English - Turkish

(isim) karanlık oda
English - English
{n} a philosophical apparatus and optical machine used to exhibit images by
A darkened chamber in which the image of an outside object is projected and focused onto a surface
(taken from Latin and means 'dark room' ) Invented in the sixteenth century, the camera obscura is made out of an arrangement of lenses and mirrors in a box (or room) that is darkened When looking through the lens of a 'camera obscura', the view presented is actually reflected through the mirrors onto the paper or cloth and allows the artist to draw by tracing the outline This forerunner of the modern camera was a tool for recording an optically accurate image, often of topographical detail (Canaletto used one to study his vedute prior to painting)
Literally means darkroom A box first used by the Greek philosopher Aristotle (384 -322 BC) to concentrate light onto the back of a dark box through a small opening in the front
Latin for “dark chamber”: a darkened room with a small opening through which rays of light could enter and form an image of the scene outside Eventually a lens was added at the opening to improve the image, and the room shrank to a small, portable box
A device used by early artists (centuries before Christ) to display a scene on the wall of an otherwise-darkened room so that it could be more-easily copied In a manner similar to the pinhole camera, a small hole placed in an opposite wall permitted light to enter the room (the "camera"), and the scene outside became transmitted inside, and was shown inverted on the rear wall or sometimes on a screen The camera obscura is the origin of the modern camera
The first practical instrument to resemble a modern camera was the camera obscura (literally, an 'obscure' or 'darkened chamber'), a contraption which allowed an image to be transferred by means of a lens fitted over the hole to a sheet of paper suspended on the other side of the chamber, where the image could be then be traced with some precision
An apparatus in which the images of external objects, formed by a convex lens or a concave mirror, are thrown on a paper or other white surface placed in the focus of the lens or mirror within a darkened chamber, or box, so that the outlines may be traced
From the Latin "dark chamber " A camera obscura took on several forms, it could be darkened box or room with a small opening on one side Light rays enter through the small opening and form an image of the scene outside In its box form it is sometimes called a pinhole camera
Ancestor of the photographic camera The Latin name means "dark chamber," and the earliest versions, dating to antiquity, consisted of small darkened rooms with light admitted through a single tiny hole The result was that an inverted image of the outside scene was cast on the opposite wall, which was usually whitened For centuries the technique was used for viewing eclipses of the Sun without endangering the eyes and, by the 16th century, as an aid to drawing; the subject was posed outside and the image reflected on a piece of drawing paper for the artist to trace Portable versions were built, followed by smaller and even pocket models; the interior of the box was painted black and the image reflected by an angled mirror so that it could be viewed right side up The introduction of a light-sensitive plate by J -N Niepce created photography
An apparatus in which the image of an external object or objects is, by means of lenses, thrown upon a sensitized plate or surface placed at the back of an extensible darkened box or chamber variously modified; commonly called simply the camera
a darkened enclosure in which images of outside objects are projected through a small aperture or lens onto a facing surface
{i} small chamber in which outside images are projected onto a surface; dark room
A darkened boxlike device in which images of external objects, received through an aperture, are exhibited in their natural colors on a surface arranged to receive them [7]
the "Dark Chamber" or box that was used as a type of camera in the very early days
A darkened enclosure where light passes through a lens pinhole and an upside-down image is seen on the opposite surface
An ancestor of the modern camera in which a tiny pinhole, acting as a lens, projects an image on a screen, the wall of a room, or the ground glass wall of a box; used by artists in the 17th and 18th centuries, and early 19th century as an aid in drawing from nature Literally, "dark room "
An optical contrivance for projecting the image of an object or scene on a surface, from which it is traced and thus is more accurately reproduced than by being drawn freehand
