• ⁨Comment⁩ on ⁨Im watching an episode of Mr. Rogers Neighborhood, filmed in black and white. In this scene a guest is showing glass making. What is going on with the film to make these black areas by the flame?⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  If this was filmed in the late sixties using an older orthicon camera it might be an artifact of the way that the image is produced.

  I’m just going from memory, but I believe the tubes used a brightness-amplifying screen kept charged with electrons that, when struck by light, would result in a brighter image that could be scanned by a beam. The downside of this technique is that a very bright area would suck up electrons from around it resulting in a dark halo.

  I think I remember some of the oldest classic Doctor Who episodes has this visual artifact, as well as some old Beatles TV recordings.
