Meet Yukio Miyamoto – a grand master in using Adobe’s Illustrator. I will let his work speak for him.

All of these works started from scratch in Illustrator.

Now you might ask – what’s the difference between Adobe Photoshop and Illustrator? I borrowed the explanation from digital.tv

Photoshop is used in digital image editing that is pixel based, such as digital photographs. Illustrator is used to draw vector graphics such as logos, illustrations, line arts. Vector based drawings are scalable. They can be made into any size without losing resolution or details. All company logos are done in vector based drawings
