Viewer mode (full-screen view) A view mode in full-screen view, similar to the Viewer in the
Aperture main window. When full-screen view is set to Viewer mode, photos are presented
at high resolution over a solid-color background. Viewer mode is ideal for performing image
adjustments. See also Browser mode (full-screen view), full-screen view, Projects mode (full-screen

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 an 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,

watermark A visible graphic or text overlay applied to a photo to indicate that the photo is
protected by a copyright. Watermarks are applied to discourage the use of photos without the

waypoint A coordinate saved in a GPS track log representing a specific geographic location. In
Aperture, waypoints can be assigned to photos in Places view. See also GPS track log, Places view.
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 the 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. The White Balance
adjustment can also be used to neutralize color casts by identifying skin tones in the image. See
also color cast, color temperature, kelvin (K).
