Lens flare can appear as a general haze across the picture that lightens it reducing contrast. It can also appear as streaks across the picture or shapes, usually circles, in the picture.Flare is commonly associated with sunlight, but can occur as the result of any bright light in the area. How to Avoid Lens Flare
Avoiding lens flare can be quite simple. Here are some easy tips.Shield Your Lens from the Sun
You can shield your lens from the sun to make sure that the glare doesn't hit its glass elements. The easiest way to do this is with a lens hood. A lens hood is a cylindrical peice of plastic that screws onto the end of your lens. They can have a straight or tulip-style edges.If you don't have a lens hood with you, you can improvise by shielding your lens with your hand or a piece of paper.
Use a Prime Lens
Prime lenses usually produce less flare then zoom lenses because they contain fewer glass elements. The more glass in your lens the more opportunities for light to bounce around inside it.If you are using a zoom lens, you'll find that changing the focal length can reduce flare some. Try taking the picture at different focal lengths to see if you can minimize flare.
Watch Your Composition
Taking your picture in the direction of the a bright light like the sun will increase the occurrence of flare. Having the light in the picture or even just out of the frame can cause streaks and haze in your photo. Compose your picture so that the sun or other bright lights are well out of frame.
