I am going to Montana with my girlfriend to visit my parents. They live in a VERY rural town of about 300 people. A friend has offered to take us up in his plane to see the town from above. My questions are these: What lens and filters would you recommend? I will use black and white film, and have a cannon rebel with a 28-70mm lens. Will this be all I need? How can I get a nice grain effect that doesn't look like I just used cheap film, but will not destroy the picture. I am thinking of buying a holga medium format camera. They are cheap and I like look they produce. This might be one of the cameras I take with me. Any advice to taking pictures out of a plane would also be helpful.
