This is Serra da Leba, a landmark in Angola. A road built in the 70's, it's been in the country's postcard images for decades, but all shots were taken by day. I wanted something different and tried a night shot. But it seemed impossible: pitch dark, foggy, altitude of 1,800m (5,000ft). I wanted no more than 60sec of exposure, max, to avoid digital noise. But a car takes a few minutes to climb or descend this section of the road. The fog was dense and blocking the view! Suddenly the fog cleared, a few cars went down, others went up and in under 60 seconds the painting was done!
