RAW
An image file format. RAW files contain all of the image data that was captured by your digital
camera's sensor. RAW files are not processed by your camera; instead, you must process RAW
images using a RAW processor.
recursive
Program or task that can repeat itself indefinitely, such as a slide show.
red-eye
Red-eye occurs when the light from your digital camera's flash reflects off the retinas in the
subject's eyes. The subject's eyes look red instead of their normal color.
Relative Colorimetric
Rendering intent that maps the colors that fall exactly within the color gamuts of both the input
and output devices. Best used for single- or limited-color images as colors outside of both
gamuts may be mapped to a single color.
render
Drawing images to your screen.
rendering intent
Approach used to map colors from one color gamut to another. There are four rendering intents
available: Perceptual, Relative Colorimetric, Saturation, and Absolute Colorimetric.
resolution
Quality and clarity of an image, measured in pixels, dots per inch, or pixels per inch.
RGB
Color model that uses red, green, and blue as its primary colors.
ringing artifacts
Distortion around the edges of image subjects, caused by compressing or resizing an image.
S
sample
Audio wave, measured in bits. More sample bits result in higher clarity and fidelity.
sample rate
Number of samples, measured in Hertz (Hz - cycles per second), to represent a sound digitally.
More samples per second result in a more accurate digital representation of the sound. An
audio recording’s sample rate is a key factor determining its overall sound quality.
sample size
Size of an audio sample, measured in bits.
saturation
Purity of a color. Higher color saturation results in more gray.
