For those that have gone to Alaska, what filters have you found to be a "must" for the trip? I'm trying to get what I need for my trip in June, but don't want to waste my money of useless filters that I can simply PP in after the fact. Thanks.
Polarizer. I lived in Alaska for a year and used only a CP. That was in the film days and I did some experimenting with a tobacco filter but generally a CP helps with the intense sun on sunny days and with color saturation on overcast days.
