WEEKLY VOCAB: LENSES

FISHEYE: a camera lens that has a wider than normal angle of view (and usually a short focallength); it produces an image that is foreshortened in the center and is more distorted in the periphery.




MACRO: A macro lens lets one take sharp, detailed photos of very small object. Its zoom feature is very high quality.

TELEPHOTO: The camera lens has a narrow angle of view, and a longer than usual focal length. The effects of a telephoto lens are similar to using binoculars; the image is magnified making the subject seem closer than it actually is.
