I find that it is very useful to look over the location and to feel out the atmosphere while waiting for the actors. It may happen that the images before my eyes coincide with those I had in my mind, but this is not frequently the case. It more often happens that there is something insincere or artificial about the image one has thought of. Here again is another way of improvising.
