I have found that people on the street do not like having their photograph taken for one reason or another, there can also be at times ethical and legal issues with street photography.
Obscuring the faces on purpose is an attempt to adapt to take into account these issues.
This has also led to questioning what abstract photography is. Abstract photography in a way cannot exist because with any photograph one takes, one is always capturing a reality. With this series of images, I have photographed people who are behind old, worn see-through plastic (often bus shelters and phone booths) and in doing so have reduced them to colours and shapes. Yet I have still captured a fleeting reality. I like this dichotomy.
