Corina's Shiner

Corina is the proud owner of her first shiner - she climbed into a card board box and was playing around, when she attempted to get out it fell over and her face hit the corner of a chair. It quickly turned black and blue. In this picture it's somewhat hard to tell how big of an area that was brusied, that's where converting it into a negative image can somewhat help (a negative image is a tonal inversion of a positive image, in which light areas appear dark and vice versa). You can see a splotch on the cheek of the negative which is the bruised area.
