The photo uses space as in when you look at the sign it looks like the clouds are right above the sign but in reality its probably miles away. Space is represented by the background images ; you can see that the house has a triangular shape, the same as the sign and the tree. Also far in the corner you can see cars that are really far down you can barley see them. I think the whole picture is in focus but its just that there are things that are in a far distance. The sign were it has the cloud floating above the it looks really close but its not. How did the photographer take that photo at that exact time.
