Hello everyone, This is my first year using LF equipment and I am seeking advice on weather rela ted concerns. I live in Western Canada at the foothills of the Rockies and the w inters can get quite cold here. (had a blizzard yesterday) Sometimes the tempera ture dips down into the minus 25 to minus 40 range. I may have opportunities dur ing these cold spells to take some wonderfully clear winter shots. My question i s can you advise me of things to watch out for or be careful about during these cold times ? I use a Calumet C400 view camera and a Super Angulon 90 lense. (as well as a 150 & 300 mm). Do I have any concerns with film or film holders ? Than ks in advance.
