In an earlier blog, I mentioned a trip to the Arctic that ultimately had to be postponed due to adverse weather conditions. I needed snow but in November and December it rained. In January I was traveling to the bottom of the globe in Antarctica but now in April, I am finally shooting outside of Iqaluit, Nunavut in the northernmost reaches of Canada. The temperature has been hovering around -22C with winds blowing at 20-30 kph. Although keeping personally warm is paramount, my bigger concern is keeping my battery operated gear from freezing. Fortunately my Canon 5D Mark IIs have been operating really well, although I do warm a few extra batteries with my body heat inside of my coat, in the event I need to change them. My biggest concern however has been my battery operated strobes, essential pieces of equipment that I need for the photo I am here to shoot.
I am using the Profoto Acute Bs, a six hundred watt second pack that has always been reliable. But in this extreme climate I worry that the cold may quickly drain the batteries. Fortunately I brought along Alex Stricker, my friend and fellow photographer to lend a hand. Dragging Alex from the warmth of Phoenix to the cold of the Arctic took some creative coaxing and it was well worth it. Besides his photographic abilities Alex is incredibly talented when it comes to building and prepping anything needed for a complicated shot. In this case, we needed to find a way to keep the Profoto batteries warm and Alex as usually came up with a creative solution.
We bought a midsized, styrofoam cooler (rather ironic for our geographical location) and lined the insides with the eight hour, hand warmer packets I had brought from New York. We placed the strobe unit and two spare batteries inside of the cooler, notched out a hole on the lid, and ran the cable through it to the strobe head. To provide additional insulation, we lined the bottom of the cooler with a silver, space blanket. Before I took the cooler into the cold I walked fifty feet down my hotel corridor with my pocket wizard radio tripper to ensure the strobe would fire. It did.
We felt like we were setting up for a tailgate party when we finally brought the cooler outside only instead of fall football weather, it was -23 C, dog sledging weather. But our heated cooler worked great. We were able to get approximately 150 full power shots off each battery and when we finished shooting, the inside of the cooler was still nice and warm; a lot warmer in fact than either Alex or I.
