Shooting in winter has some abnormal challenges, one is really boring but turns out to be important. Condensation can really cause us issues if not nipped in the bud from the start. Condensation normally occurs when warm, moist air hits a cold surface. It can start as simply as our breathing on our gear and ice forming while shooting. The gear with that ice goes in your camera bag and once in your warm room, the condensation issue is born. To avoid this, I do these simple but I think important steps. When I put my gear away for the last time after shooting, the memory cards are removed and put into my pockets. Once I get into my room, I grab a clean bath towel and on the bed, I will lay out all my gear and quickly cover all of it with the towel. I then open all the section of my photopack, unzip them but have the flaps closed. I then put the cards in the computer to upload and then go eat. When I come back to the room and hour or more later, the gear normally has warmed up to room temp (never having the room above 70 degrees). Any condensation will have formed on the towel. I then clean the gear and put it back in the bag and put it all in the coldest corner of the room. Boring stuff, but simple and it’s never lets me down keeping my gear dry and operating even down to -32.
