What is Fish eye vision?

Fisheye vision is a type of wide-angle photography that uses a special lens to capture a wide field of view. Fisheye lenses have a short focal length, which allows them to capture a wider image than a standard lens. This can create a distorted, exaggerated image, but it can also be used to create unique and interesting photos.

Fisheye lenses are often used in extreme sports photography, action sports photography, and underwater photography. They can also be used for creative photography, such as landscape photography and street photography.

How does fisheye vision work?

Fisheye lenses use a convex lens that curves in towards the center. This causes the light rays that enter the lens to be bent (refracted) towards the center of the image. This bending of the light rays creates the characteristic distorted image of a fisheye photo.

The amount of distortion in a fisheye photo depends on the focal length of the lens. Lenses with a shorter focal length produce more distortion than lenses with a longer focal length.

Types of fisheye lenses

There are two main types of fisheye lenses: full-frame and circular.

- Full-frame fisheye lenses capture the entire image circle of the camera's sensor. This produces a circular image with a black border around the edges.

- Circular fisheye lenses only capture a portion of the image circle of the camera's sensor. This produces a circular image without a black border.

Circular fisheye lenses are more popular for still photography, while full-frame fisheye lenses are more commonly used for video.

Uses of fisheye vision

Fisheye lenses are used in a wide variety of applications, including:

* Extreme sports photography: Fisheye lenses are often used to capture the wide-angle action of extreme sports, such as skateboarding, snowboarding, and surfing.

* Action sports photography: Fisheye lenses are also used to capture the fast-paced action of action sports, such as motocross, BMX, and mountain biking.

* Underwater photography: Fisheye lenses are ideal for capturing the underwater world, as they can capture a wide field of view and produce a unique, distorted perspective.

* Creative photography: Fisheye lenses can be used to create unique and interesting photos for creative photography, such as landscape photography and street photography.

Fisheye lenses can be a great tool for photographers who want to capture a wide-angle view or create unique and distorted images.
