Apple Aperture 3.5 - Manual (Page 520)

Glossary 520
rangefinder An apparatus found on many cameras that is used to help focus the image. See also
camera, viewfinder.
raster image processor (RIP) A specialized printer driver that replaces the driver that comes with
your printer. The RIP takes input from applications and converts, or rasterizes, the information to
data that the printer understands so that it can put dots on a page. Software RIPs typically offer
features not found in standard printer drivers.
rating In Aperture, the process of adding a value to a photo to indicate its quality in relation to
other photos in a selection. See also photo edit, Reject rating, Select rating.
RAW The original bit-for-bit digital image file captured by the camera. See also RAW + JPEG
image pair.
RAW Fine Tuning adjustment A set of adjustment parameters in Aperture used to control how
Aperture decodes RAW image files. See also moire pattern.
RAW + JPEG image pair A photo captured by a professional digital camera and saved as both
an individual RAW file and an individual JPEG file. You can set Aperture to import one file type or
both file types in the pair. See also JPEG, RAW.
reciprocity The relationship between the aperture and the shutter that allows for correct
exposures as a result of multiple shutter speed and aperture setting combinations. An increase
in aperture and a decrease in shutter speed creates the same exposure as the previous aperture
and shutter combination, and vice versa. See also aperture, shutter.
Recovery parameter An Exposure adjustment parameter in Aperture used to recover highlight
detail. See also Exposure adjustment.
red-eye The phenomenon that gives people glowing red eyes in photographs. Red-eye is
caused by the close proximity of the flash to the lens (especially built-in flash). See also external
flash, Red Eye Correction adjustment.
Red Eye Correction adjustment An adjustment in Aperture that replaces red pixels with black,
eliminating the red-eye effect. Used in conjunction with the Red Eye tool. See also adjustment,
pixel, red-eye.
referenced images Images whose originals are stored outside of the Aperture library. See also
library, managed images, offline, online, original.
Reject rating In Aperture, a negative rating applied to a photo as part of the photo editing
process. See also photo edit, rating, Select rating.
relative colorimetric A rendering intent suitable for printing photographic images. It compares
the highlight values of the source color space to that of the destination color space and shifts
out-of-gamut colors to the closest reproducible color in the destination color space. This
rendering intent can cause two colors, which appear different in the source color space, to
be the same in the target color space, which is known as clipping. See also gamut, perceptual,
rendering intent.
rendering intent The method by which colors that are out of gamut for a selected output
device are mapped to that device’s reproducible gamut. See also gamut, perceptual,
relative colorimetric.
