Lens hoods are often designed to fit onto the matching lens facing either forward, for normal use, or backwards, so that the hood may be stored with the lens without occupying much additional space. For wide angle lenses, the length of the hood cannot be as long as those for telephoto lenses, as a longer hood would enter the wider field of view of the lens. Lens hoods are more prominent in long focus lenses because they have a smaller viewing angle than that of wide-angle lenses. This allows the lens hood to block stray light with the higher portions of the lens hood, while allowing more light into the corners of the image through the lowered portions of the hood. The geometry of the lens hood can vary from a plain cylindrical or conical section to a more complex shape, sometimes called a petal, tulip, or flower hood. This stray light often comes from very bright light sources, such as the sun, bright studio lights, or a bright white background. Flare occurs when stray light strikes the front element of a lens and then bounces around within the lens.
