It was purely accidental. Or at least a part of it was. It started with my fascination to take a picture of twin items next to each other, suggesting one of them to be more prominent than the other. My plan to accomplish this was to find two items of the same kind standing side by side, one of them slightly further away from the lens. With an appropriate depth of field, one should be in focus and the other blurry while appearing almost of the same size.
