In the art of photography there are many interesting and unusual solutions and tricks that allow not only to 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.
The fisheye lens is a wonderful find for both amateur and professional photographers. It has a maximum angle of view of 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 fisheye lens was named in 1906. Robert Wood noticed that the way the image is obtained with it, the fish sees the surface of the earth from under the water. We see a similar picture in the door peephole. Distortion (distortion) is very strong, only a small zone in the center more or less corresponds to its real parameters. Used it before in meteorology, only to see the whole celestial sphere.
It is interesting that even now such a lens is used in scientific work, when there is a need to maximize the 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.
There are two different types of fisheye lenses. The first of them is called circular, or circular. It gives a complete picture in the form of a circle, creating the original image. The angle of his vision is 180°. But, in fact, it works in the same way as other lenses, capturing only part of the sensor - a rectangle that fits into the diameter of the lens itself. This rectangle then becomes a round image. Typically, accessories of this kind are produced for the 35 mm format. Their focal length is 8mm.
What else could a fisheye lens be? 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.
The types of lenses are divided rather conditionally - it all depends on which part of the sensor to use. Therefore, a standard 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 try to replace them with simple converters. The converter is put on a regular lens, dramatically changing its viewing angle. They allow you to take wide format pictures on anycameras. At the same time, in order for the image quality to be good, you need to shoot at a small aperture.
How to shoot with a fisheye lens - the basics of good photography
A big plus of this type of lens is that there are no problems with image focus. Due to the large area of contact with light, the picture is very clear and expressive. Center lines (horizontal and vertical) are not distorted.
The fisheye effect looks very nice when photographing the sky. In the forest, between houses, or just the sky dome itself, you can shoot with a circular type lens.
Wide aspect ratio allows you to take close-up photos of architectural objects. To make the picture harmonious, you need to try to respect its frame - connect horizontal or vertical lines with even building elements.
Funny portraits or just funny photos are obtained when shooting with a fisheye lens. The central zone is the least distorted, so this is where the main subjects should be placed. Four corner zones are areas of maximum distortion.
