Glossary 513
HUD Short for heads-up display. In Aperture, HUDs are floating windows that allow you to work
on your image. You can open and then move a HUD wherever you wish, based on your display
setup. See also full-screen view.
hue An attribute of color perception; also known as color phase. For example, red and blue are
different hues. See also Color adjustment.
ICC profile Created as a result of device characterization, the ICC profile contains the data
about the device’s exact gamut. See also device characterization, gamut, International Color
Consortium (ICC).
image An artifact that reproduces the likeness of some subject, usually a physical object or
person, also known as a picture. See also photograph, photo selection, picture, subject.
importing The process of bringing digital image files, audio files, and video files of various types
into a project in Aperture. Imported files can be created in another application, downloaded
from a camera or card reader, or brought in from another Aperture project. See also project.
inkjet printer A type of printer that creates images by spraying little ink droplets onto the paper.
See also dye sublimation, photo printer, print, RA-4.
Inspector HUD A floating window that contains the Library, Metadata, and Adjustments panes.
See also Inspector pane.
Inspector pane An element of the Aperture main window that contains the Library, Info, and
Adjustments inspectors. See also Inspector HUD.
Intensify Contrast Quick Brush A type of Quick Brush adjustment that corrects the shadow
areas of the image that appear washed out by intensifying the contrast between pure black and
50 percent gray in the area of the image the adjustment is brushed on. The Intensify Contrast
Quick Brush adjustment is equivalent to applying an Overlay blend. See also adjustment, Brush
HUD, contrast, Polarize Quick Brush, Quick Brushes, shadows.
International Color Consortium (ICC) An organization established to create the color
management standard known as the ICC profile. ICC profiles are universally accepted by hardware
and software vendors because they’re based on an open standard. See also ICC profile.
IPTC Short for International Press Telecommunications Council. IPTC metadata is used
by photographers and media organizations to embed keywords (words describing the
characteristics of the image, including the photographer’s name) in the image files themselves.
Large publishers typically use image management systems to quickly identify photos based on
the IPTC information embedded in the image file. See also EXIF, metadata.
IPTC Core A defined set of metadata fields, primarily used by photographers and news media,
built on Adobe’s XMP technology. See also IPTC, metadata, XMP sidecar file.
iris See pupil.
ISO speed The relative sensitivity of film provided as a benchmark by the International
Standards Organization (ISO). In digital cameras, the minimum ISO rating is defined by the
sensitivity of the digital image sensor. When the ISO setting on the camera is increased, allowing
the photographer to shoot in low-light situations, the camera amplifies the voltage received
from the light-sensitive elements on the digital image sensor prior to converting the voltage
signals to digital values. See also digital image sensor, digital noise.
