Shooting in Quebec in February was a very cold experience. It was around –15 degrees Celsius on average in the mornings. This equates to 5 degrees in Fahrenheit. So, yes, it was cold. How do you stay warm? We all know the basics: dress in layers, wear cloths that wick away sweat, wear a windbreaker . . . but are you looking for a comprehensive list with specific  brands and detailed recommendations from the perspective of a photographer? I don’t have the experience to be able to put together a list like this yet, but I can point you to someone who does. I ran across this excellent article, How to Photograph in Winter Conditions Without Being Miserable by Sarah Marino on the Dreamscapes Team blog today and thought it to be very appropriate for this time of year, especially at this unusually cold year.
