Hello everyone !

I'm a bit of a newby in large format photography, I've been doing some for about a year in normal condition. But now this is getting serious and I'm going for a trip in Northern Canada, near Inuvik, for about 1 month. And my question is about the extremely cold temperatures I'll be facing (about -22°F or -30°C). I think I will be okay but my really worries is for my cameras. I'll be leaving with a Fuji GS 645 and a Graflex equiped with a Optar 135mm 4,7 (which I haven't buy yet). I'll be using some Kodak portra films with the first and some Kodak Ektachrome with the second.

How do you think should I protect the films? (I thought of congelation bags we use for food but I'm really not sure) And the cameras? A friend told me that with those mechanical cameras, the oil could freeze and then the camera refuses to shoot. What can I do to prepare them to such cold?

I hope really much somebody can help me.

Thank you very much in advance,

Cheers,

Téo
