Join Derrick Story for an in-depth discussion in this video Understanding ISO, part of Getting Pro Results from a Compact Camera.
ISO controls how sensitive your camera is to light.…So when you're outdoors and there are lots of light that ISO setting can be low.…It can be around 100, no problem at all.…Once you move into lower light, such as moving indoors or the ambient light is less, …then you are going to want to raise that ISO up a little bit more to make…your camera more sensitive to that lower light.…Now when you're indoors, there are a couple different ways that you can deal…with that low light.…You could raise the ISO up, as we are talking, or you could turn on the flash…and take flash shots, and that's what most people normally do.…
The problem with flash all of the time is that light is harsh.…You know what that shot looks like. Very bright on the subject, very dark on the background.…The other problem is that it can reflect in mirrors and glass and that's…unwanted aspect of the shot.…So sometimes it would be nice to turn off that flash and just go with the…existing light and that's where ISO becomes really important.…
