"Life in Stills," directed, produced and written by Tamar Tal, won the Best Film Award Tuesday in the Israeli Films Competition at the DocAviv International Documentary Film Festival. The prize carries an award of NIS 80,000.

The film depicts the emotional and complex relationship between Miriam Weissenstein-who together with her late husband, Rudi, founded the Pri-Or photography shop on Tel Aviv's Allenby Street 70 years earlier-and her grandson Ben, who takes over management of the mythological shop, even as it is slated for demolition.

"The story is told in a delicate, sensitive fashion, which succeeds in meshing a strong comic feeling with a powerful understanding of the times in which we live," the DocAviv judges said.

"With charm and wit, 'Life in Stills' creates a dialogue between the world of the past and today's world, and the unique relationship between the grandmother and her grandson captivated both us and the audience," judges said.

"Life in Stills" also won the prize for editing, which went to Tal Shefi.

The second prize of NIS 10,000 went to "The Collaborator and His Family," directed, produced and written by Ruthie Shatz and Adi Barash. For two years, the filmmakers followed the life of a former Palestinian informer for the Israeli security forces as he tried to hold his family together despite their difficult living conditions in Tel Aviv.

The film, recently shown in the prestigious Hot Docs international documentary festival in Toronto, also won the investigative reporting prize.

The films will be screened until the festival officially closes Saturday night.
