What is a Lens Hood & why every camera needs one !
Experienced photographers often use lens hoods; these are useful when trying to remove strayed light from entering the image area. This article will explain the various types of lens hoods and their capabilities, and how a lens hood works as an extension of a camera lens. The hood serves two main functions, firstly to provide shade to the top of the camera lens. This is useful to obstruct any unwanted light from entering the lens, removing the risk of flare and unwanted low contrast photography. With this function, the lens hoods can create a sharper, deeper contrasted image when additional light is removed from image area.
Secondly, lens hoods are great protective gear! Protecting your lens is critical in photography for shooting up close and personal, or if you have an expensive lens or UV Filter you want to protect. A lens hood is an effective way to protect your camera parts while on the move.
There are two common types of lens hoods available. The first is the petal lens hood, which have curved cut outs on each side of the lens hood. Its purpose is to not allow the lens hood to distort a wide angle shot, yet still assist and protect. This design is useful for wide angle photography because the hood won't be in the image area even when zoom is applicable.
Secondly, a round lens hood is more traditional and used for a more narrow depth of field, reducing the amount of lens flare. The shape of the lens hood is often matched by the type of lens used.
Lens hoods are an affordable piece of equipment all photographers should add to their kits! They are capable of conserving important aspects of the image area like contrast and saturation levels. It is an effective piece of equipment that can reduce the amount of photo editing software required to recover missing details of the picture.
How To Use:
When traveling, try attaching the lens hood in reverse to save space and pack more equipment.
The pop up camera flash is not capable of illuminating the image area, usually because the light is being shaded by the lens hoods. On-camera flash is best when using a lens hood because it adds additional height to where the light is being reflected.
Experienced photographers often use lens hoods, and we hope this article they are such an important part of a photographer's kit.
