The audience should close their eyes while the first group gets into position. When the group has its first image ready, the designated person says ‘Open’. The audience open their eyes for a few moments and look at the scene. Now the same person says ‘Close’ and the audience close their eyes again. Quickly, the group moves into the second position and the audience are asked to open their eyes when the group is ready. The process is repeated until all the still images have been shown. The technique has a similar effect to watching a series of photographs or a flickering film.
This technique is great fun and can be surprisingly effective.
