Fake or real? If these are the words that your client or development team are using about a rendering of your product, then you know that is showing off your product well. Renderings don’t just have to be realistic but can be stylized, used to convey a message or show your product in an environment. For example, a rendering helps management conceptualize a new trade show design before going into production. Renderings can also help you make decisions about finishes or graphics on a product.
