Leica camera (1950s) Hasselblad 500 C/M with Zeiss lens. A camera is an instrument used to capture and store images and videos, either digitally via an electronic image sensor, or chemically via a light-sensitive material such as photographic film. As a pivotal technology in the fields of photography and videography, cameras have played a ...
Light enters a dark box through a small hole and creates an inverted image on the wall opposite the hole. [2]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.
Olympus Air A01 lens camera, announced in 2014 and released in 2015, the lens camera is an open platform with an Android operating system and can detach into 2 parts (sensor module and lens), just like the Sony QX1, and all compatible Micro Four Thirds lenses can then be attached to the built-in lens mount of the camera's sensor module.
Focusing can be manual, by twisting the focus on the lens; or automatic, activated by pressing half-way on the shutter release or a dedicated auto-focus (AF) button. To take an image, the mirror swings upwards in the direction of the arrow, the focal-plane shutter opens, and the image is projected and captured on the image sensor. After these ...
While some cheaper point and shoot cameras may have a multi-image burst function which allows them to capture a number of frames within a second with a single shutter button press, most film and digital SLR cameras will continue to actuate the shutter for as long as the button is held down, until the memory card fills or the battery runs out ...
Once the camera is sensitive to the full-spectrum, external filters can be used to selectively filter portions of the UV, visible and infrared to achieve various effects. For example, a standard red #25a can be used to include red light and infrared light together, yielding particularly strong two-toned color images of a reddish nature except ...
Different kinds of camera lenses, including wide angle, telephoto and speciality. A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses (compound lens) used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically.
Some cameras have tens of modes. Many cameras do not document exactly what their many modes do; for full mastery of the camera, one must experiment with them. In general: Action or sports modes increase ISO and use a faster shutter speed to capture the action. Landscape modes use a small aperture to gain depth of field. Flash may be deactivated.
