Floating peacefully inside its mother, a tiny fetus flexes its fingers and sucks its thumb. Breathing amniotic fluid into its lungs, it makes a strange, hypnotic sound. Now, the photographer who led us into this awe-inspiring world of the womb has agreed to take us behind the scenes of his own work. For the first time ever, Lennart Nilsson reveals the state-of-the-art techniques that gave us The Miracle of Life and so much more. How does he capture the exact moment of conception? How does he (without special effects) turn a beetle into a menacing dinosaur- while rendering "tiny" humans in super-sharp focus as well? How does he convince a famous opera star to solo for him- with an endoscopic camera in her mouth? "I know where that little camera has been," the reluctant singer quips. For decades, this unparalleled photographer has astonished the world with images- from the creatures under the sea to the viruses inside our cells- that make visible the mysteries of life. Yet Lennart Nilsson has kept his own secrets to himself... until now.
