When you want to capture a wide-angle image, the fisheye lens provides the ability to include a large field of vision. To do this, however, it utilizes a hemispherical shape, similar to the eye of a fish, in order to capture an extensive radius. When viewing the printed image, the center will appear close to normal but the outer elements will appear very distorted.
- Use a fisheye lens for special architectural effects when capturing a large building. Try composing the frame with an image in the foreground and use the sloping background to enhance the theme. For instance, using a fisheye lens when shooting a tulip field in Holland adds interest when foreground flowers feature prominently and a quaint windmill farm frames the background.
