I'll be doing some glacier travel in the Northwest next summer and wondered if you had any suggestions for 35-millimeter film to capture the blues, whites, and grays. I'm looking for assistance choosing speed, brand, and even type of film. My camera doesn't have the capability of filters. Carl Vesper, St. Louis, Missouri Shooting on snow and ice poses a range of problems.
Various films respond differently, as well.
I recommend using Kodachrome transparency film. In my experience, it yields a little truer whites than Ektachrome or Fujichrome. That can be problematic, as those cameras have relatively unsophisticated meters. A film with a speed of 100 ASA will be fine. With that, you may have good results.
