Everywhere you look, there's another postcard shot when you're in Oia, Santorini, Greece. The whitewashed walls and brilliant blue-painted doors and roofs are a requirement for residents and the effect is astounding. This shot was taken during a port call on our Eastern Mediterranean cruise in November, 2012. Canon 5DmkIII / Canon EF 24-105mm f4L IS USM at 28mm / 1/320 sec / f11 / ISO 100.
