The invention of the fisheye lens is originally used to study metorology, they needed a lense that would allow them to view the entire sky at once in order to get a better view of the formations overhead. Due to the interesting distortion the lens gives to photos it became popular fo use in general photography. The lens used for this is a wide angle lens that gives the photo a rounded or hemispherical distortion. The two most common types of fisheye lens are the circular fisheye lens and the full frame fisheye lens. Each of these lenses gives images a different look, however both follow the principle that the image will have a convex appearance. The mapping function describes the differences between both lenses. The circular lens was developed before the full frame lens, however the full frame lens has risen in popularity during the modern era of photography. Interesteningly, we can find fisheye concepts I many other places; some of which include in planetariums which use the idea to showcase the sky, peepholes on doors, and flight simulators. It is understandable why this concept can be useful in many different walks of life. The idea is to capture more surface area in less space. Personally, my new digital camera has a fisheye option and when I noticed it I became intrigued by the different ways it can be used to change the perspective of any picture.
