I used one pack and felt the novelty wore off after the first couple of shots. Really depends on the subject. If 'creative' and 'different' is what you want from this type of film, then maybe produce with different animal heads, or mix up the location of the ape head on the film itself. If honest, it did not really compliment what would otherwise have been a couple of delightful shots. Yet, had I know the outcome I would have chosen a subject such as clouds, or something with a little more natural drama
