Glossary
Last updated 7/26/2011
PSD The native file format of Adobe Photoshop and Adobe Photoshop Elements.
PSE The file format for saving and opening multiple pages as a single file in Adobe Photoshop Elements. Photoshop
and other editors will open the individual PSDs that compose the PSE.
Q
QuickTime Software from Apple that allows you to view movies and other multi-media files on your computer.
R
RAID Redundant Array of Independent Disks, a category of disk drives that use two or more drives at the same time
to improve performance and ensure a graceful response in the event of a hardware or software failure.
raster image See “bitmap image” on page 291.
rasterizer The engine in Photoshop Elements that converts vector data, such as text, to bitmap data.
red eye The reflection of the camera flash from the retina of a photographed subject, resulting in a red dot in the
subject’s eye. You can eliminate it automatically when you import images or by using the Red Eye Removal tool.
Rename Multiple Files Allows you to automatically rename several files at once. Available with the Process Multiple
Files command.
rendering Converting a vector layer such as a shape layer or a text layer into a normal layer. To convert a vector layer
into a normal layer, choose Layer
> Simplify Layer.
renmoji See “tate-chuu-yoko” on page 302.
resample To change the resolution of an image by changing its pixel dimensions. Downsampling is decreasing the
number of pixels, and resampling up (or upsampling) is increasing the number.
resolution A measure of the clarity and sharpness of an image. In digital images, it is measured in pixels per inch. (See
also
“monitor resolution” on page 298 and “printer resolution” on page 299.)
resolution independence Lets an image be resized without changing its resolution. In a typical bitmap image, pixel
resolution is fixed, so if you enlarge the image, quality is reduced. With resolution independence, however, an image
isn't rendered into pixels until it is simplified or printed.
reticulation A traditional photographic effect caused by the rapid changing of the film emulsion from hot to cold (hot
developer to cold fixer). It produces a random pattern of lines in a photographic image, less fine than craquelure.
revert The command that reverts the image to the last saved version.
RGB A model for representing colors on a computer display. Red, green, and blue (RGB) are combined in different
proportions to represent any color. The RGB model can represent 256 x 256 x 256 colors.
RGB working space profile A color profile that defines an RGB working space, such as that for a digital camera or
scanner.
RLE (run length encoding) A lossless technique for compressing the transparent portions of each layer in images. (See
also
“lossless compression” on page 297.)
S
sample To select a color with the eyedropper in order to use it with a drawing or painting tool.
saturation The purity, or strength, of a color. A fully saturated color contains no gray. Saturation controls make colors
more vivid (less black or white added) or more muted (more black or white added).
