Some [[fisheye lens]]es use a stereographic projection to capture a wide-angle view.<ref>[http://www.syopt.co.kr/eng/product/8mm.asp Samyang 8 mm {{f/}}3.5 Fisheye CS] {{Webarchive|url=https://web.archive.org/web/20110629031236/http://www.syopt.co.kr/eng/product/8mm.asp |date=2011-06-29 }}</ref> Compared to more traditional fisheye lenses which use an equal-area projection, areas close to the edge retain their shape, and straight lines are less curved. However, stereographic fisheye lenses are typically more expensive to manufacture.<ref>{{cite web|url=http://www.lenstip.com/160.1-Lens_review-Samyang_8_mm_f_3.5_Aspherical_IF_MC_Fish-eye-Introduction.html|title=Samyang 8 mm f/3.5 Aspherical IF MC Fish-eye|publisher=lenstip.com|access-date=2011-07-07}}</ref>  Image remapping software, such as [[Panotools]], allows the automatic remapping of photos from an equal-area fisheye to a stereographic projection.

The stereographic projection has been used to map spherical [[panorama]]s, starting with [[Horace Bénédict de Saussure]]'s in 1779. This results in effects known as a ''little planet'' (when the center of projection is the [[nadir]]) and a ''tube'' (when the center of projection is the [[zenith]]).<ref name="German2007">German ''et al.''

The popularity of using stereographic projections to map panoramas over other azimuthal projections is attributed to the shape preservation that results from the conformality of the projection.<ref name="German2007"/>
