I coming up on my first winter to use my large format equipment and would hope f or some cross country skiing and outdoor work. Often the contents of my pack re ach sub-freezing temperatures, which causes a variety of paranoid thoughts. The se include condensation on the film, frozen shutters, cracking bellows, lens fog ging, and so forth. Do others take specials precautions or have concerns about these, or have I been drinking too much coffee. Thanks much.
