Look at those colours

Our mundane Pacific Black Duck has a rather special patch on each wing called an iridescent speculum. Its plumage has a nanostructure that reflects light off at different wavelengths at different angles. Here by chance I was at the right angle to capture two colours. From another angle it can appear purple.

In post I added a global 0.4 EV to this one as I'd shot it a little low, so that iridescence came with the can.
