The creative process used by Frederic Eugene Ives offers a perfect example of these five steps in action.
First, Ives gathered new material. He spent two years working as a printer’s apprentice and then four years running the photographic laboratory at Cornell University. These experiences gave him a lot of material to draw upon and make associations between photography and printing.
Second, Ives began to mentally work over everything he learned. By 1878, Ives was spending nearly all of his time experimenting with new techniques. He was constantly tinkering and experimenting with different ways of putting ideas together.
Third, Ives stepped away from the problem. In this case, he went to sleep for a few hours before his flash of insight. Letting creative challenges sit for longer periods of time can work as well. Regardless of how long you step away, you need to do something that interests you and takes your mind off of the problem.
Fourth, his idea returned to him. Ives awoke with the solution to his problem laid out before him. (On a personal note, I often find creative ideas hit me just as I am lying down for sleep. Once I give my brain permission to stop working for the day, the solution appears easily.)
Finally, Ives continued to revise his idea for years. In fact, he improved so many aspects of the process he filed a second patent. This is a critical point and is often overlooked. It can be easy to fall in love with the initial version of your idea, but great ideas always evolve.
