Coloured Lights

We were out all day, then came home to torrential rain late afternoon. When it stopped I had a play around with depth of field using my nifty fifty prime lens. I tried it on these coloured lights in the garden, some of which are full of water. I took lots of different apertures from f1.8 up to f11, but the one I liked best was f4, with just the blue lamp in focus.
