Hi y'all,
What the heck is "obelisking" It's just a descriptive term used for dragonflies pointing their hind ends towards the sun...
Mexican Amberwing Dragonfly (Perithemis intensa) Canon EOS Rebel XT with Canon EF 70-300mm IS lens set at 300mm, 25mm extension tube, ISO 200, 1/125 sec @ f 13, natural light, handheld with IS turned on.
"Obelisking" helps the dragonfly regulate its body temperature when things start heating up. By pointing their hineys at the sun the dragonfly exposes the minimum surface area of its body to reduce heat absorption. I'm going to try that myself tomorrow when I go shooting at the Desert Botanical Gardens. Do you think anyone will notice
Best regards to all as always,
Mexican Amberwing dragonfly obelisking...

Nice image Tom. I have heard of an obelisk but not obelisking. Some folks have a behind so big it could cool an entire neighborhood An interesting fact though, didn't know that.

I really like this shot. Great colors, great sharpness, and the shape and gradation of the background is a really nice complement to the dragonfly.
I'd say the whole picture is "pretty close to perfect", but I don't have a clue what could be improved!
