The Element of Texture in an Image

On my evening run I made several images and this one was a pleasant surprise. I initially wanted to get a view of my favorite subject, Table Mountain, from a low vantage point, with a sweeping view of the beach in the foreground. When I got home and looked at the image on the computer, I immediately realized that what I captured really was not about Table Mountain, but of the texture of the sand in the foreground. While the mountain is there and is certainly pleasing, I was more interested on how you could see the individual grains of sand which is the texture in the image. Surprisingly enough, I got this amount of detail with my iPhone. 75/365.
