From where I stand,apart from being used to represent our experience of the world and reflecting the relation between producers,the viewers and the object represented,the image have the capacity 

to form texts or complexes of signs.Now,let begin my analyse of the poster about a kind of make-up.

     First of all,let talk about the analyse of representational meaning.The image depicts an action for the reason that the beautiful lady in the image holds the rose and gazes at us.

   It's turn to the choice of interactive meaning.Aiming to demand us to get close to the charming lady represented in the image , she not only  gazes at the viewers,but also represented from a eye level.   In addition,she is represented from a front angle and by a medium shot.

    Last but not least,in terms of the analyse of composition,the elements in the image placed along   the horizontal axis.The make-up at left is described as given,while the attrative woman at right is       described as new.Consequently,the producers want to put the fact that if we use their make-up,we     will be as beautiful as the lady in our minds.

    In short, the purposes of the producers are attract our attentions and want us to purchase their      products
