I would imagine it will be difficult for her to get processing and replacement film up there, and an extra challenge to share her work.
As much as I like the look and nostalgia of film, It's really a nuisance, unless there is a specific goal in mind.
I would think a good, simple, rugged P&S digital would be a better alternative, If a person can survive in the climate, a decent modern camera will do well too.
I largely agree with this comment. I worked as a professional photographer in Yellowknife for 20 years as well as part-time free-lancing in the North for quite a while prior to that.
I'll add that small camera batteries do fade pretty quickly in the cold, so it would be best to keep it in a warm pocket most of the time and just pop it out when taking pictures. Lens fogging when the camera is returned to the pocket can be a problem if this is done repeatedly over a short period of time, but it can be worked around.
As for film cameras in extreme cold in general, I'll offer a few opinions.
Most film cameras are getting fairly old. Lubricants may have deteriorated, which tends to affect cold weather performance quite a bit. The degree of deterioration is affected by the camera's history, so it is almost impossible to predict the cold weather behaviour of a particular body.
There is a good deal of variability in the cold weather performance of cameras with lubricants in as-new condition. For example, one commenter reported that in his experience bodies and batteries tended to crap out by -20. This was in the 1970s. The lubricants in those cameras were probably not the best.
I have a great deal of experience shooting film at -40 and colder. I had no mechanical problems with the cameras that I chose to use long-term. Some other cameras did tend to quit at about -20 to -25. The keepers received no special winterization. I did once have a Pentax MX "winterized" by what was supposed to be a top-notch service. Its cold weather performance worsened by 5 degrees versus the OEM lubricants. The shutter gummed up at about -30 instead of -35.
The meters worked most of the time to below 40, although they were unreliable enough that I carried a Sekonic selenium-cell meter as a backup.
Pentax has historically used very good lubricants in their lenses. Apart from moderate stiffening of focus, I have never had a problem with an MF Pentax lens even in the coldest weather.
My most reliable mechanical SLRs have been bodies with Copal Square shutters. I have a Ricoh XR1-s that worked beautifully below -40. It was my main cold weather body for 15 years and is still in good working order. My coldest temperature record was -52C, with a screwmount body using a Copal Square.
I've also had good results shooting Pentax Super Programs with external battery packs. They kept going happily to below -40.
My experience with AF film cameras has been mainly with midrange Nikon bodies. The coldest I've used them was the low -30s. They were fine as long as I kept changing batteries every half-hour or so. Lenses were no problem.
Hope you find this useful.
