Thanks for your reply David Apologies, I am a complete newbie, trying to learn fast.

I am a student making an animation / timelapse of photos and a painting appearing on a wall. Shooting outside with Arri 16 SR3 on Kodak 200 Daylight and fixed focus lens. Using a Cinamatography electronics intervalometer. So speed will be set at 1/2 second. Has anyone any advise to give as test shot will be out of the question. There will be changing light throught the day (unpredictable UK weather) but is it better to keep the aperture fixed ? If a fixed aperture is used what is the max variable reading in stops before I should be concerned about under/over exposure ? Using netural density filters if to bright and taking lightmeter readings...is this the same principle as still photography ? Is there any risk of light leaks apart from through the viewfinder ? Any advise would be appreciated
