In the art of photography there are many interesting andunusual solutions and tricks that allow not just accurately and beautifully display all the beauty of the world, but also create real masterpieces.

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.

The fisheye lens is a wonderful findfor 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 the lens, its varieties

Its name "fish eye" got1906 year. Robert Wood noticed that as the image with his help turns out, 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 meets its real parameters. Used it earlier in meteorology, only in order to see the entire celestial sphere.

It is interesting that even now such an objective is usedin scientific works, when there is a need to increase the maximum viewing angle. And for amateur photographers, it has become a wonderful find, with which you can create original landscapes or architectural works, funny portraits and much more.

The fish eye lens is of two different types. The first of these is called circular, or circular. It gives a full picture in the form of a circle, creating an original image. The angle of his sight is 180 °. But, in fact, it works in the same way as other lenses, capturing only a part of the sensor - a rectangle, which is placed in the diameter of the lens itself. This rectangle becomes a circular image later. Usually they 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 diagonal, or the lens of the full frame. In this case, the entire area of ​​the sensor is used, and the angle of view is 180 ° only diagonally. It will be approximately 147 ° horizontally, and 95 ° vertically.

Separate types of lenses are rather arbitrary - alldepends on which part of the sensor to use. Therefore, the standard effect of the "fisheye" lens can give any kind, the difference will be only in the size of the sensor itself. These accessories are quite expensive, and sometimes they are tried to replace with simple converters. The converter is put on a usual lens, sharply changing its viewing angle. They allow you to take pictures of a wide format on any cameras. In order to make the image quality good, you need to shoot at a small aperture.

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

A wide format of the image allowstake pictures near architecture objects. To make the image harmonious, you should try to observe its framework - to connect horizontal or vertical lines with even elements of the structure.

Funny portraits or just funny photosare obtained when shooting with a fish eye lens. The central zone is less distorted, so it is there to place the main objects of shooting. Four angular zones are areas of maximum distortion.
