Lens Hood

The Lens hood for Digital SLR camera is used to reduce glare, especially when your light source is near the front of the camera. This results in improved image contrast. It also serves as an added protection for the front element. Some people who use the lens hood, claim, they do not need a lens filter which can increase internal reflections when shooting with a backlit source or shooting towards the sun. The choice is yours, I personally use both.
