camera density calculations

individual bucks /  buck photos = population factor

extrapoaltion factor = 1 / percentage photographed based on day

bucks = indivudal number x extraptilation factor

does = photos x populatin factor x extrapolation factor

fawns = photos x populatin factor x extrapolation factor
