Auto ISO is a great feature, but use it wisely. Here’s when NOT to set your DSLR to “Auto”:
- When using a tripod: you want low ISO then.
- When shooting in a studio setting: same, low ISO
- When using flash at events: dfoit yourself and select 400 or 800 as your starting point (and go higher if you need)
- When shooting sports: your camera will go to a low ISO: you should go to 1,600 ISO instead.
My most expensive camera does not have auto ISO – you do not need it. I like having it, but I can live without it.
My starting points: 200 ISO outdoors, 400 indoors, and 800 in tough light (sports, museums). And then vary from there.
