Converting the image to black and white emphasizes the shadows and shapes of light reflecting from the sculpture. The image was shot at a shutter speed of 1/100 with an aperture of f/20 (so it would be completely in focus) and ISO 1600, which produced a quality image with a reasonably good whole subject view. The photographer had to raise the ISO a little and make the shutter speed a little slower to prioritize the deeper depth of field (using the exposure triangle concept).
