Digital art technology allows for art to be created digitally using computer tools and software. This has opened up new possibilities for art that can appear unbelievable. There are two main types of computer-based art - computer-assisted art which uses applications like Photoshop as a tool, and computer-created art which is generated algorithmically. While classical and digital art both start with an artist's idea, they use different media - classical uses tools like paintbrushes while digital uses software.
