital sensors really only have one level of sensitivity. When you change the ISO, what you are doing roughly is changing the amount of post-sensor gain applied to the signal, unlike film, where if you change the ISO by swapping the cartridges, you actually the direct change in sensitivity. In fact, this difference shouldn’t really affect your day-to-day work as long as you understand the consequences of increasing ISO on image quality, but it can still be quite helpful to learn more about how to do this. how ISO works. Check out the video above for the full recap from Bergman.
