Oh yes, that I saw, and I've used it myself. It's very helpful. But the point I was making was that it's easier to take clear, crisp, detailed photos of a disease condition when the fish is dead and out of the water, than it is a live fish. It seems that fish aren't very cooperative when it comes to being photographed, especially when it's some small spot or patch that you'd like to be able to get a clear photo of to aid in helping others help you make a diagnosis.
