Like I said in my previous post, shooting at a game farm, or under controlled conditions is controversial. Some may look at it as "cheating", while others may view it as the ONLY opportunity they may ever have to photograph certain animals.
One thing to keep in mind though, when they are photographed under "controlled" conditions, you put a LOT LESS stress on the animal than you would if one were to STALK it in the wild, esp if it had young with it, and the animal would also be a lot more "nervous", and not as relaxed as it was if it was used to humans being around, and esp being photographed.
Yes it takes a lot more work to FIND the animal in the wild, and get a probably once in a lifetime photo of certain species, and it would definitely be more rewarding on a "I conquered nature" level, but if one wishes to increase their portfolio, then at least they have the option to photograph at a game farm, or a zoo.
Some of the top nature/wildlife photographers in the world, such as George Lepp, Joe McDonald, John Shaw, the Late Erwin & Peggy Bauer, Thomas Kitchin & Victoria Hurst etc all have photographed at game farms.
Again, it's a personal choice, there is no "right" or "wrong", I'm just saying that it's an option, and esp for "skittish" animals such as cougars etc, it allows them to be photographed without the stress that they would face if being stalked etc by a photographer in the wild.
Also, in the spring and early summer, most wolves, cougars, bobcat, lynx etc usually have their babies, and to have the opportunity to photograph the parents interacting with their babies is something that would be hard to forget.
But again, it's up to each individual person's own feelings, and needs.
