1708, "vaulted building; arched roof or ceiling," from Latin camera "a vault, vaulted room" (source also of Italian camera, Spanish camara, French chambre), from Greek kamara "vaulted chamber, anything with an arched cover," which is of uncertain origin. A doublet of chamber. Old Church Slavonic komora, Lithuanian kamara, Old Irish camra all are borrowings from Latin.
The word also was used from early 18c. as a short form of Modern Latin camera obscura "dark chamber" (a black box with a lens that could project images of external objects), contrasted with camera lucida (c. 1750, Latin for "light chamber"), which uses prisms to produce on paper beneath the instrument an image which can be traced of a distant object.
This sense was expanded to become the word for "picture-taking device used by photographers" (a modification of the camera obscura) when modern photography began c. 1840. The word was extended to television filming devices from 1928. Camera-shy is attested from 1890. Camera-man is from 1908.
Old English lond, land, "ground, soil," also "definite portion of the earth's surface, home region of a person or a people, territory marked by political boundaries," from Proto-Germanic *landja- (source also of Old Norse, Old Frisian Dutch, Gothic land, German Land), perhaps from PIE *lendh- (2) "land, open land, heath" (source also of Old Irish land, Middle Welsh llan "an open space," Welsh llan "enclosure, church," Breton lann "heath," source of French lande; Old Church Slavonic ledina "waste land, heath," Czech lada "fallow land"). But Boutkan finds no IE etymology and suspects a substratum word in Germanic,
Etymological evidence and Gothic use indicates the original Germanic sense was "a definite portion of the earth's surface owned by an individual or home of a nation." The meaning was early extended to "solid surface of the earth," a sense which once had belonged to the ancestor of Modern English earth (n.). Original senses of land in English now tend to go with country. To take the lay of the land is a nautical expression. In the American English exclamation land's sakes (1846) land is a euphemism for Lord.
