Apple Aperture - Manual (Page 451)

Glossary 451
vault A designated storage space that contains an exact copy of the Aperture Library
(from the last time you backed up), usually saved on an external FireWire drive. See also
FireWire , Library .
version The file containing all the metadata and adjustment information applied to an
image. In Aperture, only versions are changed. The master image files are never
touched. See also
master file .
Viewer An area in Aperture that displays the images currently selected in the Browser.
You can use the Viewer to perform adjustments on images as well as compare them
with each other. See also
Browser .
viewfinder The part of the camera designed to preview the area of the scene that will
be captured by the digital image sensor. See also
camera , digital image sensor .
vignetting Darkening, also known as fall-off, at the corners of the image as a result of
too many filters attached to the lens, a large lens hood, or poor lens design. See also
filters , lens .
watermark A visible graphic or text overlay applied to an image to indicate that the
image is protected by a copyright. Watermarks are used to discourage the use of your
images without your explicit permission.
white balance An adjustment that changes the color temperature and tint of a digital
image. The goal of adjusting an image’s white balance is to neutralize color casts in an
image. For example, if the white in an image is too yellow because of incandescent
lighting, white balancing adds enough blue to make the white appear neutral. See also
color cast , color temperature , kelvin (K) .
white point The color temperature of a display, measured in kelvins. The higher the
white point, the bluer the white is; the lower the white point, the redder the white. The
native white point for a Macintosh computer is D50 (5000 kelvins); for a Windows PC, 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 film plane or digital image sensor. See
also
digital image sensor , lens .
workspace The arrangement of the Browser, Viewer, Projects panel, and inspectors. In
Aperture, there are multiple workspaces. See also
Browser , Viewer .
working space The color space in which you edit a file. Working spaces are based
either on color space profiles such as Apple RGB or on device profiles.
zoom lens A lens that has the mechanical capacity to change its focal length; also
known as an optical zoom lens. See also
