| The graduation work tries to use the creation technique of observation mode to focus on the marginalized group of autism.presenting their real family life and social communication,so as to arouse the attention and reflection of the public.Combined with the author’s thinking on the theory of observational model documentary,this paper interprets the aesthetic construction of the graduation work dear child from the aspects of narrative form,image style and spatial metaphor of observational model documentary."Marginal theme" corresponds to the construction of theme..Autism patients suffer from many social problems faced by marginalized groups,and inevitably lose their main identity in social discourse,lose their right to speak,and cause identity anxiety."Observational mode" corresponds to documentary technique and aesthetic norm.The documentary of observation mode requires the photographer to only observe,without any obvious intervention,and pursue the ideal "truth".Its aesthetic standard is to observe the truth,only presenting without comment,only observing without explanation,and achieving image disillusion. |
