Jpeg = Joint Photographic Experts Group
Format that offers 24-bit compression of images with subtle gradations. Ideal for photographic images. Lossy
Gif = Graphic Interchange Format.
A bitmapped color graphics file format. It employs an efficient compression method of solid color based art. Lossless
Tagged Image File Format
Photoshop file format
After Effects file format
Determines the color module used in displaying and printing images.
ImageReady uses RGB mode to work with images.
HSB (hue, saturation, brightness)
RGB (red, green, blue)
CMYK (cyan, magenta, yellow, black)
System software developed by Apple Computer for presentation of desktop video.
Generally refers to the resolution of computer monitors. Average = 72 dpi
Generally refers to solid color art, such as, Illustrations, cartoons, logos, type.
Reduction of the amount of data required to re-create an original file, graphic, or movie.
Frames per Second.
A movie contains a certain number of frames, and the fewer frames, the more jerky the motion and the smaller the file.
The positioning of different colored pixels within an image that uses a 256-color palette to simulate a color that does not exist in the palette.
Process of reducing colors to 256 or les without dithering. Produces areas of solid color and generates a posterized effect.
Is used to convert the image to 256 colors based on existing colors within the image.
The number of bits used to represent the color of each pixel in a given movie or still image.
bit depth of 2 = black and white
bit depth of 4 = 16 colors or grays
bit depth of 8 = 256 colors or grays
bit depth of 24 = approximately 16 million
This mode uses one of two color values (black or white) to represent the pixels in an image. Images in Bitmap mode are called bitmapped 1-bit images because they have a bit depth of 1.
Graphics that are pixel based, as opposed to object oriented.
Computer Monitor = 640 x 480 pixels
Red, Green, and Blue (light) - Used for color viewed on screen.
Cyan, Magenta, Yellow, and Black (pigment) - Used in print production for output.
