I'm going to pose a situation and hope it generates some good feedback.
Recently on the Digital Photography Review forum a/k/a DPR there was considerable discussion about a well-known photo contest in the U.K. It seems there was a category for wild animals. The rules specified the animal pictured must not be captive. The winning entry was a wolf jumping over a fence. Other entrants complained claiming the wolf shown was a trained animal and the picture a set-up. After much investigation the judges finally disqualified the picture and photographer even though he staunchly claimed the picture met the rules.
Now, in our case, suppose we have a contest. Lets say for turned bowls. A winner is picked for #1. Later, another entrant complains saying the winner really bought the bowl at a show. But the winner says he turned it.
What to do?
My take. The final product, picture or bowl should stand on it's own. There is, and was, virtually no way to prove the wolf was, or was not, captive. Besides, what is 'captive'? Does it live in a cage? Or an enclosed five acre grounds? Or, maybe it lives on a 10,000, completely fenced game ranch. Is that 'enclosed'?
Or, who is to say who made the bowl?
