The camera obscuraEarly photo folk ( homonikonicus blanko pict-erectus ) had no way topreserve images produced bycamera obscuras apart frommanually tracing the images.Some early obscuras - wereroom sized & known to existin the Arab world.Hence the word Cameracoming from the Arab ....QamaraCamera Obscura means......The Darkened Chamber 5. Late Iberian- Homo nikonicus erectus... pretends he has a qamara 6. ...examples of camera obscura 7. Why is the image projected upsidedown camera obscura or pin hole?Light travels in a straight line, which means rays from above the pinhole will pass through itand hit the bottom of the wall opposite. Raysfrom below the pinhole will hit the top of theback wall; hence, forming the upside downimage. 8. Now you get to make your ownCamera Obscura Get a Pringles tube & remove opened end. Insert a rolled piece of black paper inside thetube, to make the inside dark. Poke a pinhole in one end about 1.5mm diameter& leave in place. Remove other end & place a piece of tracing orgreaseproof paper neatly on the open end secure with cellotape. There you have it go point it at somethingbright 9.

Bit about photographic plates Plates preceded photographic film as atarget medium in photography. A light-sensitive emulsion of silver saltswas applied to a glass plate. This form of photographic materiallargely faded from the consumer marketin the early years of the 20th century, asmore convenient and less fragile films Negative Platewere introduced. Photographic plates were still in use bysome photography businesses until the1970s and were in wide use by theprofessional astronomical community aslate as the 1990s.
