The excuse that this was hard work by the photographer is interesting but does not hold up. Yes it is cold in the Himalayas, but when you have a large team of assistants to assist you and you are being paid to stay there then that is your choice, do not claim this as skill. How many of us could set up 14 IR triggered cameras (even if they were cheap models) and come up with such average images after 10 months speaks for luck rather than skill. Locally to me we have a research group studying Leopard called Cape Leopard Trust, they are doing very worthwhile research into an elusive animal and have "captured" many good images but I would not conceive that prior to now any would have considered they should be entered in a photographic competition

At least nobody here has said it is a rare picture, of an endangered animal, there are in fact considerably more Snow Leopards than Tigers it is just that they are in areas where not many people go. Just google Snow Leopard, I do not think the judges did they just believed what they were told.
