He was born in Saint Ottilien Convent, which was converted by USA occupation authorities to a soldier and refugee hospital after WWII.

Shirman got the first camera when he was 12 - a relative from America who visited Israel gave it to him and at the age of 15 purchased and set up a photo lab in the bathroom of the small house in Acre's neighborhoods.

From the beginning of his career, in the tradition of American photography and European photography, Shirman has been involved in his photographs with personal and collective biographical subjects related to the existence of Israeli land, history, memory, the Holocaust, family, Israeli army, portraits, changing landscapes and sea.

In dealing with the meaning and understanding of Holocaust memory and their impact on the present and future, on the existing and fictitious family albums and on the family itself, in the German, Polish and Israeli landscapes, Shirman tackles contemporary existential questions, the victim's image and the victim, the attitude toward, and the social-cultural, social- Guard towers and hunters - pastoral still life with threatening and threatening memory.

Acre, his childhood town, is the subject of his work, focusing on the Old City and its alleys, horses, old and new architecture, the Muslim cemetery and the sea.
