Consistent Exposure

I've found that when shooting in the same space, the exposure of my movies changes noticeably. Since there is no meter or scope in the camera, what are some of the ways to tighten up exposure?

Of course, I can step on them in post but my skills are not quite there yet.

Thanks,
Burt

There is a meter in the camera and it is viewable on the LCD screen or in the optical viewfinder. But your comment is somewhat confusing.

What do you mean "shooting in the same space". Do you mean in the same room? Are there factors like sunlight affecting your exposure? And what exactly does "tighten up exposure" mean? Do you mean make it more consistent?

What lens are you using to film?
A prime (which is set focal length like 135mm, or zoom which has a variable focal length say 50-200mm.
And if it's a variable focal length (zoom) lens then, is the lens a variable aperture like 3.5-5.6?

Or is it a constant aperture? This kind of lens will let you maintian the highest aperture setting all of the way through the zoom, say 1.4.

This is the only thing that I can figure that would make your exposure change in a room, except for the lighting obviously changing.

If I am in the same room and using natural light, when the subject is in different places the light is different. I've found if I leave the camera alone, not change any settings, the exposure difference is apparent on playback. I'm trying to match the reflected light from the skin if that makes any sense otherwise, the skin tone changes.

I'm using a 28-70L 2.8 and there is usually enough light so I can play around with settings.

Perrone, I don't know what you're referring to when you say there is a meter viewable on the LCD. I can see my settings but I don't see anything that gives me an idea what a good exposure is. Can you elaborate?

Thanks,
Burt
