This effect was generated using a fe methods firstly i added a new adjustment layer (Hue/Saturation) then i reduced the saturation of the image to 0% causing the image to become black & white. Following this i then went on to erase this adjustment layer above areas such as the mouth and the eyes, so that the colour comes through. Following this i then went on to use the magnetic lasso tool to elongate the teeth of the model to appear as fangs. I then went on to erase the background of the image in order to ensure that the model is the focal point of the image.
