Definition - Texture

Texture: 

The feel, appearance, or consistency of a surface or a substance.

My own definition:

The physical structure of a surface determining the way it feels.

In this picture, shadows are used to bring out the element of texture. The shadows are smooth an undisturbed; this gives the viewer the impression that the texture of the rocks are smooth and pleasant to touch, which is unexpected as the viewer would have most probably thought that the rocks would be rough.

The photographer has zoomed in on this picture, allowing the viewer to see the details of the fur. By looking at this, it is evident that the fur is smooth and well kept - this has been made clear by the close up that has been provided of this animal.

Once more, this picture has been zoomed into as the viewer can see the details and almost feel the soft material on their skin. A pattern is created by this material and this further allows the viewer to imagine what this would feel like if they touched it.

This picture has been edited and sharpened. The photographer has done this deliberately so that the viewer can feel the leaf in their hands. By sharpening the picture, the photographer has allowed the viewer to be able to see every detail of the leaf and making it seem more realistic to the viewer.
