what are all the little features I get on my dial when using my Nikon Coolpix 4600, there's what looks like a man running, a mountain, a woman wearing a hat, and a head with a star by it, and a selection called scene. I have no idea what any of these are used for, and I stick to the normal camera icon. I'd like to know how to use these, I think it would improve the quality of my photo taking experience.
