Is Seeing-In a Transparency Effect?

Philosophers of art use the term 'seeing-in' to describe an important part of our experience of pictures: we often 'see' a picture's subject matter 'in' its surface. This paper proposes that seeing-in is illuminated by a perceptual phenomenon that has received extensive attention in perceptual psychology: the perception of transparency. It is generally accepted that transparency perception is governed by laws of 'scission'. I argue that some instances of seeing-in can be straightforwardly understood as a kind of transparency effect, and that all seeing-in is illuminated by these laws.
