The initial concept of film as film remains unchanged, but the interest or point of attack has shifted, from the levels of mechanism and materiality of the medium, to the psychological and psychophysical level, where meaning and affection - in other words the mental processes of the image - play a major role. To this is added an approach based on a totalizing, synthetic and eclectic notion of the image and no longer according to an analytical and reductionist approach. According to this new approach, any image is made up of several elements which are heterogeneous or even contradictory.
