Congratulations on the new camera! After you get some of the basics down, you will enjoy photography. There are some very basic "rules of thumb" that you could learn, but for now, just concentrate on learning your camera. Beginners can jump right into "manual mode" right away, but IMO you'll have a long learning curve unless some experienced photographer is at your elbow mentoring you as you go. Do this: Set your ISO to "auto" (in the menus). Set your mode dial (on top) to "auto". Go outside and take a picture. Now, look at what your camera set for those conditions. My guess it will be something like f/11, @ 1/1000 of a second (or thereabouts). Now you have a starting point for the next time you want to try manual mode. Whatever the settings were, is but a good starting point. If there is snow and bright sunshine, you should override your camera's settings just a bit, to cut back on the exposure, but that could be for another day. "Auto" (the green auto) will work in most situations, possibly even inside, but don't expect miracles. Later, you will learn to select either the shutter speed or the aperture, and you're that much closer to fully manual.
