"There are a ton of reasons Photoshop is one of the most preferred drawing programs out there for graphic designers. The program is powerful, allowing you to create and manipulate however you see fit, not to mention the various effects and filters available.
Photoshop can be used for many things which include making your portraits stand out. Vector and vexel portraits are so popular that there are even apps that quickly do the job for you. You can do the same thing in Photoshop however and even create a cool color combination to give your portrait its own unique feel."
