Cindy Sherman is an American photographer best known for her conceptual portraits involving self portraiture and ideas about feminism.
Her work generally relates to the feminine form and they way society and the media portray and view women.
The two images below come from a set of images that depict a variety of women in different emotional states from terrified to heartbroken. These pictures are both seductive but quite uncomfortable to look at, like a private moment is unfolding.
I think that the pictures show a raw emotion, and have a sense of unease for the viewer as they are not sure what moment has unfolded just before the photo has been taken to give the subject that facial expression.
I think facial expressions are important in portraiture as it is what the viewers eyes tend to go to first, and it can easily change the emotion behind the photograph.
