PS is a "bitmap" image processing and manipulation program. It's ideally suited for creating, modifying and outputting digital images of a photographic nature, which share a common fundamental structure: pixels in a bitmap. Simplified, but primary operations would be: * Access / acquisition of digital graphics photographic in nature * Add, subtract, modify, colorize, pixels in the images

* Produce digital files where the whole image is part of a "fixed" pixel structure (the "bitmap") * Prepare complicated color/BW images for further processing in page layout programs for high resolution printing Fundamental difference: Photoshop manipulates individual color pixels within a fixed bitmap Adobe Illustrator

Illustrator is a vector-based postscript drawing program. It functions by generating curved paths (Bezier curves) connected by modifiable anchor points. These anchors, with their handles are ultimately editable, and never "leave" the structure of the file.       A vector based drawing program creates the various elements of the image as individual vector objects which retain their characteristics and do not become part of a "bitmap". Fundamental difference: Illustrator generates "vector objects" which are not part of a "bitmap"

photo shop is a computer pixel drawing program used mainly to create images that have complex texture and shading such as photographs and paintings - the other type of computer drawing program is line and shape based (vector drawing) and is better for drawing high precision images with lines and areas of flat color - photo shop can also do vector like drawing but it takes more time, is less precise, has fewer vector drawing tools and cannot be scaled up or down without damaging the image at least a little - photos and paintings in photo shop can be scaled up as much as 10 to 20 percent without noticeable damage but do that to a line drawing in photo shop and it looks horrible - photo shop is very intuitive and a natural drawing environment and so takes a lot less time to learn than a vector drawing program major uses for photo shop:

photograph manipulation
painting + drawing
graphic design + illustration + page layout
animation cells, sprites, and gif animations
web images
