Digital Photography Definitions (V to Z)


Below are definitions to many terms which come up when reading digital camera reviews and discussions of digital photography in general.

.........Term........ Definition
VR
(Nikon)
Vibration Reduction. This is Nikon's nomenclature for a lens which has the ability to correct for "Camera Shake". The latest Nikon lenses having the VR designation offers the equivalent of using a shutter speed 3-stops faster, because internal sensors detect motion on the X and Y, or vertical (V) and horizontal (H) axes. For example, shooting in low-light under 1/60sec can be done quite easily.
White Balance Making your photos appear as close to "white" and neutral. WB is the process of adjusting the color based on a particular lighting situation, so that the colorcast of the scene, is accurately represented in the image taken from the camera. For example, tungsten/incandescent lighting requires a setting of around 3000K. Typical lighting in homes has a warm, amber colorcast to it due to the commonality of tungsten lightbulbs. In order to neutralize this color, and make it more "white", a lower temperature setting is used. If you had an image that appeared blueish or "cold", you would want to "warm it up", by selecting a higher temp to compensate.
xD eXtreme digital. Olympus Optical, FujiFilm, and Toshiba created this successor to the SmartMedia format. xD is measured at 25mm (W) x 20mm (H), and 1.7mm thick. xD became available in late 2002. As expected, xD is used in almost all Olympus cameras, and several Fuji cameras. Unfortunately, xD is taking the same slow inevitable death that SM did only a few years ago. The major reason? Cross-Platform compatability. xD was engineered for mainly cameras, and this was a big mistake. SD will most likely be the dominant micro-media choice. Currently, SD and CF cards cost less by at least 50% of xD media. If you're a company that wants a media format to take hold, be darn sure your media is not so proprietary, that others can't make it or use it in their digital devices. for more information on xD cards, please visit FujiFilm's Website.
