I myself is directing and acting a couple of night scene for a small 20min project. Using a filter would be an option but it need proper adjustment to the setting or the dark scene would look faked.
The difference on filming a night scene in the day and in the night is, the surrounding sound of crickets and silence in the air. In the day, too much additional noises which would make you do extra work just to filter those sound.
For myself, what was taugh by a friend who does professional filming, was to use a huge board, covered it with an aluminum wrapper (make sure it's not crumpled) and using a strong spotlight (probably the big yellow torches).
Flash the light on to the wrapped board, making it reflect the light to the surroundings. It only covers a few portion of the area though, so you got to have additional helper with addition boards and torches to emit lights to areas you want to film.
It nothing much but I hope this information helps those budget film makers who are tight with funding.
