Hello,

When lighting a room that you want to be somewhat dim do you need to underexpose a stop or two to get the desired effect? For example in a house you may light a kitchen brightly like at a 5.6 and expose for that but another room may be lit dimmer. So using more soft light and less powerful lamps lets say you get a 2.8. If you set your lens for that will the scene come out as it did to your eye or do you need to close down?

Also what would you do in a situation where someone is watching television? There face is only lit by the image on screen so I know you would probably need to set up a light or two to give the illusion that the television is the source of illumination but again would you expose at full key or underexpose?

Cheers
Anthony

Yes, for an effect where the highlights look underexposed, under key exposure, then you would underexpose the film -- but generally you tend to play it safe, for example, underexpose by one stop and then time it even darker in post if necessary. Just depends on the level of "dimness" you desire. If you are doing a shot of someone walking through a room with no electricty in a black-out yet wanted to see detail very dimly, you may have to underexpose a lot more.

Just remember that with film, it's easier to make things darker in post than lighter, so don't go overboard with the underexposure.
