For most of what I shoot, high ISO performance isn’t really much of a concern. It’s rare that I need to go above ISO400, usually. But with today’s cameras having ISOs that go up into the multiple hundreds of thousands, what’s the point if going that high degrades the image so badly that it’s pretty much unusable?
That’s the topic that music and sports David Bergman explores in this video. Cameras and their crazy high ISO values, what’s the point of them and when and why you might want to use them.
