Traditional Cameras/Digital Cameras
• Traditional cameras capture light onto photographic plate or photographic film. Video and digital cameras use an electronic image sensor, usually a charge coupled device (CCD) or a CMOS sensor to capture images which can be transferred or stored in a memory card or other storage inside the camera for later playback orprocessing.
• Cameras that capture many images in sequence are known as movie cameras or as ciné cameras in Europe; those designed for single images are still cameras.
• However these categories overlap as still cameras are often used to capture moving images in special effects work and many modern cameras can quickly switch between still and motion recording modes.
Digital Camera
• The first camera using digital electronics to capture and store images was developed by Kodak engineer Steven Sasson in 1975. He used a charge-coupled device provided by Fairchild Semiconductor, which provided only 0.01 megapixels to capture images. Sasson combined the CCD device with movie camera parts to create a digital camera that saved black and white images onto a cassette tape. The images were then read from the cassette and viewed on a TV monitor.Later, cassette tapes were replaced by flash memory.
Box Cameras
what is it?
A box camera is a simple type of camera, the most common form being a cardboard or plastic box with a lens in one end and film at the other. They were very popular in the late 19th and early 20th centuries.Because of the inability to adjust focus, the small lens aperture and the low sensitivity of the sensitive materials available, these cameras work best in brightly lit day-lit scenes when the subject is within the hyperfocal distance for the lens and of subjects that move little during the exposure.
A camera is an optical instrument for recording or capturing images, The images may be individual still photographs or sequences of images constituting videos or movies. The word camera comes from camera obscura, which means "dark chamber" and is the Latin name of the original device for projecting an image of external reality onto a flat surface.. The function of the camera is very similar to the function of the human eye. The first permanent photograph was made in 1826 by Joseph Nicéphore Niépce.
Who was Joseph Nicepohore Niepce?
He was an French inventor he was born the 5 of March of 1765 and he died the 5 of July of 1833.
Niépce was born in , Saône-et-Loire, where his father was a wealthy lawyer; this caused the whole family to flee the French Revolution. His older brother Claude (1763–1828) was also his collaborator.
He used a sliding wooden box camera made by Charles and Vincent Chevalier in Paris. Niépce had been experimenting with ways to fix the images of a camera obscura since 1816.
Functional description
• A camera works with the light of the visible spectrum or with other portions of the electromagnetic spectrum. A still camera is an optical device which creates a single image of an object or scene and records it on an electronic sensoror photographic film. All cameras use the same basic design: light enters an enclosed box through a converging lens/convex lens and an image is recorded on a light-sensitive medium. A shuttermechanism controls the length of time that light can enter the camera. Most photographic cameras have functions that allow a person to view the scene to be recorded, allow for a desired part of the scene to be in focus, and to control the exposure so that it is not too bright or too dim.
