Hi there, I am a rookie in photography, but guess what, I have been given an awesome gift of a Nikon D 300 Camera. Hmm, I have tried using the camera based on what the product manual recommends. However, I realize that in most of the photos I take, the background gets into a sharp focus whilst the target is blurred. I would be elated if anyone could help me with a step by step approach to setting the camera for effective use for three main settings. Sunny day Soccer photography, indoor still usage and soccer photography at night times (under floodlights). My camera comes with two lenses, 70-300mm (1:4-5.6G) and 18-135mm (1:3.5-5.6G ED).
