The picture department was small, with limited resources, and it was made clear to him from the outset that he would be worked hard. At 34 and versatile and energetic, he soon proved his worth and within 6 months the Picture Editor wrote to him to say : 'Before I leave the news-room this morning, I want to congratulate you. Seldom if ever can any photographer have had so many pictures published through all the editions of one Sunday’s ‘Observer’. Never, to the best of my knowledge, has anyone achieved such a high standard over so wide a range of subjects – news, business, feature and sport, in a single issue of the paper. Thank you for working so willingly and so well.'
He told fellow Observer photographer, Bryn Campbell, in the British Journal of Photography in 1967, when he was 37 : “There is a part of me that would like to go away and take photographs 24 hours a day, live and eat photography, work myself into a lather and imagine I’m a sort of a Van Gogh, but the other half says you have got to earn a living.”
These were the years in which he captured :
'Abandoned cars. Walworth Road. 1966'
'Street Fighting in Glasgow'
David returned to street photography, with Sonya, after an absence of over 40 years in 2013, when he was 76. In his spare time he documented the street life around Brick Lane in Tower Hamlets, East London, which today, it is the heart of the City's Bangladeshi-Sylheti community and is known to some as Banglatown. The result is a testimony to his talent as a photographer who captured the exuberance of multicultural street life in Britain today, just as he had done as a young photographer on the streets of a largely monocultural Glasgow and London in the 1960s.
