Photoshop® Elements 8 After the Shoot

Glossary

8-bit color

Uses eight bits per color channel to describe each pixel.

16-bit color

Uses sixteen bits per color channel to describe each pixel. Creates a file that is twice the size of an 8-bit file.

additive color

Describes the way light waves combine to create color. This is the way humans see things, and it's how most color adjustment happens in the Photoshop Elements Editor. This system is called additive because it begins with black (no light). A light source adds wavelengths that have a specific color. Equal amounts of pure red, green, and blue light added together create white. See also subtractive color.

Adobe Camera Raw (ACR)

A raw file converter that comes with Photoshop Elements that's used to convert raw files for editing. See also raw.

artifact

An unwanted visual distortion introduced by the digital process.

aspect ratio

The relationship of the height of an image to its width. For example, 4 × 5 is the same aspect ratio as 8 × 10.

banding

Occurs when intermediate tones are lost during the digital process. Because these tones are missing, color graduations appear as bands, rather than gentle tonal grades.

barrel distortion

Where the vertical or horizontal lines bulge away from the center of the image. This type of distortion is usually caused by using a wide-angle lens. See also pincushion distortion.

Bridge

Adobe Bridge is the file browser that comes with the Mac version of Photoshop Elements 8. It can be opened independently of the Editor. See also Organizer and Editor.
