Vectors.

Think about it. At some point in your high school math career, you have learned about vectors. You know, those annoying things with the carrot notations <0,0> blahblah.

So yes, that’s exactly what a vector is: math.

In Adobe Illustrator, you create images using vectors. In Adobe Photoshop, you create them using pixels. Pixels are tiny squares. You’ll notice that when you zoom too closely into a regular photo or something you make in Photoshop, the quality becomes grainy and you can’t even tell what it is anymore. Eventually, all you’ll see is a bunch of colored squares.

Unlike Photoshop’s pixels, Illustrator’s vectors allow you to resize without losing quality. Even when you zoom in 38593%, you will have the same thing because it scales itself.

Of course going over the technicalities of art is like perfecting the tassels on a rug (aka pointless to the majority of the population), but it cannot be ignored.

I guess I understand that lines are blurred when things aren’t necessarily defined and such. Oh well! The more you know :)
