Texture
Texture can be defined as “the feel of an object's surface." This is an example of the way in which we often assume texture is something which must be physically felt in order to understand it. Texture is something which we feel when we interact with our surroundings. But, our understanding of texture is not limited to touch. Texture can be "felt" with our eyes also.

I think that these photos represent Texture because when you look at this wall and the tree, it seems like you can touch them and feel them with your hands.
