As Seen Through a Telescope (AKA: The Professor and His Field Glass) is a 1900 British short silent comedy film, directed by George Albert Smith, featuring an elderly gentleman getting a glimpse of a woman's ankle through a telescope.
The three-shot comedy, according to Michael Brooke of BFI Screenonline, "uses a similar technique to that which G.A.
Smith pioneered in Grandma's Reading Glass (1900)," and, although "the editing is unsophisticated, the film does at least show a very early example of how to make use of point-of-view close-ups in the context of a coherent narrative (which is this film's main advance on Grandma's Reading Glass)."
"Smith's experiments with editing," Brooke concludes, "were ahead of most contemporary film-makers, and in retrospect it can clearly be seen that he was laying the foundations of film grammar as we now understand it.
"[1][2] The film was shot in Furze Hill, Hove, England outside the entrance to St. Ann's Well Gardens, where Smith had his studio.
