Fotografi digital: Perbezaan antara semakan

Digital cameras can record movies but may be limited by storage capacity. A 1GB [[memory card]] will store approximately 1 hour's worth of video in an [[MPEG-4 Part 14|MP4]] format. Newer digital cameras, such as the [[Canon_Inc.|Canon]] PowerShot S1 IS, Canon PowerShot SD200/300 and the Pentax Optio MX/MX4 will capture continuous footage at a rate of 30 frames per second at a [[display resolution]] of 640x480 pixels (similar to a [[television]] screen). Some [[digital camera]]s can connect directly to a [[computer]] and store [[video]] on the computer's [[hard disk]] or [[DVD]] recorder.

 

 

The quality of a digital image is the sum of various factors many of which are similar to film cameras. [[Pixel]] count (typically listed in [[megapixel]]s) is only one of the major factors, though it is the most heavily marketed. Pixel count metrics were created by the marketing organizations of digital camera manufacturers because consumers can use it to easily compare camera capabilities. It is not, however, the major factor in evaluating a digital camera. The processing system inside the camera that turns the raw data into a color-balanced and pleasing photograph is the most critical, which is why some 4+ megapixel cameras perform better than higher-end cameras in a few cases.<!--These factors are just too many to list.-->

Throughout the history of photography, technological advances in optics, camera production, developing, and imaging have had an effect on the way people view images. Prior to the 1970s, most people in the United States used slide or chrome film and viewed the images with a slide projector. After that, people began to make prints from color negatives. The simultaneous increased use of the Internet and email, relatively cheap computers and digital cameras were seen in the early part of the 21st century, the dominant method of viewing still images has been on computers and, to a lesser extent, on cellular phones (although people still make and look at prints). These factors have led to a dramatic decrease in film and film camera sales and film processing and has had a dramatic effect on companies such as Fuji, Kodak, and Agfa. It is unknown whether film will continue to be purchased on the scale it has been for most of the 20th century, if it will disappear altogether, or if it will be something used by a dedicated few.
