When photographing paper and card, you are able to cut, tear and shape the individual pieces to create abstract effects when taking photos. As seen below:
This enables a clear definition between the lights and darks to the photo, whilst it being very simplistic at heart, the scrunched effect makes an almost complicated look to the image.
This allows us to experiment as a photographer with not only composition but in a way our artistic creativity as well, due to how we are able to warp the materials given to form structures which we are able to use to our advantage.
