霉变黑白照相物证底片的图像恢复方法
An Image Restoration Method for Mildewed Black-and-white Forensic Photographic Negatives
摘要
Abstract
Before the widespread use of digital photography technology,photographic negatives captured on photosensitive film served as crucial evidence in solving old and unresolved cases,providing important information for the successful resolution of cases.However,early black-and-white evidence negatives,taken during case proceedings,were prone to severe mold damage due to factors such as storage conditions,leading to blurred prints and significantly impeding the extraction of forensic details.This paper introduces a restoration method for severely mold-damaged negatives,which involves using a high-boiling-point liquid material with diisooctyl phenyl phosphite(DPOP)as its main component.Applying this material to the surface of the moldy negatives fills in the roughness caused by mold and eliminates the diffuse reflection of visible light caused by mold spots,effectively restoring the image quality on the damaged negatives.Meanwhile,the method is reversible.Once a clear and complete image is obtained,the applied restoration material can be removed,allowing the negative to revert to its original state and ensuring the integrity of the evidence.Employing this method,we successfully recovered the image on an evidence negative from a serious criminal case,fully reproducing the forensic information recorded on the film over 30 years ago and establishing a solid foundation for the case's successful resolution.关键词
