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

It's quite simple. If the sculpture which you photographed is saved as a three dimentional image, it's still a sculpture, but in a digital format. However, if the photograph is two dimentional, it is only a picture. A three dimentional image of a sculpture that has been scanned/photographed can be printed in three dimentions just as well. Since the sculpture is 3D and is the input, the output must be in the format in order for it to be qualified as a sculpture.

The first answer reveals a possibility I had missed, as I took a "piece of sculpture" to mean a solid object that you made to light and photograph. The first answer proposes that you designed and "made" the sculpture on a computer and it never existed as a solid object and you either took screen captures or photos of the screen. As the second answer brings up, and I can't give names either, there are photographers that create incredibly complicated and fantastic scenes - buildings/rooms with distorted form, "nature" with fake beasts in it - and then photograph them to make very large high quality prints and then destroy the scene. Here is one http://jenniferzwick.com/work/photography/constructed-narrative/the-dream/ that I spotted by using Google Images to search for 'fantasy photography' You could make the sculpture and photo it and sell both - like Dale Chihuly sells the conceptual paintings he uses to create his glass works and the design sketches sold by the people who wrap islands and buildings with fabric.
