警察学院毕 业 论 文 弱光条件下的现场照相年 级 2024 级 姓 名 王 江 平 专 业刑事科学技 术 指导老师 田 德 林 2024 年 5 月 27 日摘 要 本文是对弱光条件下现场照相的技巧进行的探究。文章创新性地利用照度和照相曝光原理分别对弱光照明作了定义，通过对弱光现场照相概念的理解，进一步对弱光现场照相的分类、照相方法、拍照原则和步骤进行了阐述。明确了弱光现场照相对于刑事侦查的重要意义，弱光是现场照相影响照片质量的主要因素。根据现场照相的容，进行了弱光现场方位照相、弱光现场概貌照相、弱光现场重点部位照相和弱光现场细目照相四个方面的实验。通过理论和对实验数据的分析，得出了弱光条件下的现场照相技巧，为刑事现场照相技术人员记录和固定弱光现场物证提供理论依据和实践参考。关键词 弱光 现场照相 照度 Low light photography of the siteAbstractThis site is under low light photography skills to the inquiry. Article innovative use of principles of illumination and camera exposure low light illumination, respectively, are defined by the concept of the understanding of low-light camera site, and further classification of low-light field camera, photographic methods, principles and steps to take photographs are described. Clear low-light field camera for the importance of criminal investigation, low-light camera site main factors affect the photo quality. According to the contents of the scene camera, was low-light camera site location, low-light camera site profile, low light and low-light camera site key parts of the scene breakdown of the four experimental photography. Through theoretical analysis and experimental data obtained under low light conditions, the scene camera techniques, camera-site technical staff for the criminal records and fixed-site exhibits low light provide a theoretical basis and practical reference.Key words ：low-light；Live camera；Illumination目 录引 言....................................................
