How can photographers reduce lens flare?
By using a lens shade, changing the camera angle when shooting toward strong light sources, and by shooting from a shaded area or in the shadow of an object. Shadows can be produced by positioning a hand, a piece of paper, a hat, etc. above or to the side of the lens to block or reduce the amount of problematic light entering the lens. Other ways to reduce lens flare are to keep lenses and internal parts of cameras clean and, when shooting into the sun, keeping the sun near to the center of the frame.
