AA - In the digicam world this refers to the most common power source, the AA-size battery.
AC Power - Running your digicam off the wall outlet power rather than by battery power. Usually means purchasing optional AC power adapter.
Add-On Lens - Some lenses have filter threads on the front edge that allow you to mount an auxiliary wideangle or telephoto lens in addition to the standard lens.
AE - Auto Exposure, a system for automatically setting the proper exposure according to the existing light conditions. There are three types of AE systems: · Programmed where the camera picks the best shutter speed and aperture automatically · Aperture Priority, the user chooses an aperture value and the shutter speed is automatically determined by lighting conditions · Shutter Priority, the user chooses a shutter speed and the aperture is automatically determined by lighting conditions AE Lock - The ability to hold the current exposure settings and allow you to point the camera elsewhere before capturing the image. This is usually accomplished by half-pressing the shutter button and keeping it at that position until you're ready to capture the image.
AF - Auto Focus. A system that automatically focuses the camera lens.
Aperture - The lens opening formed by the iris diaphragm inside the lens.
Aperture Priority AE - Exposure is calculated based on the aperture value chosen by the photographer. This allows for depth of field (DOF: Range of focus) control - large aperture = shallow DOF and a small aperture = deep DOF.
Artifact(ing) - Misinterpreted information from a JPEG or compressed image. Color faults or line faults that visibly impact the image negatively.
Aspherical Lens - A lens whose edges have been flattened so that it is not a perfect sphere, produces a superior image.
Automatic Exposure - The camera automatically adjusts the aperture or shutter speed or both for the proper exposure.
Autofocus - The camera lens focuses automatically, usually when the shutter release is half-pressed.
AVI - Movie clip in Windows' AVI format.
AWB - Automatic White Balance. A system for automatically setting the white balance in today's digital cameras. |

B&W - Term used to mean black and white Back Lit - The subject is heavily lit from behind which generally causes it to be underexposed unless you use critical spot metering.
Bit - The smallest unit of memory; a contraction from 'binary' and 'digit'. Binary digits are 0 and 1, also known as ons and offs.
Bit Depth - This refers to the color or gray scale of an individual pixel. A pixel with 8 bits per color gives a 24 bit image. (8 Bits X 3 colors is 24 bits.) 24 bit color resolution is 16.7 million colors.
Bitmap - The method of storing information that maps an image pixel, bit by bit. There are many bitmapped file formats, .bmp, .pcx, .pict, tiff, .tif, .gif, and so on. Most image files are bit mapped. This type of file gives you the 'jaggies', when examined closely you can see the line of pixels that create the edges.

CCD - Charged Coupled Device, a light sensitive chip used for image gathering. In their normal condition these are greyscale devices. To create color a color pattern is laid down on the sensor pixels, using a RGBG color mask (Red, Green, Blue, and Green) The extra Green is used to create contrast in the image. The CCD Pixels gather the color from the light and pass it to the shift register for storage. CCDs are analog sensors, the digitizing happens when the electrons are passed through the A to D converter. The A to D converter converts the analog signal to a digital file or signal. See also "CMOS" below.

CIFF - Camera Image File Format, an agreed method of digicam image storage used by many camera makers.
CMOS - Complementary Metal Oxide Semiconductor - Another imaging system used by digicams. It is not as popular as CCD but the future promises us even better digicams based on CMOS sensors due to the lower amount of power consumption versus the typical CCD device.
CMYK - Cyan, Magenta, Yellow, Black; These are the printer colors used to create color prints. Most Color Printers, Ink-Jet, Laser, Dye-Sublimation, Thermal, and Crayon printers use these as their printer colors. (This is one of the color management problems for computers. Converting RGB files to CMYK files cause's color shifts.) When used by a printer the CMYK is also known as a reflective color since it is printed on paper, or reflective films.

Color Depth - Digital images can approximate color realism, but how they do so is referred to as color depth, pixel-depth, or bit depth. Modern computer displays use 24-bit True Color. It's called this because it displays 16 million colors, about the same number as the human eye can discern.
CompactFlash - The most common type of digicam flash memory storage. It is removeable, small and available in sizes from 4MB up to 192MB. CF Type I the original 5mm high card CF Type II cards and devices that are 9mm high.

COM port - Your computer has serial communication ports which support the RS-232 standard of communication. This is the most common interface used to transfer data from a digicam to the computer.
Compression - A digital photograph creates an image file that is huge, a low-resolution 640x480 image has 307,200 pixels. If each pixel uses 24 bits (3 bytes) for true color, a single image takes up about a megabyte of storage space. To make image files smaller almost every digital camera uses some form of compression. See the "JPG" entry below.

DRAM - Dynamic Random Access Memory. A type of memory that is volatile - it is lost when the power is turned off.
DRAM Buffer - All digicams have a certain amount of fixed memory in them to facilitate image processing before the finished picture is stored to the flash memory card. Cameras that have a burst mode have much larger DRAM buffers, often as large as 32MB. This also makes them more expensive.
Dye Sub - Dye Sublimation is a printing process where the ink is thermally transferred to printing media. Usually expensive but it yields prints that rival real, wet-processed photographs.
Dynamic Range - A measurement of the accuracy of an image in color or gray level. More bits of dynamic range results in finer gradations being preserved. |

More and smaller pixels adds detail and sharpens edges. · Optical Resolution is an absolute number that the camera's image sensor can physically record. · Interpolated Resolution adds pixels to the image using complex software alogrythms to determine what color they should be. It is important to note that interpolation doesn't add any new information to the image - it just makes it bigger! Camera makers often specify the resolution as: QVGA (320 x 240), VGA (640 x 480), SVGA (800 x 600), XGA (1024 x 768) or UXGA (1600 x 1200)
