Frosty Field Surprise

Went walking this morning with only a phone for pictures. Last night people were saying how we never get frosts anymore. Well .... we did today. Pity was that half of it had melted by the time we'd reached the park. Aaaaanyway I was fooling about with the image - doodling really - when I happened upon Nik's Solarisation filter. The result was so striking that I had to share. The original is the extra.
