A hood also known as lens hood helps get better photo quality by reducing or stopping the surplus light from entering the camera lens. The theme behind this lens hood is that it can lower the contrast of the image. It reduces lens flash when images are captured in bright light or when there is back lighting.
Camera lens hood come in different material, sizes and shapes: rubber, plastic and metal. Rubber lens hood is generally collapsible. Collapsible hoods are easy to carry, need less space and metal hoods provide better protection.
Many cameras have integral or accessory lens hood. Several manufacturing companies include a lens hood while buying a camera or these lens hoods can be ordered separately. Generic lens hood can be bought by the third party.
Why Use A Lens Hood?
Lens hood not only stop the light coming into the lens at extreme angles but it also allows to shoot towards the light source, so long as it is kept outside the image area, without unnecessary flash.
To protect against lens flare lens hood is fixed onto the end of the lens. Lens flare might happen when the lens is faced towards a bright source of light. It can be caused via the inner reflection and refraction of light in the optical parts of the camera lens. The sun might be bright for the lens and it could easily damage the picture. When bright light shines on the lens, but not in the field of view, the flare produced is usually a haze that can wash out the camera's image and reduce its contrast.
To avoid this effect you need to shade the lens with a hood or by holding an object or your hand between the source of light and the lens. This will effectively cut out the flare.
Lens hoods should match to the angle of the view of the lens and eliminate as much light as possible without being noticeable in the picture.
