The death of Olivier Voisin, 35, comes a year after fellow Frenchman Rémi Ochlik was killed in Syria alongside Sunday Times journalist Marie Colvin.
Voisin is reported to have suffered serious head and arm injuries from an exploding shell in the northern city of Idlib on 21 February. He died three days later in a Turkish hospital.
Christophe Deloire, secretary-general of press freedom body Reporters Without Borders, said the photographer's death highlights the ‘heavy price being paid by those covering Syria's armed conflict'.
He added: ‘I pay tribute to the 23 journalists and 54 citizen journalists who have lost their lives in Syria since the start of the uprising in March 2011.'
