Joint Photographic Experts Group (JPEG) - a file format that supports 24-bit color and preserves the broad range and subtle variations in brightness and hue found in photographs and other continuous-toned images.

L*a*b model (device independent) - L*a*b color consists of a luminance or lightness component (L) and two chromatic components: the a component (from green to red) and the b component (from blue to yellow).

Lossless compression - the techniques compress image data without removing detail.
Masks - let you isolate and protect areas of an image as you apply color changes, filters, or other effects to the rest of the image.
Optimization - process of fine-tuning the display quality and file size of an image for use on the Web or other online media.
Portable Document Format (PDF) - a flexible, cross-platform, cross-application file format. Based on the PostScript imaging model, PDF files accurately display and preserve fonts, page layouts, and both vector and bitmap graphics.
PICT - a file format is widely used among Mac OS graphics and page-layout applications as an intermediary file format for transferring images between applications.
Raster images (bitmap) - use a grid of colors known as pixels to represent images. Each pixel is assigned a specific location and color value.
 
 
word up

RGB model (additive colors) - A large percentage of the visible spectrum can be represented by mixing red, green, and blue (RGB) colored light in various proportions and intensities. Where the colors overlap, they create cyan, magenta, yellow, and white.

Slice - a rectangular area of an image that you can use to create links, rollovers, and animations in the resulting Web page. Dividing an image into slices lets you selectively optimize it for Web viewing.
Tagged-Image File Format (TIFF) - a flexible bitmap image format supported by virtually all paint, image-editing, and page-layout applications. It is used to exchange files between applications and computer platforms.
Unsharp masking, or USM - a traditional film compositing technique used to sharpen edges in an image. The Unsharp Mask filter corrects blurring introduced during photographing, scanning, resampling, or printing.
Vector graphics - Vectors describe an image according to its geometric characteristics. They are made up of lines and curves defined by mathematical objects called vectors.
Wabi-sabi - a beauty of things imperfect, impermanent, and incomplete. It is a beauty of things modest and humble. It is a beauty of things unconventional.
