I recently entered the ASMP LA photo contest that had the theme "Margins" interpret it anyway you want. Whenever I have the opportunity to push the boundaries with subjects (and involve food) I like to jump at the idea. For this series of images I interpreted the word margins as the mouth. We use it everyday and really it has its own boundaries or "margins."
I thought it would be interesting to play with the edges of the mouth while someone was eating. I would photograph their movements of chewing and carefully selecting food that could create a mess or fall outside the edge of the mouth. There are a couple from the series on my conceptual portfolio and more at my APA gallery.
