Things You'll Need
Instructions
Evaluate the scene you are about to photograph. If you have control over where your subjects or subject is going to be placed, then pick an optimum location where the sun will be behind the plane of the front of the lens. As long as the sun angle does not cross the front of the lens, no sun flares will appear in your picture.
Attach a lens hood. Lens hoods are designed to prevent unwanted light from entering into your lens. Lens hoods are specifically designed for the lens you are using. If the lens hood is not designed correctly, it may appear in your picture.
Position your hand or a piece of cardboard to the side of your lens. If you cannot control the location of your subject and your lens hood is still letting light into your lens, use your hand or a larger piece of card or cardboard to block the light. When doing this, look through the viewfinder to make sure your hand or cardboard does not appear in the picture.
