If you make a piece of sculpture to photograph it, is it no longer a sculpture?

Suppose I made a piece of sculpture that looks amazing, but let’s also suppose that what I really wanted to do was to photograph it and create some interesting compositions with my photos, not really to display the sculpture (although it CAN be displayed). Does the work no longer become a sculpture but a photograph? And saying they are both is too easy of a way out of it. I’m really looking for some serious answers.
