3D rendering, 3D visualization, 3D photography, photo-realistic rendering, there are many different names to call what we do - all at the end is artwork, we just use the computer as a medium. There are no magic buttons that creates an image - it is an intricate and complex process combining different components and techniques. There’s also the creative human behind this artistic process to produce an image, and using a computer doesn’t make the process any different from an artist painting his masterpiece.
