'Nemai Ghosh: A Ray of Light' is a moving story of how an ordinary man came to be associated with a giant of cinema-Satyajit Ray-and became the photo-chronicler of his creative and personal world. It also pays tribute to the elegance of black-and-white films and the nuances of analogue photography. The cinematography has been specifically designed to reflect Chiaroscuro-the blending of light and shade which both Ray and Ghosh admired and followed in the footsteps of Henri Cartier-Bresson. This is the story of an inspiring friendship, of the pursuit of artistic excellence and of a journey that started fifty years ago.
