I decided to once again produce a questionnaire containing four images. Again, three of these were photographs, and the other was a computer-generated image by Alex Roman. Participants were asked to pick one image out of the four that they believed to be computer-generated and to give any reasons for their choice.
Results showed that out of the people who participated, a very low twenty percent of them correctly chose photo A as the computer-generated image. The main reasons given for choosing photo A were that the lighting and focus were not accurate, as well as some of the photo being blurred. In the image, Alex Roman has tried to give the illusion of filmed reality by adjusting the focus using depth of field. Eighty percent of participants were fooled into picking B, C or D, suggesting that computer-generated imagery can convince people by showing techniques used in photography. People who picked the wrong image gave reasons such as the textures not looking real and the images looking "cut-out". From this, it shows that Roman's image effectively mimics reality to fool the majority of people.
