Occasionally I go to Kendal and do a supermarket shop. With a wet morning forecast it seemed a better alternative to housework.

Walking across Asda's car park in the rain I noticed coloured patterns from a fuel spill. Out came the mobile phone for a few shots before I had to move for a car. 

An increase in contrast and saturation gave the result above. The light area at the bottom is a different type of tarmac ........ nothing I could do about that.
