hi, i plan on shooting some various time lapses this weekend with an Arri SR2 and a variable speed controller. Do i need to compensate if i shoot a slow frame rate like 1 frame every 5 seconds or so? Would i need to close way down and compensate or is it like shooting a still photograph with a normal exposure? i've never shot time lapse on 16mm so any advice would help. thanks Drew
