I have been offered an opportunity next year that will entail a fair amount of travel by light aircraft. So, will be flying at fairly low level (not up with the big boys) and would appreciate any tips for taking photographs from a light aircraft. Will not be able to open door or window in flight so anticipate potential issues with trying to shoot through the window glass, maybe. Any advice or pointers to useful websites/magazine articles/books appreciated. Thank you in advance everybody.
