1.1本指南概述了使用反射光显微镜拍摄金属和材料时可能遵循的各种建议方法。包括使用直接快速和湿法制备黑白和彩色印刷品和透明胶片的方法。 1.2必要时提供描述性材料，以澄清程序。在详细描述可能有帮助的地方引用了参考文献。建议使用指南生成典型受试者的显微照片，并尽可能生成非典型受试者的显微照片。包括有关增强显示特定材料特征的技术的信息。 1.3本标准无意解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全和健康实践，并确定监管限制的适用性。具体预防说明见附录X1.7。 1.4各节按以下顺序出现: 内容章节放大率4显微照片的复制5光学系统6光源7试样的照明8聚焦9显微照片的滤镜10照明技术11摄影材料12摄影曝光13摄影处理14金相显微镜的视觉使用建议X1金相显微照片的指南X2视频图像打印X3

1.1 This guide outlines various suggested methods which may be followed in the photography of metals and materials with the reflected-light microscope. Methods are included for preparation of prints and transparencies in black-and-white and in color, using both direct rapid and wet processes. 1.2 Descriptive material is provided where necessary to clarify procedures. References are cited where detailed descriptions may be helpful. Guidelines are suggested to yield photomicrographs of typical subjects and, to the extent possible, of atypical subjects as well. Information is included concerning techniques for the enhanced display of specific material features. 1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Appendix X1.7. 1.4 The sections appear in the following order: Contents Section Magnification 4 Reproduction of photomicrographs 5 Optical systems 6 Illumination sources 7 Illumination of specimens 8 Focusing 9 Filters for photomicrography 10 Illumination techniques 11 Photographic materials 12 Photographic exposure 13 Photographic processing 14 Suggestions for visual use of metallographic microscopes X1 Guide for metallographic photomacrography X2 Video image printing X3
