disk, a hard drive or Random-Access Memory (RAM), and an integrated circuit (IC) card or chip. floppy disk capable of recording 50 or 25 images. The number of images that can be recorded on a floppy disk depends on whether the image is recorded in the field" or "frame" mode. disk. The field mode provides poorer resolution because there are less pixels per picture. The FRAME MODE uses two tracks per image and allows 25 images to be stored on one floppy disk. The frame mode provides higher quality because more pixels per image are recorded. and colors that are created electronically by the intensity and the color of light striking an image sensor within the camera. This analog signal is the same type of signal used to record most motion-video images. It is also the same type of signal used in conventional television. Many still-video cameras have a playback capability and may be connected directly to a television monitor memory per image. Most still-video cameras have a limited resolution of approximately 380,000 pixels. chips that are used as the image pickup device and the high-band format to improve resolution. format and configuration of a still-video floppy disk is digital. By using the appropriate hardware and software, you must convert an image captured on a still-video camera from analog to digital format before it can be modified or printed in a digital-imaging system. uses the binary system of "0s and 1s." The combination of these digits represents densities and colors created pixels per image, but it also requires much more memory per image. Digital cameras use an IC card or permanently into the camera and must be downloaded to another storage device. This storage device is an internal or external hard drive. This hard drive is similar to the hard drive found in personal computers. Kodak's images. back to capture high-resolution color or black-and-white images. The Nikon body operates similar to a camera with conventional film. The major compared to the DCS back is that the image area of the DCS is only one half of the size of a 35mm-film frame. This change in image area affects the effective focal length. For example, a conventional 35mm lens becomes a 70mm lens with the DCS. The Nikon F-3 functions, aperture settings, shutter speeds, and light metering operate the same as with film. Three major components that make up the Kodak DCS are as follows: an electronic back, a camera winder, and a digital storage unit. means the CCD is capable of recording about 1.3 million pixels. The color back equates to film speeds of 200,400, and 800. The monochrome back equates to film speeds of 400, 800, 1600, and 3200. megabyte (Mb) buffer that can store six images in one burst. Thus it is possible to shoot faster than the images are stored. The 200Mb hard drive can store 158 uncompressed images or about 600 compressed images. The DSU also has a key pad for system control and a 4-inch monochrome monitor so you can view the images immediately. Advanced Photography Course |
