Lake reflection

Working nearby I saw the wonderful reflection of the day light on the lake. No wind, no waves - perfect lake mirror. I grabbed my camera and the tripod and tried to seal this moment. What was my surprise when I saw on the computer zoomed the two white lines at the bottom of photography and realized that there were even the reflections traces of passed aircrafts on the sky. After this day I've never see such a clean and smooth day light reflection .
