Photos of flowers, plants, bugs, animals, birds, landscape, geology or whatever nature gives you room to breathe. Please be as informative or descriptive as you can about what a plant, animal or rock is. To me, education about nature is a strong part of knowing nature.
What is texture?
Texture goes beyond mere pattern or form into something more complex and organic that you could touch, feel and maybe even identify with your eyes closed if your hand were big or small enough. These are visual representations of a non-visual sense: touch.
