LENS
The lens is a device consisting of several mirrors that function change the object into the shadow, inverted and real. The lens is located in front of the camera.
There are several types of lenses: - Normal lens - The lens width (wide) and .. - Long lenses or commonly called a telephoto lens.
Normal-sized lens focus as long as 50 mm or 55 mm to 35 mm film size. Point of view this lens is similar to the human eye viewpoint. In addition to a wide lens, there is also a telephoto lens.
Wide lens usually has a focus 16-24mm wide. These lenses are suitable for taking pictures of landscapes. Telephoto lens is a lens that has a long focal length. This lens can be used to obtain sharp short space and can generate near-real facial perspective. These lenses are usually the size 85mm, 135mm and 200mm.
Usually photographers use lenses as needed. If you want to photograph objects or objects near, or photographing the scenery, they usually use a normal lens or wide-angle lens.
But when the photographer wants to capture a particular moment with long distances, usually they use a telephoto lens. Thus, they do not have to bother to target objects, and their work will be more easy. In addition to the normal lens and a telephoto lens, there are also other types of lenses commonly referred to as lens variations or special lenses (special lense). Usually these lenses are used for specific purposes. For example fish-eye lens (fish eye lens - 180 degrees). Taking photos with this lens the photographer will get a unique result. However, this lens does not function to filter out anything except change the view to achieve the results that deviate from the usual shooting.
If photographers want to take objects with small size or shooting close (photographer closer to the object), commonly used lens is a macro lens. These lenses are usually also used for reproductive purposes because it can provide excellent quality and minimal distortion. For example: to photograph flowers, insects, etc..
In addition to equipment, to produce a good photograph we also must consider several matters, among others: composition, light, line, shape, texture, appearance, color and vertical or horizontal.
