A camera obscura (pl. camerae obscurae or camera obscuras; from Latin camera obscūra 'dark chamber') [1] is the natural phenomenon in which the rays of light passing through a small hole into a dark space form an image where they strike a surface, resulting in an inverted (upside down) and reversed (left to right) projection of the view outside.
A pinhole camera is a simple camera without a lens but with a tiny aperture (the so-called pinhole)—effectively a light-proof box with a small hole in one side. Light from a scene passes through the aperture and projects an inverted image on the opposite side of the box, which is known as the camera obscura effect.
Archaeo-optics, or archaeological optics, is the study of the experience and ritual use of light by ancient peoples.Archaeological optics is a branch of sensory archaeology, which explores human perceptions of the physical environment in the remote past, and is a sibling of archaeoastronomy, which deals with ancient observations of celestial bodies, and archaeological acoustics, which deals ...
The camera obscura was well known for centuries and documented by Ibn al-Haitham in his Book of Optics of 1011–1021. In 13th-century England Roger Bacon described the use of a camera obscura for the safe observation of solar eclipses, exactly because the viewer looks at the projected image and not the sun itself.
The fundamental technology of most photography, whether digital or analog, is the camera obscura effect and its ability to transform of a three dimensional scene into a two dimensional image. At its most basic, a camera obscura consists of a darkened box, with a very small hole in one side, which projects an image from the outside world onto ...
In the 16th century some experimental optical entertainment - for instance camera obscura demonstrations - were part of the cabinets of curiosities that emerged at royal courts. Since the 17th century, optical tabletop instruments such as the compound microscope and telescope were used for parlour entertainment or salon presentations in richer ...
An 18th-century artist utilizing a camera obscura for image tracing. The camera obscura (from the Latin for 'dark room') is a natural optical phenomenon and precursor of the photographic camera. It projects an inverted image (flipped left to right and upside down) of a scene from the other side of a screen or wall through a small aperture onto ...
The history of the single-lens reflex camera (SLR) begins with the use of a reflex mirror in a camera obscura described in 1676, but it took a long time for the design to succeed for photographic cameras. The first patent was granted in 1861, and the first cameras were produced in 1884, but while elegantly simple in concept, they were very ...
