As Barthes says “What found the nature of photography is the pose. The physical duration of this pose is of little consequence even in the interval of a millionth of a second there has still been a pose” Camera Lucida pg 78. And this pose will remain forever not like cinema, movie that the pose is gone.
The pipe in the picture has only one pose and meaning and never changes, but the pipe in the movie has it own meaning and it changes its characteristic during duration of the movie although they might have the same concept.
The photograph express itself as a silent moment just one decisive moment but movie is not a silent moment, contents with a period of time, which time is the measure of continuance of any object or event. The photographs will be one frame but the movie has more than a frame so it makes it more real to human eyes when they play back to back, which makes it more dimensional than just photographs.
