well you need a special filter for that: a 10 stop neutral density filter.

Just a moment of creativity. The hardest part was the waiting for the filter: took 3 weeks.

dimming the tv-screen would give a longer shutter time (less light is coming in) and so it will also take longer (*1024 sec or even a bit longer because of the reciprocity of film/sensor). Ambient light was already down: the curtains were closed in the bedroom . |

I think the other question before mine was what else do you need the 10 stop ND filter for. |

That is very hard to achieve. You need a 10-stop reduction. So doing this would imply that you go from f/8 @ ISO 100 to f/128@ ISO 25 and you are still halfway the road.

A 10ND stop filter is often used in industrial processes where lasers are involved. That light is very bright and using a 10 ND filter is making it possible to take photographs.
Another use is in seascapes: the sea is becoming all milky and creamy. |

I think you may have explained it in your last post; but the question was as specific as I thought it needed to be.
