For some, rendering is more than an image shown to a client to help them perceive a design. Joel is a 3D artist who explores design through digital rendering/computational work. His ability to render opened up his mind and changed the way that he viewed his designs.

The final stages spent in Photoshop can change the mood and emotion within the image.
