After two decades covering the violence of the first and second uprisings against the Israeli occupation (in 1987-1994 and 2000-2005), Silwadi's life took a dramatic turn in 2006 when he was hit by a stray bullet fired by Palestinian gunmen.
Silwadi, 33 at the time, was in his office in the West Bank city of Ramallah when he heard gunmen outside firing during a funeral procession.
"I heard shooting in the street and I ran to the window to take pictures," he recalls, describing how a group of gunmen were firing into the air as a show of mourning.
He spent 40 days in a coma and when he woke up, a doctor told him he would never walk again.

Eight years on, Silwadi, now 40 and a father of three girls, is still in a wheelchair.
He remains hopeful that one day he will walk again, but he has not let his disability get in the way of his passion for photography.
"I'm working even better than before my accident," he says.
"Being so close to dying and then hovering between life and death for such a long period of time left me far more spiritual and has helped me see life differently, to see that it is beautiful," Silwadi says.
After his convalescence, he immediately began working on the painstaking task of setting up the Palestinians' first-ever digital archive, collecting pictures and video clips of the life and work of Yasser Arafat, the iconic Palestinian leader who died in 2004.
His meticulous work earned him a job with the UN cultural agency UNESCO as an expert consultant on digital archiving.
He then turned his attention to his own photo archive, publishing a collection of images called "Palestine, How Are You?" featuring pictures of daily life as seen through the eyes of a child.
