In Hamburg he began writing for Der Spiegel and Die Zeit, although his texts initially had to be translated. He worked for Amnesty in Los Angeles for some time, wrote for the Los Angeles Times and then traveled to Nicaragua as a freelance journalist, where he reported on the civil war there for various newspapers. There he also made his first documentary film With the Sandinistas (1978), which he shot in 16 mm format and sold to various television stations. After the end of the civil war in 1979, he moved back to Germany and took German citizenship in 1985.
From the 1980s Raman devoted himself increasingly to documentary film, acquiring the necessary knowledge autodidactically. To date Raman has made over 200 documentaries as a "one-man team". Since the 2000s he has concentrated primarily on war and crisis reporting for public broadcasting, traveling to Afghanistan, Somalia, Iraq, Syria, and other countries. In 2019, he announced that he would be withdrawing from war reporting because he was "tired of war" and suffering from health problems.
Raman lives in Selm in North Rhine-Westphalia. He is married and has two sons.[4]
