easy steps on writing on images in the truman show, state what the image is of, state techniques used in the image, what the technique does, then link it to the idea which it is attempting to put forward to the responder.
for an example, aerial shot of truman driving around the round-a-bout screaming "im being spontaneous" which in reality this is not true as his whole life is being controlled as this shows the power of the media and illusion and reality.
