white balance
An adjustment that changes the color temperature of a digital image. The goal is to reproduce white as true white. For example, if the white in an image is too yellow due to incandescent lighting, white balancing adds enough blue to make the white appear neutral. See also color temperature, kelvin (K).
white point
The color temperature of a display, measured in kelvins. The higher the white point, the bluer the white; the lower the white point, the redder. The native white point for a Mac is D50 (5000 kelvins); for Windows, it is D65 (6500 kelvins). See also color temperature, kelvin (K).
wide-angle lens
A lens with a short focal length that takes in a wide view. The focal length of a wide-angle lens is smaller than the image frame. See also lens.
working space
The color space in which a file is edited. It can be different from the original color space of the file, which is called the document color space. Working spaces are based either on color-space profiles such as Apple RGB or on device profiles.
workspace
The arrangement of the Browser, Viewer, Adjustments Inspector, Metadata Inspector, Projects panel, and other interface elements. There are multiple workspaces in Aperture.
