Very wide-angle lenses allow photographers to produce an image composed of a large number of objects and to frame very large subjects (such as buildings) at close proximity, and to photograph objects on different geometrical planes that can be very far apart. Such lenses also accentuate perspective, with the most noticeable result being the distortion of straight lines. |
