Introduction to Adobe Illustrator
Adobe Illustrator is an industry-standard vector graphics software used for creating logos, icons, typography, illustrations, and other digital artwork. Unlike raster-based programs (like Photoshop) that work with pixels, Illustrator uses mathematical equations to create art that can be scaled infinitely without losing quality—making it essential for design work that needs to appear at multiple sizes.
Core Concepts
Vector vs. Raster
Vector Graphics (Illustrator) | Raster Graphics (Photoshop) |
---|---|
Math-based paths and points | Pixel-based images |
Infinitely scalable | Fixed resolution |
Smaller file sizes | Larger file sizes |
Ideal for logos, illustrations | Better for photo editing |
File formats: AI, EPS, SVG, PDF | File formats: JPG, PNG, PSD |
