ExifTool：强大的图像文件信息查看程序
Posted on 08 Nov 2014 PhotoTools 添加评论
ExifTool真是强大到手软，不管是你想查看图片里的源信息，还是想程序处理照片，ExifTool绝对提供了足够丰富的信息和方便的接口。ExifTool还有Perl的函数库接口，真是强大无极限啊！
ExifTool支持Canon, Casio, FLIR, FujiFilm, GE, HP, JVC/Victor, Kodak, Leaf, Minolta/Konica-Minolta, Nikon, Nintendo, Olympus/Epson, Panasonic/Leica, Pentax/Asahi, Phase One, Reconyx, Ricoh, Samsung, Sanyo, Sigma/Foveon and Sony诸多品牌的RAW文件，能提取包括不限于 EXIF, GPS, IPTC, XMP, JFIF, GeoTIFF, ICC Profile, Photoshop IRB, FlashPix, AFCP and ID3的多种信息。ExifTool同时支持Window，Linux和Mac OS X操作系统，也有很多已经开发好的图形界面，比如上面的截图就是其中之一ExifGUI。
同时，由于ExifTool的简单设计，她也有很多其他语言的接口包，包括而不限于C++，AppleScript，C#，VB，.NET，PHP，Python，Rupy，Java等等。对于需要将Exif信息用于自己程序的人ExifTool提供足够优秀的接口。
另外对于使用Lightroom处理图像的用户，ExifTool也有相应的Lightroom下的插件，在此仅推荐一个叫做ExifMeta Lightroom Plugin。 ExifMeta同时又Windows和Mac OSX的版本，可以整合到Lightroom中使用。下面是一个官网上插件的截图：
最后，上一个照片的ExifTool输出的某张照片的信息，可以看到信息相当丰富，甚至包括了相机和镜头的序列号。
