- waterproof and weatherproof cameras
- Some compact cameras are waterproof and you can use them to take pictures underwater in the shallows. Weatherproof cameras are fitted with rubber seals around the most important parts so you can use them in the rain but you cannot use them underwater. If you are scuba diving you will need a proper underwater camera.
- Web Press
- An offset press that uses a continuous roll of paper rather than individual sheets (Sheet-fed). Web Offset is of lower quality then sheet-fed printing but is common where the press runs involve very large numbers of copies. Because the paper is a continuous roll and is moving very fast it is more difficult to achieve accurate registration.
- white balance
- Digital cameras and camcorders have a white balance control to prevent unwanted colour casts. Unlike photographic colour film which is badly affected by artificial light digital cameras can record colour-corrected pixels without needing special filters.
- whiteout
- In digital photographs excessive light can cause whiteout. Unlike film where detail can be coaxed out of overexposed negatives with careful printing white pixels cannot be modified to produce hidden detail.
- Whitepoint
- The whitepoint of a color display monitor is the color temperature of the monitor. The color temperature is stated in degrees Kelvin (K) and represents how warm or cool the white of the monitor is. Uncalibrated monitors generally have a very blue white (often as high as 9300K) The printing industry uses a standard called D5000 which is 5000K and closely resembles Daylight.
- wide angle lens
- Wide angle lenses are ideal when you are shooting in confined spaces like indoors. They have the opposite effect of telephoto lenses and 'push' your subjects away from you. If you use a wide angle lens to take pictures of people their faces can appear distorted.
- Wintel
- A computer running Windows on an Intel processor chip.... your basic PC clone.
