Does anyone have any ideas on a situation I have been confronted with on a film that is due to be shot on Super 16mm with a Bolex EBM?
Their is a scene where a beam of light is to shine through a crack in a wall and transfix an old man who is caught in it's beam. The effect that the director wants to achieve from either a neutral angle, or from the side, is that the beam of light should appear to have an almost 'material' quality to it, and that instead of just instantly enveloping the old man who is in it's path (as say a torch would when switched on and pointed at something), it should appear to advance slowly towards him.
Been scratching my head about this for some weeks so any help / insight would be greatly appreciated. Must stress though, that this effect must be achieved IN CAMERA if possible.
Thanks...
