Woke at 4.30 am this morning after spending an evening with friends. I quickly dressed drove down to the bay and captured a sunrise. After the sun rose I captured this image of the Mangrove Tree. Long exposure of 23 seconds. At 17 seconds with my camera set to Manual on Bulb I rotated the lens barrel back to 55 mm and then back to 18 mm again to create this zoom effect.
Canon EOS 500d
