Illustrator is a powerful tool, but it’s limited to certain types of tasks. Knowing what Illustrator does best is key to getting the most out of the software.
Illustrator does anything having to do with path-based artwork extremely well and performs beyond the basics with pixel-based artwork. You can use Illustrator for page layout, but it really isn’t designed for documents longer than a single page. You can also use Illustrator for some basic image adjustment, but that sort of thing is easier with Photoshop.
Any time you want to create art or graphics pieces that need to serve multiple purposes, use Illustrator. Illustrator’s flexibility in transforming artwork is second to none — with equal ease, you can create artwork to appear on a business card, a bottle label, a poster, a billboard, television or film, or on the Web.
Illustrator isn’t limited to portraying the way things are in the real world. ?You can use it to create things that may have no real-world equivalents. Give light bulbs spikes. Create a monster out of eyeballs. Whatever you imagine, Illustrator can help you create an image of it.
