The ninth "Image China" national photography art exhibition has disqualified 27 out of 52 awards in the documentary category, Beijing Youth Daily reported Friday.

About 70-80 percent of the 27 disqualified images had been modified in Photoshop, an expert who attended the appraisal meeting said.

"The documentary images must be real, and the altered photos must be disqualified," said Bai Suoliang, a photographer in Shanxi province, "I hope the organizers and the judges can put a solution on the table."
