The lower the iso the faster the shutter speed.Could someone please explain ISO to me? Thanks!
Not necessarily. It's one part of the exposure equations which involves ISO, shutter speed and aperture.The lower the iso the faster the shutter speed.
The lower the iso the faster the shutter speed.
All praise to the holy trinity.... Can I get an Aye MEN?

In ancient history (the 50s) when I was first learning photography with an SLR, film speed was rated as ASA, now ISO. Then, ASA 100 colour was a super fast film & one needed a shutter speed one stop less than ASA 50 film for a given aperture. Methinks this post is ass-backwards.
Ron, who used ASA 12 Kodachrome for slides.

I'm going to paraphrase here. I got this definition from Understanding exposure: Think of iso as bee's. If you have a set amount of light to collect, and 200 bee's can do it in say 4 seconds, then if you double that and have 400 bee's you will be able to collect the same amount of light in 2 seconds or half the time. Does that make sense?
