Brushes, and selections and masks in Photoshop, are more precise but tedious and time-consuming to learn and operate."},{"t":"p","x":"而Nik Viveza工具，由于使用了和手机Snapseed应用中一样的U-point控制点专利技术，可以实现既方便又准确的局部选区处理。","b":false,"xe":"Nik Viveza uses the same U-Point control point technology as the Snapseed mobile app, enabling local selections that are both convenient and accurate."},{"t":"img","f":"img-04","w":1000,"h":750},{"t":"p","x":"Nik Collection是谷歌公司旗下的一套后期插件集，包括了Color Efex Pro 4（调色滤镜集）、Silver Efex Pro 2（黑白胶片滤镜）、Dfine 2（降噪滤镜）等7款插件。今天我们讲到的Viveza 2只是功能丰富的Nik插件集中用于局部调整的滤镜。","b":false,"xe":"Nik Collection is a set of post-processing plugins from Google, including seven plugins such as Color Efex Pro 4 (color grading filters), Silver Efex Pro 2 (black-and-white film filters), and Dfine 2 (noise reduction).

If we only want to adjust a local area, we can click \"Add Control Point\" and then click a specific spot in the image to create a control point."},{"t":"p","x":"控制点中有一个影响范围滑块，可以控制影响范围的大小。控制点作用的区域，并不是圆形的，而是在这个圆形影响范围内，和控制点色彩、纹理、边缘比较类似的地方。","b":false,"xe":"Each control point has a range slider that controls its size. The area a control point affects is not actually a circle — it covers the places within that circular range whose color, texture, and edges are similar to the control point."},{"t":"p","x":"也就是Viveza工具，会根据控制点的中心和范围，智能的探测出我们要选择的物体。","b":false,"xe":"In other words, Viveza intelligently detects the object we want to select based on the control point's center and range."},{"t":"img","f":"img-07","w":1000,"h":592},{"t":"p","x":"在控制点列表中，我们点一下右边的勾，就可以显示出每个控制点作用的范围。显示效果和蒙版类似，白色是控制点完全影响的地方，黑色是完全不被作用，而灰色则是部分作用。","b":false,"xe":"In the control point list, clicking the checkmark on the right shows the area each control point affects. The display works like a mask: white is fully affected, black is completely unaffected, and gray is partially affected."},{"t":"p","x":"可以看到我们的第一个控制点，比较准确的选择到了中心的花朵，而且主要是花朵的红紫色部分。","b":false,"xe":"You can see our first control point selected the central flower quite accurately — mainly its red-purple parts."},{"t":"img","f":"img-08","w":1000,"h":567},{"t":"p","x":"不过花朵周边的一些物体，也受到了轻微的作用。很多时候这种作用可以让调整的边缘比较自然，有一个过渡。但是这个例子中，我只想调整中间的花朵，不想让其他地方受一点影响。","b":false,"xe":"However, some objects around the flower were also slightly affected. Often this makes adjustment edges more natural with a smooth transition. But in this example, I only want to adjust the central flower without affecting anything else at all."},{"t":"p","x":"这时我们可以通过添加其他控制点的方法让选择更精确。因为控制点的作用范围是互相排斥的，如果一个区域被控制点B控制，那么这个区域就会从控制点A中减去。所以我们在花朵旁边添加另外四个控制点之后，那4个控制点影响的区域就会从我们中心花朵的控制点中减去，从而实现了非常精确的选择。","b":false,"xe":"We can refine the selection by adding more control points. Control point ranges are mutually exclusive: if an area is claimed by control point B, it is subtracted from control point A. So after adding four more control points around the flower, the areas those four points claim are subtracted from the central flower's control point, giving a very precise selection."},{"t":"img","f":"img-09","w":1000,"h":600},{"t":"p","x":"每个控制点都有自己的作用区域，以及调整滑块。如果几个控制点作用的是同类物体（比如不同地方的荷叶），我们可以把这几个控制点分为一组，这个组控制的范围，是组内所有控制点范围的叠加。同时我们只需要调整一个滑块，就可以更新所有组内控制点的调整效果了。","b":false,"xe":"Each control point has its own affected area and adjustment sliders. If several control points target the same kind of object (for example, lotus leaves in different spots), we can group them. The group then covers the union of all its control points' ranges, and adjusting one slider updates the effect of every control point in the group."},{"t":"p","x":"分组有两个方法，一是在画面中拖动鼠标拉出一个矩形框，选择框中的所有控制点。或者可以按住command键（Windows系统为Ctrl键），在控制点列表中选择要分组的控制点。选择多个点之后，点击“分组”按钮，就可以把选择的控制点分为一组了。","b":false,"xe":"There are two ways to group control points. One is to drag a rectangle in the image to select all control points inside it. The other is to hold Command (Ctrl on Windows) and select points in the control point list. With multiple points selected, click the \"Group\" button to group them."},{"t":"img","f":"img-10","w":1000,"h":570},{"t":"p","x":"操作熟练后，我们可以很快的对复杂物体进行选取和调整。比如下面图片的天空，我们只需要两个控制点（分为了一组）就可以精确选择，然后对天空加蓝压暗。（注意看建筑的缝隙中露出来的天空，同样也被作用到了，选区非常的精准。）","b":false,"xe":"Once you're practiced, you can select and adjust complex objects very quickly. For the sky in the image below, we only need two control points (grouped together) to select it precisely, then add blue and darken it. (Notice that the sky visible through gaps in the buildings is also affected — the selection is extremely accurate.)"},{"t":"img","f":"img-11","w":1000,"h":585},{"t":"p","x":"如果上面天空的控制点，不小心影响到了其他物体，比如白云。我们只需要在白云上添加控制点，白云区域就会从天空控制点中被删掉了（谨记：控制点作用区域互相排斥）。同时我们可以给白云增加“细节强度”，让云彩的纹理和细节更加突出。","b":false,"xe":"If the sky control points accidentally affect other objects, such as white clouds, we simply add a control point on the clouds, and the cloud area is subtracted from the sky control points (remember: control point ranges are mutually exclusive). We can also raise \"Structure\" on the clouds to bring out their texture and detail."},{"t":"img","f":"img-12","w":1000,"h":569},{"t":"p","x":"像径向滤镜一样只需要建立几个控制点，却可以实现通道和蒙版般的精确选区调整，这就是Nik Viveza工具的强大之处。","b":false,"xe":"Requiring only a few control points like a radial filter, yet delivering channel-and-mask-level precision — that is the power of Nik Viveza."},{"t":"p","x":"本教程中的两张图片的raw文件，托马斯上传到了网上，大家可以下载：","b":false,"xe":"Thomas has uploaded the raw files of both images in this tutorial online for everyone to download:"},{"t":"p","x":"https://pan.baidu.com/s/1o7So0Ym","b":false,"xe":"https://pan.baidu.com/s/1o7So0Ym"},{"t":"p","x":"练习成果，欢迎发到微博并@Thomas看看世界 ，和大家一起分享讨论^_^","b":false,"xe":"You're welcome to post your practice results on Weibo and @Thomas Chu Photo to share and discuss with everyone ^_^"},{"t":"p","x":"欢迎关注@Thomas看看世界，","b":false,"xe":"Follow @Thomas Chu Photo,"},{"t":"p","x":"每个周日，学会一个摄影技能。","b":false,"xe":"and learn one photography skill every Sunday."},{"t":"img","f":"img-14","w":640,"h":313},{"t":"p","x":"如果您觉得文章有用，就把它分享给更多朋友吧^_^","b":false,"xe":"If you found this article useful, please share it with more friends ^_^"}],"titleEn":"Nik Viveza Guide: Local Adjustments Easier than Photoshop"}
