The "fisheye" lens is a real romance of photography

In the art of photography there are many interesting andunusual solutions and tricks that allow you to not only accurately and beautifully display all the beauty of the world, but also to create real masterpieces. Some of them are so fantastic and wonderful that they look like fabulous magical paintings. But the real art is not to change the image beyond recognition, but only to give it a special charm with the help of small tricks.

A fisheye lens is a wonderful find likefor amateur photographers, and for professionals. It has a maximum angle of view - 180 °, and the distortion that is present when shooting, gives an interesting and original effect.

The principle of operation of the lens, its varieties

The name of the lens "fish eye" got in1906 Robert Wood noted that the way the image is obtained with its help, the fish sees the surface of the earth from under the water. A similar picture we see in the door peephole. Distortion (distortion) occurs very strongly, only a small zone in the center more or less corresponds to its real parameters. Used it earlier in meteorology, only to see the entire celestial sphere.

It is interesting that now such a lens is usedin scientific works, when there is a need to increase the maximum viewing angle. And for photo amateurs, he became a wonderful find, with which you can create original landscapes or architectural works, funny portraits and much more.

A fisheye lens is of two different types.The first of them is called circular, or circular. He gives a complete picture in the form of a circle, creating an original image. The angle of view is 180 °. But, in fact, it works in the same way as other lenses, capturing only part of the sensor — a rectangle that fits in the diameter of the lens itself. This rectangle and then becomes a round image. Usually produce such a plan accessories for 35 mm format. Their focal length is 8 mm.

What else could be a fisheye lens?The second option is called a diagonal, or full-frame lens. In this case, the entire sensor area is used, and the angle of view is 180 ° only diagonally. It will be approximately 147 ° horizontally, and 95 ° vertically.

Lens types are divided rather arbitrarily - alldepends on which part of the sensor to use. Therefore, a standard fisheye effect lens can give any kind, the difference will be only in the size of the sensor itself. These accessories are quite expensive, and sometimes try to replace them with simple converters. The converter is worn on a conventional lens, dramatically changing its viewing angle. They allow you to take wide format images on any camera. At the same time, in order for the image quality to be good, it is necessary to shoot at a small aperture.

How to shoot with a fisheye lens - the basics of literate photography

Big plus of this type of lens - no problemwith image focus. Due to the large area of ​​contact with light, the picture is very clear and expressive. The central lines (horizontal and vertical) are not distorted.

The effect of "fisheye" looks very nice when photographing the sky. In the forest, between houses, or simply the sky dome itself can be photographed with a circular lens.

Wide format image allowstake pictures near objects of architecture. In order to make a picture harmonious, you need to try to observe its frames - to connect horizontal or vertical lines with even elements of the structure.

Funny portraits or just funny photosare obtained when shooting with a fisheye lens. The central zone is less distorted, so it is there that the main objects of the survey should be placed. Four corner zones - areas of maximum distortion.
