Jeff, Bev, thank you for the comments. Actually, that was a late afternoon shot with the low angle of the sun. I think that is the reason for yellow-red tones. I used my "heavy old" Vivitar 200mm tele-lens to take this photo, and the aperture was maximally closed. Shutter speed was 1/1000, but the amount of light was again too much even with this aperture. I did a postwork, diminished the light, and increased the saturation and contrast a little. I think the final overcontrasting increases the geometrical appearance.
