How is exposure changed perfectly during a single take following someone going from a bright exterior to a much darker interior? It can't just be the aperture because that would cause a noticeable shift in depth of field, right?
Maybe I am missing something, I heard somethibg about "shutter angle change" but am not to familiar with how that works. Any help would be great!

The only way is to manually adjust while shooting. I've never set up a shot which required me to do so, but It would be as precisely choreographed as any action on screen. Similar to pulling focus I would imagine.
All else I can say on the matter is, without changing exposure, the bright environment will make the darker environment look darker. Lighting in the darker environment can be manipulated until a happy middle ground can be achieved.
Ex. Scene transitions from bright front yard to indoors. Strategically place halogen lamps (sunlight color temp) inside to compensate for underexposure. The scene was initially balanced for bright sun, and artificial sunlight has now been added to the interior. That is the extent of what I've done in regard to your topic.
Thank you SO much for your very helpful reply! I have been experimeting with lighting for some time now but find that that is what I have the most trouble with. Natural light works well outside but the transition from exterior to interior is where I get in trouble. I'll try what you said about placing halogen lamps. Thank you again, chunkiefroth.
shareAlso. . . If your interior has environmental lighting like lamps or light fixtures that are going to be shown, get some halogen bulbs for these. Traditional tungsten bulbs will give a reddish tint to shots balanced for sunlight.
shareI agree with manually adjusting aperture during the take. A lab or digital post-production adjustment could make the change somewhat, but there's only so much exposure lattitude there.
Also, most of those "following" shots are performed through a wide-angle lens, where depth of field isn't as much of an issue as a normal or telephoto lens.
