Okay, this is a great story. Meet Sean. Sean goes to the Geoscience Forum here in YK a week or so ago. He wins a beautiful, sparkly diamond from BHP Billiton's EKATI Diamond mine. He's shocked. He leaves forum. He drives directly to girlfriend's (Jenny) place of work. He proposes. She says yes. Bliss ensues.
Fast... forward a week or so. Beautiful cold morning, the frozen ice of Yellowknife Bay. Magic light. Magic couple.
Lighting info: this one was pretty simple. A single off-camera Canon 430EX Speedlite, about 2-feet to my left and angled slightly up (to avoid too much spill on the snow). Triggered by an on-camera Canon 580EX. No modifiers.
