A Child is Born

  Incredible Photos: A Child is Born

Swedesh photographer Lennart Nilsson spent 12 years of his life taking pictures of the foetus
developing in the womb. These incredible photographs were taken with conventional cameras
with macro lenses, an endoscope and scanning electron microscope. Nilsson used a
magnification of hund reds of thousands and worked right in the womb. His first photo of the
human foetus was taken in 1965.
