This is one of the images in today's Technique Tuesday episode below. For me, the attraction to this subject matter were the three dimensional rectangular and triangular shapes of this building. The final crop isolated on those shapes and forms very effectively. Also, notice how the entire image is a fun play of three simple colors. The primary white against the dark blue is eye catching in its own right, but the little triangle of red is really where the eye stops - the "captured" reed has no place to go and becomes the main focal point of the image. Camera specs; Canon 7D fitted with 18-200mm IS lens at 200mm, F3.5 @ 1/8000 second (I missed resetting the aperture here. I was too wrapped up in the shot. Luckily the working distance kept everything in sharp focus.) ISO 200.
