佳能友研究课题！

我发现几乎所有的佳能照片都有“曝光模式：未记录”，let's solve this problem!

看来顺手解决了此问题！请指教！

    你是指在公摄显示还是在自己电脑里看？公摄的参数显示功能也可能不是很完善。

rpan

公摄显示,但为什么顺手的无敌兔工作？

Stone

公摄显示的不全。

这是你的EXIF， 可能Exposure Program没设？

I will double check the original photo info before I upload to "GongShe". Thanks!!!

rpan

Got， in Canon， it is called "shooting mode", but in 公摄显示, it is called "Exposure Program", that is XML tag issue. So, in 大头的parser that should use both tags "shooting mode" and "Exposure Program".

moonbay

看来只要大头把程序稍加修改即可。

    我不顺手谁顺手啊。。。。。。。。。
我也没刻意显示什么，它就顺手显示了，可能我这名字比较lucky吧

这好像没有解释为什么你的没有显示，而顺手的有显示，你们俩的可都是无敌兔。。。

回复 10# Stone


    请顺手查一下你的无敌兔firmware version? 我们的都是2.0.7。再有，查一下你的language 是？English 或中文？最后当你编辑图时，用文件菜单，信息，看你的模式用的是“shooting mode" 或“exposure program"? 你用的是什么编辑工具？先谢谢了。

    一下子布置了这么多作业 我还得做一下研究。。。。

到那里查firmware version？language当前设的是中文，也可设英文，有信息输出有区别吗？
其他的我还得顺手查查在回答你吧，现在困了 要迷糊去了

澳洲大头

你们先调查，调查清楚了我再看程序。。。。。

rpan

回复 12# 顺手


    Firmware可以在相机的菜单上看到。不过，已经弄清楚了！你用了中文，所以，照片的附加XML信息和大头的程序兼容。Canon凡是机器用英文的，当上载照片时，XML都不能兼容大头的程序。这样只能请大头兄在你的程序产生曝光模式时，同时接受Canon 的"shooting mode" and "Exposure Program"tags.
麻烦你了！！

hmm. i use the 40D, shoot manual but it doesn't show either.

Not that it's important.. as long as we see the aperture value and shutter speed, its sufficient right?
