I do check that the film is aligned on its rails while the back door is open. I know I don't have to, but I just like to. It's a comfortable ritual. If I were to use the bottom plate to align the film, I'd still have to take the bottom back off and open the back door to admire the properly positioned film. If I didn't, I'd feel deprived of an important part of enjoying my Leicas. Rituals are important in today's complex changing world. As the Tiffany's salesman said, in Breakfast At Tiffany's, "It gives you a feeling of continuity, almost of solidarity, with the past."
