Not sure if this is done with real time lighting on the set, in post production on computers (if so I'd like to know with what program and effects), or in a blend of both, but it really adds to the atmosphere.
shareI agree!
Most ghost dramatizations are lame, but these people really know what they're doing. Not only post with the black and white but there is excellent filming. I first saw this today, with the episode where the old man's wife dies due to an asthma attack. When he is sitting on the chair next to the flower, it was BEAUTIFUL! Great filming and post!
