i have a bunch of driving scenes in my upcoming short film, and we'll be shooting those on a process trailer. any advice? i have both day and night shots. 2 actors in the front seats. mostly dialogue. i'll be using an ex1 with the stock lens (31mm at the wides), maybe a screw on wide angle adapter. will that be wide enough? will the window glare be an issue? anything i should be concerned about? thanks.
