Many friends still aren't clear: what exactly is ACR? Why does Thomas say that learning ACR means learning Lightroom editing? And what's the difference between ACR and Lightroom?"},{"t":"p","x":"今天托马斯就跟大家一一详细解答。","b":false,"xe":"Today Thomas answers these questions in detail, one by one."},{"t":"p","x":"知识点：ACR、Lightroom、Photoshop","b":false,"xe":"Topics: ACR, Lightroom, Photoshop"},{"t":"p","x":"阅读本文需要约5分钟","b":false,"xe":"Reading time: about 5 minutes"},{"t":"h","x":"1","xe":"1"},{"t":"h","x":"ACR究竟是什么？怎么打开？","xe":"What exactly is ACR? How do you open it?"},{"t":"p","x":"ACR的英文全称是Adobe Camera Raw，也就是Adobe公司旗下的照片Raw文件处理器。Photoshop软件中都附带有ACR，安装了PS，自动就安装了ACR。","b":false,"xe":"ACR stands for Adobe Camera Raw — Adobe's RAW file processor. Photoshop ships with ACR included, so installing PS automatically installs ACR."},{"t":"p","x":"Raw文件又叫数字底片，是数码相机所生成的原始格式文件，能比JPEG格式储存更多的信息。几乎每个相机厂商都有自己的Raw文件格式，常见的Raw文件后缀包括.NEF, .DNG, .CR2等等。","b":false,"xe":"RAW files, also called digital negatives, are the original format files generated by digital cameras and store far more information than JPEG. Nearly every camera maker has its own RAW format; common extensions include .NEF, .DNG, .CR2 and so on."},{"t":"p","x":"正因为各家厂商的Raw格式各不相同，所以Photoshop本身是无法直接识别这些千奇百怪的Raw格式的，需要通过ACR处理器先解析转换一遍。同时ACR还提供了很多调整选项，这些在Raw文件之上的调整都是完全无损的，也就是底片信息并没有被覆盖，随时可以一键复原。","b":false,"xe":"Precisely because each maker's RAW format differs, Photoshop itself cannot directly recognize these varied formats — they must first be parsed and converted by ACR. ACR also provides many adjustment options, all completely non-destructive on top of the RAW file: the negative data is never overwritten and can be reset with one click at any time."},{"t":"img","f":"img-02","w":640,"h":400},{"t":"p","x":"打开ACR非常的简单，一般有两种方法。","b":false,"xe":"Opening ACR is very simple; there are generally two ways."},{"t":"p","x":"只要我们安装了Photoshop软件，双击打开Raw格式文件（比如尼康的.NEF格式），自动就会弹出ACR调整面板。","b":false,"xe":"With Photoshop installed, just double-click a RAW file (e.g. Nikon's .NEF) and the ACR adjustment panel pops up automatically."},{"t":"img","f":"img-03","w":640,"h":462},{"t":"p","x":"如果我们还安装了Adobe Bridge等相机管理软件，我们也可以在Bridge中鼠标右键照片，选择“在Camera Raw中打开”。","b":false,"xe":"If you also have camera-management software like Adobe Bridge installed, you can right-click a photo in Bridge and choose 'Open in Camera Raw'."},{"t":"img","f":"img-04","w":640,"h":430},{"t":"p","x":"无论哪种打开方式，Raw文件都会在ACR软件中打开，可以进行各种各样的无损调节了。","b":false,"xe":"Either way, the RAW file opens in ACR, ready for all kinds of non-destructive adjustments."},{"t":"img","f":"img-05","w":640,"h":400},{"t":"p","x":"Raw文件在ACR中处理结束后，可以有3种方式保存：","b":false,"xe":"After processing a RAW file in ACR, there are 3 ways to save:"},{"t":"p","x":"1） 点击ACR右下角的“完成”，点击之后你的处理步骤会以额外的.xmp文件格式纪录在硬盘中。下次再打开这张照片的时候，这些xmp中保存的处理结果也会被一并导入。","b":false,"xe":"1) Click 'Done' at ACR's bottom right — your processing steps are recorded on disk in an additional .xmp file. Next time you open this photo, the saved results in the .xmp are imported along with it."},{"t":"p","x":"2）点击ACR右下角的“打开对象”，点击之后你的处理步骤会以额外的.xmp文件格式纪录在硬盘中。同时ACR会把处理后的Raw转换成Photoshop能理解的格式，在Photoshop中打开，这样我们就可以在PS中做进一步的处理了。","b":false,"xe":"2) Click 'Open Object' at ACR's bottom right — your steps are likewise recorded in an .xmp file, and ACR converts the processed RAW into a format Photoshop understands and opens it there, so you can continue in PS."},{"t":"p","x":"3）点击ACR左下角的“储存图像”，可以把照片输出成 .JPEG 等常用的图像格式。","b":false,"xe":"3) Click 'Save Image' at ACR's bottom left to output the photo to common formats like .JPEG."},{"t":"img","f":"img-06","w":640,"h":417},{"t":"h","x":"2","xe":"2"},{"t":"h","x":"ACR和Lightroom有什么不同？","xe":"What's the difference between ACR and Lightroom?"},{"t":"p","x":"Lightroom是Adobe公司旗下的一款图像管理和处理软件。","b":false,"xe":"Lightroom is an image management and processing application from Adobe."},{"t":"p","x":"读完上面的介绍可能你已经发现了一个不同，那就是Lightroom除了可以处理Raw文件，还有非常强大的管理功能。Lightroom为摄影师提供了一种全流程的解决方案，包括图库管理，修改照片，打印输出等等。","b":false,"xe":"After reading the above you may have spotted one difference: besides processing RAW files, Lightroom has very powerful management features. Lightroom offers photographers a full workflow solution, including library management, photo editing, print output and more."},{"t":"p","x":"其中Lightroom中的修改照片面板，和ACR几乎是一模一样的。所以Lightroom其实就是在ACR的修改功能基础上，还包括了额外的功能。","b":false,"xe":"Lightroom's Develop panel is almost identical to ACR. So Lightroom is essentially ACR's editing functionality plus additional features."},{"t":"img","f":"img-07","w":640,"h":335},{"t":"p","x":"ACR是以文件为基础的，所以打开Raw格式直接在文件夹里双击文件就可以了。而Lightroom为了管理照片，有一个“中央目录”纪录着所有照片的标记和修改信息，所以要在Lightroom中处理照片，有一个额外的“导入照片”步骤。","b":false,"xe":"ACR is file-based, so opening a RAW file is as simple as double-clicking it in a folder. Lightroom, to manage photos, keeps a 'central catalog' recording all photos' tags and edits — so working in Lightroom requires an extra 'import photos' step."},{"t":"img","f":"img-08","w":640,"h":324},{"t":"p","x":"在修改照片的部分，Lightroom虽然和ACR几乎一模一样，但是还有一些其他有用的功能。","b":false,"xe":"In the editing part, although Lightroom is nearly identical to ACR, it has some other useful features."},{"t":"p","x":"比如Lightroom的“预设”可以保存一张照片的处理参数，把同样的风格应用于其它照片中。虽然ACR中也有预设功能，但是网上流传的各种“大师调色预设”都是Lightroom预设，这点Lightroom完胜ACR。","b":false,"xe":"For example, Lightroom 'Presets' can save a photo's processing parameters and apply the same style to other photos. ACR also has presets, but the various 'master grading presets' circulating online are all Lightroom presets — Lightroom wins hands down here."},{"t":"p","x":"还有一个Lightroom中有但ACR中没有的功能，就是“历史纪录”。你在Lightroom中的每一步调整都记录在了历史记录中，随时可以回到以前的任一状态。","b":false,"xe":"Another feature Lightroom has but ACR lacks is 'History'. Every adjustment you make in Lightroom is recorded, and you can return to any previous state at any time."},{"t":"img","f":"img-09","w":640,"h":341},{"t":"p","x":"什么？Lightroom竟然比ACR强大这么多，那么为什么还要用ACR呢？","b":false,"xe":"What? Lightroom is that much more powerful than ACR — so why use ACR at all?"},{"t":"h","x":"3","xe":"3"},{"t":"h","x":"ACR的优势","xe":"ACR's advantages"},{"t":"p","x":"ACR的一大优势就是方便好用，有的时候我们并不需要对大量照片进行管理和批处理，我们只想安安静静的精修一两张照片而已。这个时候ACR就方便多了。","b":false,"xe":"One big advantage of ACR is convenience. Sometimes we don't need to manage and batch-process large numbers of photos — we just want to quietly perfect one or two. That's where ACR is much handier."},{"t":"p","x":"更重要的是ACR学习简单容易上手，一旦学会ACR也就学会了Lightroom的修改面板。所以初学者可以先从ACR学起，熟练之后再掌握Lightroom中的额外功能，循序渐进。","b":false,"xe":"More importantly, ACR is simple and easy to learn — once you've learned ACR, you've learned Lightroom's Develop panel. So beginners can start with ACR and, once proficient, master Lightroom's extra features step by step."},{"t":"p","x":"ACR中的照片修改功能和Lightroom中的修改选项几乎是一样的，只是布局上有所不同。ACR中的基本调整、曲线、锐化降噪、镜头校正等功能，以面板的形式展现。","b":false,"xe":"ACR's editing functions are almost the same as Lightroom's — only the layout differs. In ACR, basic adjustments, curves, sharpening/noise reduction, lens corrections and so on are presented as panels."},{"t":"img","f":"img-10","w":640,"h":513},{"t":"p","x":"在Lightroom中，基本、曲线、镜头校正等，以下拉菜单的形式出现。","b":false,"xe":"In Lightroom, Basic, Curves, Lens Corrections and others appear as dropdown sections."},{"t":"img","f":"img-11","w":640,"h":540},{"t":"p","x":"ACR中强大的裁剪、污点去除、画笔、渐变滤镜、径向滤镜等功能，在软件最上面的一排图标中。","b":false,"xe":"ACR's powerful crop, spot removal, brush, graduated filter and radial filter functions sit in the row of icons at the very top of the software."},{"t":"img","f":"img-12","w":640,"h":395},{"t":"p","x":"Lightroom差不多，这些功能也在直方图下面的一排图标中。","b":false,"xe":"Lightroom is similar — these functions are in the row of icons below the histogram."},{"t":"img","f":"img-13","w":640,"h":484},{"t":"p","x":"总而言之，学会了ACR修图，我们也就学会了Lightroom修图。","b":false,"xe":"In short, once you've learned ACR editing, you've learned Lightroom editing."},{"t":"h","x":"总结","xe":"Summary"},{"t":"quote","x":"1.
