data. See also camera, FireWire, tethered shooting.

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 masters are never touched. See

also master.

Vibrancy parameter An Enhance adjustment parameter in Aperture used to add

saturation in an image in a nonlinear manner. Saturated colors are left alone while

saturation is added to all other colors. However, skin tones are not modified. See also

adjustment, desaturate, Enhance adjustment, saturation.

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.

also Browser, Browser & Viewer view, Browser Only view, Full Screen view, Viewer.

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.

Vignette adjustment An adjustment in Aperture designed to add a vignette effect to

an image. See also Devignette adjustment, vignetting.

vignetting a. Darkening, also known as falloff, 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. b. The

process of applying a vignette to an image for artistic effect. See also Devignette

adjustment, filters, lens, Vignette adjustment.

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

images without the copyright holder’s explicit permission.

White Balance adjustment An adjustment in Aperture 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, k

elvin (K).
