What ISO setting to use? High is good for shooting without blur or shooting in the dark but gives you noise (“grain”). What is optimal?
The following may help.
If you do not use AUTO ISO, my rule of thumb for starting points is:
- Outdoors, or when you are using a tripod: 200 ISO
- Indoors: 400 ISO (whether or not you are using flash)
- Problem light, such as museums or hockey arenas: 800 ISO
You can vary from there of course, but you will not be far off.
Here’s an 800 ISO handheld image (it won me a media award):
