Space is three-dimensional. Space in a work of 2-dimensional art, such as a photograph, refers to an illusion of depth or three dimensions. Space can be created in 2-Dimensional art by position, overlapping, size variation, color, and value
In this picture of an Aragon walkway, I see the Aragon walkway continuously going back with multiple lines heading toward the end of walkway. The space can gradually decreasing size of the lines. The decreasing size of walkway conveys a sense of dimension to me. This image is appealing to me because it feel like the image is a portal to the place in it.
