[Note: I'm light years away from being an expert on video. This is a very basic question, and I believe the answer might be pretty simple too.] I have used camcorders only in a few occasions (and not extensively). All camcorders and digital cameras nowadays provide automatic exposure compensation, wherein the device automatically changes the exposure based on the amount of light coming in. When I shoot still pictures with a digital camera, this change in the exposure compensation is easy to deal with because I allow my camera to "settle in" and then I manually change the aperture or AE lock setting to suit how I want to capture the picture. How do professionals deal with such situations with video? Do they even use automatic exposure compensation in camcorders? If so, how would they deal with, say the following situation - while shooting something within a house, the camcorder is slowly moved around and in a few seconds passes over a glass window (or open door) in broad daylight, causing a sudden change in the amount of light (and thus upsetting the device's automatic exposure control if in automatic mode)? If not, how would they adjust the controls while shooting such a varying light situation? For a "planned" video (where the shoot is not continuous), I can think of using the same "settling time" to manually adjust the exposure and continuing with the shoot. For a spontaneous "live" one, I don't have any idea how to deal with this - the best that I can think of is to neatly chop off the "flaring transitions" while editing. Is there a better way? Additionally, any good pointers, information and book/resource references about shooting good quality videos would be appreciated. P.S.: My main use for a camcorder (in the future) would be to shoot home videos, travelogues and "home made documentaries".
