On the 24th of November I am flying to LHR from ATH. I want to take cockpit, cabin and wing views but my flight departs at 19:10 local and it will already be dark (Dusk). Is there any good film of 800 or 1600 iso that you would reccomend? I have heard that Fuji's X-tra 800 and 1600 have finer grain than others. What else should I consider? Maybe pusing?
