Quoted from docquest:
Why does everyone keep crapping on Photoshop?
Don't they realize its just a tool to manipulate existing artwork which could be hand drawn or photographic?
Do people realize that the Ghotbusters art on the pinball machine was probably composited and edited using photoshop (or equivalent digital editing software).
Photoshop is a tool and like any tool it can be used with amazing results or horrible results depending on the skills of the user.
