2. Fisheye lens - Wikipedia

   en.wikipedia.org/wiki/Fisheye_lens

   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 ...

3. Hugin (software) - Wikipedia

   en.wikipedia.org/wiki/Hugin_(software)

   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 ...

4. Angle of view (photography) - Wikipedia

   en.wikipedia.org/wiki/Angle_of_view_(photography)

   (In the case of a lens with distortion, e.g., a fisheye lens, a longer lens with distortion can have a wider angle of view than a shorter lens with low distortion) [3] Angle of view may be measured horizontally (from the left to right edge of the frame), vertically (from the top to bottom of the frame), or diagonally (from one corner of the ...

5. Nikkor 13mm f/5.6 - Wikipedia

   en.wikipedia.org/wiki/Nikkor_13mm_f/5.6

   Retail info. MSRP. 8,229.00 (1979 price) USD. The Nikkor 13mm f/5.6 is an ultra-wide angle rectilinear lens which was manufactured by Nikon for use on Nikon F mount cameras until 1998. [1] It has been dubbed 'The Holy Grail', for its low-distortion ultra-wide capabilities. The lens was produced by Nikon only upon receipt of an order, thus ...

6. Rectilinear lens - Wikipedia

   en.wikipedia.org/wiki/Rectilinear_lens

   [1]: 59 As of 2020, the Laowa 9mm f/5.6 lens is the world's widest rectilinear lens for full frame cameras. [2] The vast majority of video and still cameras use lenses that produce nearly rectilinear images. A popular alternative type of lens is a fisheye lens which produces a distinctly curvilinear, wide-angled result.

7. Panoramic photography - Wikipedia

   en.wikipedia.org/wiki/Panoramic_photography

   While there is no formal division between "wide-angle" and "panoramic" photography, "wide-angle" normally refers to a type of lens, but using this lens type does not necessarily make an image a panorama. An image made with an ultra wide-angle fisheye lens covering the normal film frame of 1:1.33 is not automatically considered to be a panorama.

8. Hemispherical photography - Wikipedia

   en.wikipedia.org/wiki/Hemispherical_photography

   Hemispherical photograph used to study microclimate of winter roosting habitat at the Monarch Butterfly Biosphere Reserve, Mexico.. Hemispherical photography, also known as canopy photography, is a technique to estimate solar radiation and characterize plant canopy geometry using photographs taken looking upward through an extreme wide-angle lens or a fisheye lens (Rich 1990).

9. Luneburg lens - Wikipedia

   en.wikipedia.org/wiki/Luneburg_lens

   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 ...
