Not sure what lens you are using but there is a good rule to go by when you are starting out like you are. When hand holding your camera the shutter speed should match or exceed the lens focal length. In other words if you wanted a sharp, shake free shot with a 50mm lens your shutter speed would be 1/50th sec or faster. If you are using the 18-55 that came with the camera then for now till you know more about photography I would not shoot slower than 1/60 sec for any reason. 1/90sec would be better. No need for a tripod at these speeds. Set you ISO to auto with the max a ISO1600 and minimum shutter speed at 1/90sec and that is done in the same place in the menu as AUTO ISO. Set the camera to P for Program for now just to get a letting experience and get used to getting a few good shots. MAster this and then move on to more advanced techniques
