This week’s challenge is triangles. A chest X-ray selection wasn’t problematic because just about every segment or lobe of the lung either consolidates or collapses to form a triangle. With this in mind I chose a partial collapse of part of the upper lobe on the right side which formed a nice triangle. The area concerned is not noticeable on this image because the collapsed part of lung goes white and that melds with the background.
Selecting triangles to complement the X-ray was more difficult. I photographed a polished crystal from a variety of angles and blew up the pictures to choose three which were then layered and blended. They produced most satisfactory triangles upon triangles. The image reminds me of looking down a kaleidoscope.
