    Here's a clip of shot Canopus not sure of the date but I'm assuming it is the shot from 24/08/1968. This is colour footage, and is different than the two clips on this site.

    always a document from stupid TV journalist....

    Not canopus !

    - First shot (at night) = aldebaran, july 1966
    - second shot= encelade* shot

    * encelade & licorne shot were often mistaken (vice-versa)

    One question:

    Seens to be night when the bomb explodes.
    After the explosion the sky become clear and we see that is day,not night.
    Why this happens? Question

    The initial fire ball is several hundred times brighter than the sun. The camera (or more specifically the film) is unable to cope the difference in luminosity between the fire ball and the surroundings. As the intensity of the light decreases, the camera is able to perceive the other objects in the frame. The latitude (range of exposure) possible for most film stocks is too narrow to get proper exposure over the entire range of light levels produced during the detonation.

    The effect is the inverse of photographing someone standing with the sun behind them, the person will be a silhouette.

    "Probable the biggest challenge was what kind of exposure do you use? But really whatever exposure you used, you're gonna be okay, because the light intensity goes way up and it gradually diminishes. So, whatever you're exposure is it's gonna be okay because somewhere in there it's gonna be correct."
