The Fujifilm Finepix X10 (FX10) camera has an EXR sensor. This provides a hardware method of expanding dynamic range which is not explained or even mentioned in the owner's manual.
富士X10有一只EXR图形芯片。这提供了硬件动态范围扩展。这以前没有被提到过。
This article is designed to help FX10 owners understand how their EXR system works and how to get best performance from the camera, using the EXR sensor's unique capabilities. The observations and suggesttions which follow are based on my own tests of an FX10 over the last two weeks, involving many hundreds of systematic test exposures.
这个主题主要是帮助X10玩家懂得EXR系统怎么工作，以及怎么用EXR获得最好的效果。
以下都经过本人（老外）测试
Point and shoot photographers will manage very nicely with the following settings:
大部分情况下，使用如下设置可以获得好片
Set EXR on the Mode Dial and EXR Auto in the Shooting Menu. Just point and shoot. The camera will make a multitude of calculations on the run and deliver a good result most of the time. JPG files only.
大部分情况下，将模式盘拨到EXR模式，可以获得画质良好的JPG图片。
For better image quality and more control over the image capture process, expert and enthusiast photographers will want to use RAW capture. My comparison studies have shown that in the majority of cases a well processed RAW file delivers better Image Quality (IQ) than JPG, even using the tedious Silkypix.
为了获得更好的图像质量，和更好的控制图片，需要用RAW模式拍摄。我的比较研究已经发现，大部分情况下RAW可以比JPG可以获得更好的图像质量。
Suggested Settings for RAW capture: Note: These settings apply when RAW+JPG is set in the Setup Menu. If RAW only is set, a different range of options for Image Size and DR is evoked.
RAW建议设置：注意：这些设置仅在RAW+JPG模式下有效。如果仅RAW出片，那么就会是不同的出片尺寸范围和DR范围选择了。
On the Mode Dial set P,A,S or M. In the Shooting Menu, Set Auto ISO (limit 3200), Image Size M (=6MPx), Dynamic Range DR400%, Film Simulation Standard, AF Mode Area. In the Setup Menu, Set Fn button to ISO, IS Mode 2 Shooting only, RAW + JPG.
在P,A,S,M档下。在惨淡中，设置自动ISO（限制3200），图片尺寸M，动态范围扩展DR400，胶片模式标准，AF模式。
在设置菜单中，设置Fn功能按钮为ISO，IS模式2拍摄（不懂），RAW+JPG。
Now to explain why: Everything from here assumes RAW + JPG capture.
现在解释为什么：这里的一切都需要RAW+JPG模式。
The internal workings of the FX10 using L (=12MPx) Image Size are fundamentally different from those which operate using M (=6MPx). The difference is much more than just image size.
使用X10 拍摄L（12M尺寸）和M（6M尺寸）是不同的，远远不紧紧在于图片尺寸。
There are two separate and distinct systems for Dynamic Range expansion in the FX10. The Owner's Manual fails to mention this but awareness of the difference is the key to understanding how the camera works.
有两套独立的系统在X10上可以进行动态范围扩展。玩家的机器菜单没有提及到这些，但是玩家意识到了这些不同来理解X10是怎么工作的。
The first system is DR expansion in software and is the same as that used on many digital cameras from many makers. Basically it underexposes the scene to protect the highlights then applies a tone correction curve in camera to lift the mid and dark tones. On the FX10 it works in L Image Size. If you set DR400% the minimum ISO permissible is 400. The camera will force ISO 400 even if you set 100.
第一套系统是DR扩展（软件），这用在很多机器上。基本理论就是让芯片降低曝光来保证高光细节。在X10上，这工作在L尺寸。如果你设置DR400，即使你ISO设置100，也会工作在ISO400下。
（这部分专业性太强，翻译不好。参考EXR工作原理）
The second is DR expansion in hardware and is the unique function of the EXR sensor. This will not work using L image size, it requires M image size. ( 6MPx) It operates at any ISO ( but not at slow shutter speeds) The pixels on the sensor operate in adjacent pairs. One pixel gets the full exposure time, while the adjacent one gets a fraction of that time, controlled on chip. Some very clever proprietary Fuji technology combines the two exposures into a single image with higher dynamic range than is possible at ISO 100 using the full 12 MPx. The same process also delivers lower noise at high ISO than is possible using the full 12MPx.
第二套系统是DR扩展（硬件）。这是唯EXR芯片才有的功能。这不能工作在L尺寸。它需要M尺寸。它工作再任何ISO下（慢速快门下无效）。传感器上的像素成对工作。一个像素完全曝光，另外一个减少曝光，工作在集成电路上。一些很聪明的富士技术将两曝光合成为一张图，这样比使用L尺寸有更高的动态扩展范围。这种处理办法同时会得到更低的噪点在高ISO情况下，相比L尺寸。

My comments on issues arising:
我的测试：
My tests show that 6MPx delivers resolution only marginally less than 12MPx. In fact in some situations 6MPx does better than 12. For instance if using L image size and DR100% produces blown highlights (and it often will) then highlight definition is actually improved by going to M size and DR400. Another example: On a bright sunny day if you set L image size and DR400, the camera will force ISO 400, and in consequence an aperture of f8 or f9 because the shutter runs out of fast speeds. The optimal lens aperture for the FX10 is about f4, so the higher ISO and smaller f stop both degrade resolution to the point you would have been better off using M image size in the first place with ISO 100, DR400 and f4. In addition the FX10 lens is a bit soft in the corners wide open and the extent to which this reduces resolution is minimised by using M image size.
我的测试表明，6M图片仅比12M的图片稍微差一点点。实际上，一些情况下，6M图片可以比12M图片做的更好。比如，如果用L尺寸，DR100，低光照，那么高光配置下可以将尺寸调整至M尺寸，DR400，可以获得更好的效果。
另外一个例子：阳光普照，如果你设置L尺寸，DR400，相机将强制ISO400，并且光圈会收至F8或者F9，因为工作在更快的快门。X10的最佳光圈在F4，所以更高的ISO和更小的光圈都会削弱画质如果在第一种环境下不使用M尺寸，ISO100，DR400，F4。
另外，X10的镜头有点软如果广角全开，通过使用M尺寸可以讲此降至最低程度。

Auto ISO: The FX10 seems to set the optimum combination of ISO, shutter speed and aperture most of the time so Auto ISO works well for most situations.
自动ISO：X10自动ISO优化的非常好，大部分情况下自动ISO都工作的非常好
I think that DR 200 is not worth bothering about. DR 800, 1600 are only available in EXR Mode, DRange Priority, JPG.
我认为，DR200不值得忧虑。DR800,1600只在EXR模式，DR扩展，JPG模式可以用。
The takeaway message: I found very few if any situations where the FX10 delivered better image quality at L image size than M image size. So I use and recommend the settings given above all the time in all situations. Doing so gives reliably good results and certainly simplifies using the camera.
总结：我并没有发现在很多情况下L尺寸比M尺寸效果更好。所以我使用如上提到的设置拍摄。这可以提供可接受的图质，并且更简单的使用相机。
Good luck with your own tests and do enjoy using the clever Fuji X10 camera.

Author's declaration: I am a private, amateur camera user. I have no sponsor and no connection with any maker or vendor of photographic equipment. I bought my Fuji X10 at normal retail price in Australia. I really like figuring out how stuff works and the FX10 was a nice challenge.

这个贴没人顶的么。。。

X系列本来就小众人少，还要从为数不多的机器持有人中筛选出懂蚯蚓文的，再从其中的其中挑出有耐心读一大篇文字的有心人，难免曲高和寡

顶顶了，虽然看不懂。

失误 失误

我晚上回去翻译下

翻译的丑不要怪

这篇文说 EXR 很强

顶顶了，虽然看不懂。

翻译的很烂，大家见谅了。

顶顶了，虽然不大会用EXR 。

LZ辛苦了
如果有X10，很值得尝试一下。

X-pro1没有EXR吗？不会吧。

我比较粗心，没注意过。

这种帖子一向都是superEBC的专利啊
对了，superEBC最近哪去了？

翻了翻说明书，没有看见EXR的字样。看看机器，也没有发现。
百度上说：
“一种新的CCD感光器件
原理
　　已用于数码相机，由于红绿蓝三种像元采用特殊方式排列
效果
　　使数码相机具有感光动态范围宽的特点。”

在 《太平洋数码》的网页的介绍，好像是有EXR的。
S100也有EXR，使用情况和楼主介绍的差不多。如果设置了EXR400，ISO自动成400了，而且不用EXR了，ISO也不调回来了。这对小CCD的机器来说，图像质量大打折扣的。我用小CCD的机器的最大教训就是千万不用高ISO。
