一片关于ND和IRND的测试文章，求大神翻译

chrisziling

以前卖了国产的ND偏色十分厉害，最近纠结重新买个ND，但是不知道到底用什么好，搜到一篇测试的文章，原文是《IR ND Filtration + EPIC》貌似很专业，并提供R3D文件下载，无奈英文太差，谷歌机器翻译后仍然不是很理解，恳求大神翻译结论！！
Conclusions:
- For those of you who are picky like me, play it safe and use IR filtration whenever using ND.

- For those of you who are less picky, you can feel comfortable not using IR filtration up to 0.9 ND. You WILL need it at 1.2 ND and above.

- No matter what brand of ND's you choose go with ONE brand so that the color shift is the same throughout the range of filtration. You want, and need to keep things consistent.

- White balance AFTER the ND has been put in the camera. This is a MUST on non-raw cameras, and post workflows, and it is HIGHLY recommended even on raw cameras as it will help communicate your intent, as well as make sure that any rushes or dailies that are produced look correct. Always remember and repeat this montra: "Fix it in camera, NOT in post."

- The new Schneider Platinum IRND's are doing a great job at keeping the IR pollution out of the image while producing nice blacks. At the stronger levels, some refinement will still be needed as there is a slight shift towards blue. But it is more then manageable, and preferable to the brown Formatt + TruColor.

- The Formatt + TruColor combo, while it worked on the Red One, doesn't seem to be holding up as well with the Epic. Personally, I wouldn't use it past 0.9 ND, but if you are less picky about your blacks actually being black, then you might find the 1.2 ND & 1.5 ND to be acceptable. The 1.8 ND combo is completely unacceptable to me.


I hope you have found this helpful as you consider ND filtration for your latest generation digital camera. Now I need to do the same with a daylight balanced source ...

另外再请教下： 白平衡 Meter 和 Post 分别是什么档位？

Conclusions:

结论

- For those of you who are picky like me, play it safe and use IR filtration whenever using ND.

对我那些和我一样吹毛求疵的货，当用到ND的时候，稳妥的选择使用红外滤镜

- For those of you who are less picky, you can feel comfortable not using IR filtration up to 0.9 ND. You WILL need it at 1.2 ND and above.

而对于那些要求不太苛刻的人来说，不超过0.9的IRND是还是可用的，一般情况下1.2以上的ND会好些


- No matter what brand of ND's you choose go with ONE brand so that the color shift is the same throughout the range of filtration. You want, and need to keep things consistent.

无论用什么牌子的ND，最好保持品牌的一致性，这样一来偏色也可以保持相对的一致，这是你获得一致画面的前提

- White balance AFTER the ND has been put in the camera. This is a MUST on non-raw cameras, and post workflows, and it is HIGHLY recommended even on raw cameras as it will help communicate your intent, as well as make sure that any rushes or dailies that are produced look correct. Always remember and repeat this montra: "Fix it in camera, NOT in post."

装上ND以后再调白平衡，这对于非RAW机器是必须的，而对于后期流程来说，强烈建议使用RAW格式的摄影机进行拍摄，这更有利于达到你的预期，同时也可以保证预览和样片显示正确。永远记住一句话：在摄影机就把一切调好，不要在后期中再进行补救。

- The new Schneider Platinum IRND's are doing a great job at keeping the IR pollution out of the image while producing nice blacks. At the stronger levels, some refinement will still be needed as there is a slight shift towards blue. But it is more then manageable, and preferable to the brown Formatt + TruColor.

新的Schneider Platinum IRND表现不错，可以很好地消除红外干扰而得到漂亮的黑色，不过对于更高的要求来说，稍许偏蓝的问题还是需要进行一些改进的。不过这点问题比起褐色的Formatt + TruColor已经很牛逼了。

- The Formatt + TruColor combo, while it worked on the Red One, doesn't seem to be holding up as well with the Epic. Personally, I wouldn't use it past 0.9 ND, but if you are less picky about your blacks actually being black, then you might find the 1.2 ND & 1.5 ND to be acceptable. The 1.8 ND combo is completely unacceptable to me.

当在Red One上使用Formatt + TruColor的时候，似乎并不像Epic一样能够hold住，个人而言，我不会用超过0.9以上的ND，但如果你对于黑色是不是还是纯黑这个问题没这么事儿逼的话，1.2ND和1.5ND还是可以接受的。1.8 ND对于我来说已然完全不能够了~

希望在你为你的数码摄影机选择ND的时候会有所帮助，我去死了~有事烧纸~

他这个meter指的是color meter（色温表），应该是在机内直接调节白平衡后的结果，post是机内没调，后期调整后的结果，主要是为了说明，对于非raw一定别在后期调，要在机内就调好，而raw挽救偏色的余地要大些，但依然建议在机内就设置好，这在他结论里有讲
