| 摘 要： | 在刑事案件的现场拍照和物证检验照相中,经常会遇到一些遗留在平面强反光物体上的反差微弱的疑难指纹,拍摄难度很大。采用二漫法来加强这类指纹痕迹与承受载体之间的亮度差,显露指纹,简便易行,效果良好。应用二漫法拍照要求选用适宜的照相器材,掌握正确的操作方法,方可获得良好的拍摄效果,改善指纹痕迹的检验条件。

| Abstract: | When taking photos in the spot of a criminal case or for checking object evidences,it is very difficult to shoot the suspicious fingerprints with minor differences left on the surface of objects with strong reflective light.Under such a circumstance,it is effective to adopt the method of double reflection,to deepen the shade of light between the fingerprints and its carrier so as to reveal the fingerprints more clearly for an easy discovery.Therefore,we should imply the proper photographic instruments according to the requirements of double reflection of random rays,master correct operating methods so as to obtain satisfactory shooting effects and improve the conditions for checking fingerprints. |
