After you learn the basics of the camera, then that's where the fun begins with using the composition, lighting, and background choices etc. I take lots of people pictures, mostly outdoor candids in the Portland, Oregon area. Lately I like to find events or activities and mix in with the people. If you are upfront with taking the pictures with them, most don't mind and you can get some of the best photos. I have people ask me to take photos of them sometimes too.
I'm mostly over at the Olympus Talk Forum...there we discuss more about general photography rather than just gear. A lot of us have been at that forum for years. If you would like...share your photos there too...we'd be glad to help.
Here's a recent one taken on a cloudy day along our waterfront with the settings that I used. We've had such rainy and cloudy weather...hard to get any sunny pictures lately.
