Circular and linear lines form a great contrast besides the color contrast in this image. Enjoy and keep on looking and photographing!
Another example of an aged wood pattern. Enjoy and keep on photographing!
Go out and photograph old board. You can find many old wooden fences in California where you can do this exercise. Or you can look for old wood structures.
I photographed this exercise in Bodie, CA, a ghost town where there are many interesting buildings. As always, enjoy this exercise.
