I get very annoyed when the blinds are put down on a day-into-night flight ... after all why would I ask for a window seat if I didn't want to look out of it? This is very true on the LHR-BOM flight (day) where am dept leads to a post-midnight arrival. I'm an amateur photographer too, so if I want to take sunset at 35000ft, for goodness sake let me (unless the seatbelt signs are turned on ...)
