Understand Wide Angle Lenses

Stepping up to a wide angle lens expands the boundaries of your photography. A wide angle is defined as any lens with a focal length of less than 50 mm. Pictures shot with a wide angle capture a broad area of view. Although most frequently employed for shooting landscape images, a wide angle lens may also be used to capture close subjects, often resulting in unique compositions.








Instructions








1. Most "point and shoot cameras" offer a zoom lens incorporating wide, normal and telephoto focal lengths. For shooting professional quality photographs, a single lens reflex (SLR) with an interchangeable wide angle lens is preferable to a "point and shoot" camera.


2. A wide angle lens may be fixed, having a single focal length (as in 24mm); or it may be a zoom with a variable focal length (as in 12 to 24mm). Although not offering as much flexibility, a lens with a fixed focal length can result in a sharper image.


3. Wide angle zoom lenses are divided into regular wide angles, super wide angles and fisheyes. A regular wide angle zoom has a focal length of 24 to 35mm, a super wide averages 12 to 24mm; and a fisheye, is often between 8 to 10mm.


4. A wide angle lens provides a greater depth of field which is defined as the range of the photo that is in sharp or acceptable focus. Using a wide angle with a smaller lens opening or f-stop will produce a photo that is entirely in focus from foreground to background. Employing this technique with landscapes contributes to creating an excellent sense of place.


5. It is important to adhere to the rules of composition because a wide angle lens results in a vast view. As with any picture, your photo must include a strong focal point to be artistically successful.
