A fisheye lens is an ultra wide-angle lens that produces strong visual distortion intended to create a wide panoramic or hemispherical image. [4][5]: 145 Fisheye lenses achieve extremely wide angles of view, well beyond any rectilinear lens. Instead of producing images with straight lines of perspective (rectilinear images), fisheye lenses use ...
A panomorph lens is a particular type of wide-angle lens specifically designed to improve optical performances in predefined zones of interest, or across the whole image, compared to traditional fisheye lenses. [1] [predatory publisher] Some examples of improved optical parameters include the number of pixels, the MTF or the relative illumination.
Hugin (/ ˈhʊɡɪn /) is a cross-platform open source panorama photo stitching and HDR merging program developed by Pablo d'Angelo and others. It is a GUI front-end for Helmut Dersch's Panorama Tools and Andrew Mihal's Enblend and Enfuse. Stitching is accomplished by using several overlapping photos taken from the same location, and using ...
Panoramic photography is a technique of photography, using specialized equipment or software, that captures images with horizontally elongated fields of view. It is sometimes known as wide format photography. The term has also been applied to a photograph that is cropped to a relatively wide aspect ratio, like the familiar letterbox format in ...
DxO ViewPoint is image geometry and lens defect correction software developed by DxO. It is designed to automatically straighten distorted perspectives caused by the lens used and the position of the photographer. The software claims to be able to make precise corrections to lens flaws through its use of DxO's database of calibrations (called ...
ptgui.com. PTGui is a panorama photo stitching program for Windows and macOS developed by New House Internet Services BV. PTGui was created as a GUI frontend to Helmut Dersch 's Panorama Tools. It features its own stitching and blending engine [2] along with compatibility to Panorama Tools.
A Luneburg lens (original German Lüneburg lens) is a spherically symmetric gradient-index lens. A typical Luneburg lens's refractive index n decreases radially from the center to the outer surface. They can be made for use with electromagnetic radiation from visible light to radio waves. For certain index profiles, the lens will form perfect ...
The smc Pentax-F 17–28mm Fish-eye f / 3.5–4.5 is the first fisheye zoom lens, manufactured by Pentax for single-lens reflex cameras (SLRs) with a K lens mount.At its widest setting of 17mm, it affords a 180° diagonal angle of view images for all K-mount full-frame SLR cameras; at 28mm, the diagonal angle of view is reduced to 90° on the diagonal.
