There is such wonderful strength and beauty in the design of these columns. I wanted to create a composition that emphasized the repeating shapes. You can do this by filling the frame using a zoom lens. This will help eliminate any background distractions, and allows you to make a compelling image that best features your subject.
For this image, I focused on the first column using a 70-200mm lens at f/2.8. This allowed the rest of the columns to fall into a soft blur, while the first is in sharp focus. This generates a little more depth and drama, and an interesting push-pull tension between the sharp and blurred areas.
Alternatively, stopping down to a smaller aperture such as f/16 allows all the columns to be in sharp focus, which gives you another way to tell your story!
Have fun shooting!
