Representational: This is a photograph that is on the representational visual level. When viewers see this photo they know that it is a photograph based on reality. These kind of representational images are the most reliable messages because people can relate to the realism of the photo. People have a strong connection to the photo. In this case people look at the photo and they actually see a house. They relate to it by saying, "I've seen one of those and I live in one of those.
Abstraction: This is an abstract image of a house. This image is abstract because it is not a realistic photograph. However, on a visual level people can still see that it is a representational picture of a house. The major difference in this image and the one above is that it has a reduction in the visual message. In this image people see the visual understructure of what represents a house. The triangle on top represents a roof, there are circles for windows, and a box for the foundation. Basically there is less information in this picture, yet there is still enough to see that it is a house.
Symbolic: This is a symbolic image of houses. The boxes are symbols because they don't look like houses or buildings yet people know that they are anyway. People can still understand that they are buildings because the lines represent streets because they are parrallel with eachother and the boxes are symbolically placed where buildings would go. This helps people understand that the boxes are coded information that symbolizes homes.
