Importance of art direction

Set dressing and costume helps to create the mood in the film. For   a cinematographer also  set dressing and costume is very important.  What we see through the eye of lens is the performance of the actor and there surrounding/environment which can either bring the audience in or out of the movie.

The colour what we place in the set and the choose of colour for the costume can help to set the tone and the feeling to the particular scene.
