I'm planning to shoot a documentary with a Panasonic GH4 without any external lights. If I set the shutter speed to "standard" 1/50 for 25fps, how can I control the lighting on the scene? If shutter speed is fixed, an indoor scene and outdoor scene can't be both well lighted. Or should I do it changing the aperture (and ISO)? When taking photo, you just change the shutter speed and thus getting more light into the photo.
Let's say I want to have a shallow depth of field close up of an object indoors and outdoors. How can I control that both shots are equally lighted maintaining the f-stop of the aperture for having a unfocused background? Is it possible at all?
Thanks a lot in advance!
