25 fotos espectaculares da criação de um bebé!

Durante 12 anos o fotografo sueco Lennart Nilsson tirou fotografias ao desenvolvimento fetal dentro do útero.

Estas imagens são espectaculares e foram tiradas com câmaras convencionais equipadas com lentes macro, e inseridas através de endoscopia e utilizou também um microscópio para detectar electrões.
Nilsson aumentou milhares e milhares de centenas de vezes e o resultado foi este. 
A sua primeira fotografia de um feto foi tirada em 1695.
