Developed and contact printed the negatives tonight. A couple of decent efforts but they all suffer from basic exposure and composition errors, none of them I am happy with.

I'll head out with my Fuji 6x9 next time, I can operate much quicker with that camera in the extreme cold as I don't carry my light meter or even focus it much, normally it is Sunny 16 and zone focus. I don't think my Pentax's motor drive would be happy at those temperatures.
