Structure relates to the arrangement of and relations between the parts or elements of something complex. It relates to the building or other object constructed materials, giving pattern or organization to.
Structure in nature originates from the design that occurs in nature . . . in molecules, in crystals, in living cells and more.
Structures can take the form of . . . new buildings, old buildings, equipment, statues and the list goes on.
I like photographing unique structures in unique locations.
