Dijkstra's photos mostly pertain to portraits and she shoots in color. Her beach series was very interesting because she had her subjects stand in fron the sea and it was just them and nature. The poses were awkward but that was her point, to show the human's form and vulnerablity. she neatly arranges her subject against the sea and sky and their expressions are very uncomfortable. I read in this book specifically on this photo that the women is posing similar to Botticelli's Venus emerging from the foam. I agree and her expression seems like this is new to her and she doesn't know what to do with herself.
