While photographing the famous U-Bein teak bridge at sunset on Lake Taungthaman in Myanmar I noticed these two old trees silhouetted against the sky. The smaller one looks to me like it is imitating the larger one.

Taken with a Canon EOS 5D Mark II camera, and EF24-105mm f/4L IS USM lens. 1/3000 second, f/5.6, 50mm zoom setting, ISO 400.
