Eye to Eye with a dragonfly

I took a trip to the London Wetland Centre today, my hope for the day was to get a photo of a Dragonfly and a Common Lizard.
Although I did find a Common Lizard it wasn't in a photogenic setting so I just had to admire it and move on.
Although there quite a few dragonflies flying the sunny weather seemd to mean they didn't need to rest so much. I did try to photograph them in flight but the less said about that the better!
I spotted one dragonfly alighting on a log, it flew away and a few minutes later it returned. As it seemed I had found it's 'favourite' spot I got my tripod set up and settled in to wait. I decided to use the 300mm f4 L with a 1.4x extender as this works well for dragonflies at it's minimum focussing distance of 1.5m. I decided on an aperture of f18 to give a reasonable depth of field but still give a nice out of focus background.
The 'session' lasted about 45 minutes with the dragonfly returning periodically, this was my favourite shot from the session.
