We must not take the people to be real, but we must link with them all the feelings and associations which we would connect with real men.

This is possible only if in their flat, colorless, pictorial setting they share the real features of men.
For this reason it is important to suggest to the spectator the impression of natural size.

The demand of the imagination for the normal size of the persons and things in the picture is so strong that it easily and constantly overcomes great enlargements or reductions.

We see at first a man in his normal size and then by a close-up an excessive enlargement of his head.

Yet we do not feel it as if the person himself were enlarged.
