With a backpack carrying a Canon camera and a laptop strapped to his back, adman Gopal MS sets off every day, traversing through cramped lanes of Mumbai, absorbing and documenting the city's assorted moods. As he takes us behind his lens, a photograph of a group stuck knee-deep in an almost black Mithi River catches the eye. The brain does an immediate recall of the stench stemming from the neglected river as it passes through Khar, Bandra and Mahim.

It's this brain-eye-nose reflex that Gopal's latest digital photobook titled, Matsyagandha, hopes to cash in on. Set for a self-published online release next month, this is the fourth book from Gopal's — the adman who runs the MumbaiPaused twitter handle — stable.
