![]() ![]() In 1779, Horace Bénédict de Saussure published his downward-facing fisheye view of the Alps: "All the objects are drawn in perspective from the centre". Panoramas with fisheye distortion predate photography and the fisheye lens. In everyday life, they are perhaps most commonly encountered as peephole door viewers to give a wide field of view. They are also used for scientific photography, such as recordings of aurora and meteors, and to study plant canopy geometry, and to calculate near-ground solar radiation. For digital cameras using smaller imagers such as 1⁄ 4″ and 1⁄ 3″ format CCD or CMOS sensors, the focal length of "miniature" fisheye lenses can be as short as 1–2 mm.įisheye lenses also have other applications, such as re-projecting images originally filmed through a fisheye lens, or created via computer-generated graphics, onto hemispherical screens. For the popular 35 mm film format, typical focal lengths of fisheye lenses are 8–10 mm for circular images, and 12–18 mm for diagonal images filling the entire frame. Mass-produced fisheye lenses for photography first appeared in the early 1960s and are generally used for their unique, distorted appearance. Their focal lengths depend on the film format they are designed for. The angle of view of a fisheye lens is usually between 100 and 180 degrees, although lenses covering up to 280 degrees exist (see below). ![]() : 145 Their first practical use was in the 1920s for use in meteorology to study cloud formation giving them the name "whole-sky lenses". Wood based on how a fish would see an ultrawide hemispherical view from beneath the water (a phenomenon known as Snell's window). ![]() The term fisheye was coined in 1906 by American physicist and inventor Robert W. Chromatic aberration can clearly be seen toward the outer edges. For example, in scenery and landscape photography, it is often used to express the texture of objects in strong reflections, highlight the scenery behind the glass, darken the sky, and express the blue sky and white clouds.Ħ.The starlight lens can turn the light source in the picture into a 4-line star point, creating a romantic and childlike mood and increasing the artistic effect of the photo.ħ.A radiographic lens allows you to shoot a visual effect similar to radioactivity, which allows you to easily take photos with shocking visual impact.ġ.Please allow slight size deviations due to manual measurement,measuring methods and tools.Ģ.The picture may not reflect the actual color of the item because of different photographing light and display monitor.Thanks for your understanding.Circular fisheye photograph of Oude Kerk Amsterdam. The long depth of field can show a considerable range of clarity the shooting range is larger than before, and it has good results for shooting landscapes, urban architecture and large-scale photography, gatherings and family photos.Ģ.The macro lens is 15 times the macro, the effective focusing distance is 2-3CM, shooting small objects, fully showing the details discovering the beauty of details and feeling the micro world.ģ.The teleconverter lens is a 2x teleconverter, which can increase the optical focal length of the mobile phone and is suitable for portrait shooting.Ĥ.The flow lens can make the static object shoot the dynamic effect of the movement, without the help of any image software, you can also take wonderful photos.ĥ.Polarized lenses are commonly used in color and black-and-white photography to eliminate or weaken the strong reflection of non-metallic surfaces, thereby eliminating or reducing light spots.
