this is the work of Margareth Doorduin. Doordium plays strongly with the absence of the subject . they are there but we cannot see their eyes or their facial expression. the only clues she gives us to find them is their body language and the elements in their environment. beautifully played! check out more here
the work of William Hundley. The series "Entoptic Phenomena" uses floating fabrics as its subjects. the result is quite intriguing as every photo tells a different story about urban life and interaction.
