Complete Surprise

Today I was playing with the iPhone and the Hipstimatic App. When I was leaving the office to head home the light hitting the flags was very beautiful. I took a couple of shots but didn't really look at the results until now. I'm sort of blown away by the fact that I thought I chose a B&W "film" but the flag still has some desaturated color. What a happy surprise. What are the chances of recreating it!
