Focal distance (an equivalent for 35-mm) The focal distance is a distance which transits ray, refracting in a lens, to a point on a film where the image is printed. If the focal distance less, the more shooting corner will be, hence, more capacious frames turn out. At a row of models the focal distance is fixed and designated by one digit. Other models have ZOOM that allows increasing focal distance... 

Let’s get acquainted with terminology Thus, the image will be similar if we created it from three physically partitioned sensor controls (if colors RGB are used) as a result turns out. Therefore as a result the image transfers natural colors and passages in between. Except the described process, DSP is responsible for image resolution. Though the majority of digital cameras can be adjusted... 

Let’s get acquainted with terminology Some people can interpret incorrectly the term “bit depth of color”. For understanding of this term we will consider bases of digital color. All colors in the digital camera form by means of an intensity combination (or bit values) three principal colors – red, green and dark blue. These three principal colors also are called channels.... 

Direct downloading on FTP, web browsing and even more The model of Ricoh RDC i700 planned to fast release and it is capable to download automatically images on FTP protocol through the built in modem. For this purpose the camera is equipped similar PDA by the management interface with an electronic pen. Thus, the user can transfer both freeze frame images, and video clips, the text and a sound, using... 

Bases of a film photo In the normal film camera light is reflected from object or a scene and transits through the transparent glass or plastic lenses which focus it on a thin floppy slice of plastic (film). The film is covered by a photosensitive emulsion layer of haloid of silver. Light (photons) getting on a film leads to immediate chemical response which after chemical handling helps to show... 

If film cameras were finished and improved more than 160 years digital technologies of shooting are in infantile age: in vitro they are used for about 20 years, and in the consumer market numeral cameras have appeared only 7-8 years ago. Certainly, speed of development of technology for this period amazes, but a limit meanwhile is not reached, and numeral technologies of shooting will develop in directions...
