What is the difference between Photoshop, InDesign and Illustrator?

I have used Photoshop and InDesign but I have CS3 now and it has everything. I am trying to figure out how to use all 3 for what they are used best for.What is the difference between Photoshop, InDesign and Illustrator?
InDesign is mainly used to organize text/images and design layouts like you see on magazine pages, newsletters, etc.





Illustrator is usually used for ';vector'; graphics where you create shapes or text (usually of solid color or with gradients) that don't lose quality when you enlarge or shrink the image. It is best for making logos or graphics.





Photoshop can also create vector images, but not nearly as well as illustrator. Photoshop is usually used for editing ';pixel'; based images such as a photo or a scanned image, which illustrator cannot do. Unlike vector graphics, enlarging and shrinking a photo will reduce the quality of the photo.

Photoshop is a graphics editor, market leader in professional image manipulation. Illustrator is a vector-based drawing program and InDesign is a desktop publishing application.

CS3 is awesome in that you can move between all its programs seemlessly. You can do almost everything in all 3. But overall, Photoshop is a visual editing and alteration tool. Most of the time, it's used to edit/alter photos. Illustrator is used for vector drawing because it doesn't pixelate your vectors like in Photoshop. InDesign is a pagination and ';desktop publishing'; program that allows you to create multiple pages in one document.
