What is Fishye's camera?

Fishye is a camera that uses an extremely wide -angle lens to capture the tracking range of about 180 degrees. This type of camera is called "fish eye" because it is closer to seeing a fish convex eye. The lens creates curves of a large area and at the same time distorts the perspective and angles of objects in the figure.

There are two types of fishing cameras and produce different angles, different types of distortion and different shapes of photos. The full frame lenses capture an image that is usually 180 degrees from the corner to the corner, while the vertical and horizontal angles are smaller. These images fill in a rectangular film frame. Circular lenses generally capture 180 degrees on horizontal, vertical and diagonal angles. Pictures captured by round lenses are round or oval inside the film frame and the frame around the picture is black.

The length of the fishing lens lens depends on the camera format. Using 35 mm Film format and circular image will usually have a focal length of 8-10mm, while a full frame image will have a focal length of 15-16 mm. Newer lenses were created with a focal length in the range of 4.6-6 mm. Digital cameras with disposable lens (SLR) in 1/4 inch format or 1/3 inch may have a focal length of 1-2 mm.

The

Fisheye camera was first developed for scientific use, recording astronomical features full of sky, and taking pictures of the canopy for analysis. One of the advantages of an ultra -angle lens is the ability to photograph a great view from the limited space. For this reason, the Fishye miniature lenses are valuable in safety and commercial cameras as they can record activity in a wide area from a single convenient place. IMAX also uses the Fisheye camera to capture panoramic films and screening of movies on a screen -like screen.

Photographers also use distortion and the wide -angle advantage of these lenses createsRate interesting and unusual pictures. The landscape acquired by the Fisheye camera shows a distinctive curve of the country. Subjects near the camera will have large, distorted properties, while the focal length causes that the subjects at a distance look unusually small. On the camera with a view of 180-185 degrees, two photos taken from exactly the opposite directions can be digitally combined to create a complete 360-degree image. Because of these interesting image creation options, the Fishye camera has become a favorite gadget.
