The great thing about digital cameras is that you can take almost unlimited shots and don’t have to worry about cost. Take loads of shots at different settings and you’ll find yourself learning as you go and honing in on what works best in the situation you’re in.”This is a really helpful and interesting article directly pertaining to what I want to be doing with my new camera.
