利用Photoshop CS处理强反光圆柱体上的手印照片

Getting Desired Fingerprint Images on Heavy Reflective Cylinder Using Photoshop CS

现场勘查中常遇到圆柱体反光表面客体,如防盗金属门窗上的圆管等,因受光面不均匀,容易产生强烈的反光带,拍摄这类客体上的手印痕迹较为棘手,为了有效地获得这类物证,在充分运用近距离照相技术获取手印的数码照片后,再利用Photoshop的图像调整功能,对图像的色调、色相进行合理的调整,会得到良好的图像效果。

Reflection on cylinder surface, such as tubes on metal security gates, is very commonly encountered during field investigations. The uneven reflection surface in turn easily produces heavy reflective belt, which makes the shooting of fingerprints on the surface of such subjects extremely difficult. To obtain good material evidence, pictures can be taken using Close Range Shooting technology, based on which images can be adjusted in Photoshop CS. Image color and hue then can be properly adjusted in the software for desired effects.
