The original photo had quite a soft, almost foggy look to it as it was shot in pouring rain. As I started processing it and adding contrast I noticed the huge change in the foreground colours, matching the paddock colours. The only explanation I have for it is that the colours of the paddocks are being reflected off the road or in the rain that is bouncing off the road. As it was a 30sec exposure the rain drops would have created a 'sheet' of water in front of the lens which is probably the most likely reason for the reflection. Looks cool. Only a couple of weeks old and this image is already on its way to an international conference for roading engineers via the NZTA.
