Hello all,
Search for Robert Hill, at the Cambridge University Library (sorry, link
missing)
quoting :
*
Hill had a long-standing interest in meteorology. In the early 1920s he began to
work on a camera equipped with a 'fish-eye'
lens which could photograph through 180° and thus take
photographs of the whole sky at one instant. Using a pair of fish-eye
cameras one could calculate the height of clouds. In addition
to photographing the whole sky Hill's camera it was also possible
to photograph the whole of the inside of a building, town
square etc.
The first form of lens was described by Hill in 'A lens for
whole sky photographs', Quarterly Journal of the Royal Meteorological
Society 50 (1924), 227-232 (Bibliog. no. 7) where it aroused
considerable interest. Hill approached R. & J. Beck Ltd and had a
number of experimental lens designed before camera was marketed
by them.
The camera went under a number of names; the 'Robin Hill
camera', 'Hill's cloud camera', 'Whole-sky camera' etc. It is probably
best known, however, as the fish-eye camera.
