Playing with different lighting conditions can improve your shots. For one, shoot with the sun at your back to get even lighting on your subject. This makes your subject front-lit, helping you avoid shadows on faces and bring out more detail. Sometimes you may not be able to change your stance, so look for a Canon camera that offers Intelligent Auto which automatically identifies a variety of different scenes and makes adjustments automatically from a bright sunny day, sunset or a cityscape at night.
