In the presentation by Beau Otto on Optical Illusions, he talks about how everything we see is not real, we only see things how they are perceived by our own eyes. A real life example of this is advertisements. Companies take different objects and put them in their adds to help their product look better to the human brain. If the advertisement is an add about a cruise ship, they will take a family smiling and having a blast, with a clear blue sky and the sun shining. Everything in the commercial is happy and everyone is having fun. This makes a person watching the commercial want to go on the trip because it looks like the most exciting thing in the whole world. Another example is photo shop into pictures. Movie producers will take a green screen so that they can change the background into the perfect background so that the viewer can enjoy the movie and so that the weather outside in movies is the way the producers want it. All things in life can be perceived differently be each and every human, and this is why everything we see is not real.
