I thought we could start a photography help thread...people who have questions about their camera or some functions can post here and get help. I know there are a lot of skilled photographers here.

I have a couple questions.

How do you know what level of ISO to use? Like, would you use a high ISO setting in a bright setting? Or a darker one?

What's the best way to capture details/colors? I've seen some photos and it's like, wow, so many colors and stuff. I KNOW my cameras are capable of taking awesome photos, I just can't figure them out.
