Sitting at the dinner table I noticed a rather unusual shot!
This is a macro picture of a small clear glass dish, containing Pure Olive Oil (for dressing a salad). The brown colour is the mahogany dining table, the pink colour (don’t ask!) is a rather ‘loud’ coloured napkin, both as seen through the clear glass dish.
The large circular shape is an air bubble, with a splash of water floating on top of the Olive Oil. The pink in the air bubble is simply a reflection of the napkin (easy really)! see: http://en.wikipedia.org/wiki/Refraction
