“In a nutshell and to prevent my english readers from experiencing eye bleeding after having read too many syntax errors, I’m a french journalist – I work as an editor, not as photographer – who happens to be nuts about photography.

Reuters photographer Bobby Yip took a series of portraits of people taking part in the “Occupy Central” protests in Hong Kong, and asked them why they had joined the demonstrations.
