The camera sets both an appropriate aperture and shutter speed for current lighting conditions. Auto Focus

The user can manually set the aperture while the camera selects a suitable shutter speed for correct exposure. Aperture Priority is useful for many photographic situations such as determining the depth of field for landscape photography. Barrel Distortion

This is a Binary Digit and can either be one of two states - 0 or 1. Bitmap

Taking multiple shots of the same scene with different exposure settings. Some cameras have an auto-bracketing option allowing 3 photographs to be taken at once with one image given more exposure than the standard image and one image given less for a darker image. Buffer

Binary unit composed of 8 bits. In computing, 1 kilobyte (1 kb) equals 1,024 bytes. 1 Megabyte (1 mb) equals 1,048,576 bytes and 1 Gigabyte (1 gb) equals 1,073,741,824 bytes.

Stands for Complementary Metal Oxide Semiconductor. With advances in technology the differences between CCD and CMOS sensors are now very minimal. CMOS sensors are a type of integrated circuit and convert light into electrons. See table above for CMOS & CCS sensor sizes. CompactFlash

The area within a photograph from the nearest subject to the furthest subject which is relatively sharp according to the photographer. Depth of field (DOF) can vary according to aperture selection, lens type and distance from the main subject. In general, larger apertures such as f2.8 will give less depth of field than smaller apertures such as f8 [..]

Many digital slr cameras now come with a facility to reduce or eliminate dust particles which may attach themselves to the CCD or image sensor when the user changes lenses leaving the inside of the digital slr camera exposed to outside dust and particles. Olympus pioneered dust reduction systems and modern Olympus digital slrs use a Supersonic Wave [..]

Dye sublimation printers are capable of producing high quality images and use a technique involving heating dyes composed of CMYO colors onto paper, plastic and other materials. The more commonly used CMYK colors are replaced by CMYO with the black dye being replaced by a clear coating which protects the print from moisture and fading from UV light [..]
