Software tools used: Photoshop 7 and Neat Image Pro Version 2.5 with plugin Skill level: Beginner to intermediate [B]Step[/B] 1 Start by making a duplicate of your image as you should NEVER work on the original. Also, you will be using the original as a comparison basis. *All references to Photoshop menus will follow the format - MENU - Menu item - Submenu item *MENU - Image - Duplicate Arrange the images similar to Example 1 (below) with the duped image on the right

加积分：3 理由：转贴教程 操作：fx [B]Step[/B] 2 Select the duped image MENU - Select Color Range The Color Range dialog window will pop up. Move the window similar to Example 2 (below) so that you can see the duped image. At this point, you want to select a skin color range that will encompass most of the skin. You do so by placing the cursor on the image to the right and clicking on a medium skin tone. The Fuzziness option selects pixels by controlling the degree to which related colors are included in the selection.

The purpose hereis not exactness, but to get a decent selection of overall skin tones. Inaddition, you can use the eyedropper + (Example 3 A) to add colors and the eyedropper - (Example 3 B) to take away colors. Notice that there is a little bit of hair selected as well. Don\'t worry, we\'ll take care of that next. Click OK in the color range window to make the selection.

[B]Step[/B] 3 You will now have made a selection of skin tones with the Color Range tool. There should be an outline (marching ants) around the areas that are selected. (Example 4) Notice that the marching ants selection corresponds directly to the light areas of the Color Range dialog window. (Example 5)

[B]Step[/B] 4 We want to smooth out the selection to make it easier to work with so use: MENU - Select - Modify - Smooth Use a value of 4 (4 is just a baseline and not an only use number) Notice that the selection outline (marching ants-Example 6) has smoothed out compared to Example 4 above.

[B]Step[/B] 4 At this point there are numerous avenues available to us as we now have a selection made. Photoshop has extreme power in the manipulation of selections but for the sake of simplicity we\'re going to use a simple method. Press the Q key. This puts you into Quick Mask mode. The light areas correspond directly to your original Color Range selection (Example 6). In a nutshell, the dark red areas are unselected image pixels, and the light areas are selected image pixels.

[B]Step[/B] 7 Press the Q key again to exit Quick Mask mode. You will now see a nice marching ants outline of the areas you cleaned up in the Quick Mask mode. ( Example 9) Notice that the selection outlines correspond exactly with the Quick Mask that we made on the right. (Example 10)

[B]Step[/B] 5 Press the D key. This resets your foreground and background colors to black and white respectively. Select the brush tool (B) and then select a soft edged round brush of around 35 pixels. You will use this brush to fine tune your mask. Painting with black adds red and painting with white erases red. In the example above (Example 7) I want to fill in the areas of the hair so I paint with black over the hair area that is light. I then paint in all non-skin areas with black. [B]Step[/B] 6 Now, there are some areas of the face and arms that need to be expanded . These areas have red over them. In the example above you will notice the excess red around the eyes, chin, neck and right cheek. Pressing the X key will now select white for your brush. The X key toggles between your foreground and background colors. We used the D key earlier to reset the foreground and background to black and white. With the same brush using white as the color, we now paint around the eyes, chin, neck and right cheek. The example below (Example 8) shows how the finished mask will look for this tutorial. Remember, you don\'t have to be perfectly exact in your outlining and if you take away too much red you can add it back with the black brush and vice versa with the white brush. The purpose here is to make a general skin mask.

[B]Step[/B] 8 At this point if you are not quite happy with your selection outline, just press Q again and follow [B]Step[/B]s 5 and 6 until you are satisfied. For the purpose of this tutorial, we are going to continue with the above selection as it looks fairly even. Press Ctrl-J and this will copy the selection to a new layer. Your layers palette will look similar to Example 11 below. Notice that the new layer, Layer 1, contains only the selection we made and nothing else. Example 12 ( below) shows what the layer will look like if we turn off the background layer below it by click the eyeball beside the Background layer. You may notice that a bit of hair made it into the selection. We can just use the eraser brush to get rid of the excess hair at this time.

[B]Step[/B] 9 So now all we have to do is run the *Neat Image plugin on this new layer ( Layer 1) and there you have it, perfect, creamy smooth skin. The settings that you make inside the NI plugin will determine how much smoothing is applied to the layer. Just remember that it won\'t hurt to be on the aggressive side with the amount of noise reduction because you can dial down the effect using the opacity slider. *The use of Neat Image settings, profiles and parameters will be discussed in a separate tutorial. [B]Step[/B] 10 And here we have the before and after example. Notice that the Neat Image filter only affected our masked area and left the rest of the image as is. There are endless possibilities with this type of technique. For those of you familiar with selections and layer masks, you have an almost unlimited ability to fine tune that look you are after. Of course, the methods shown here can be applied to general noise removal as well. I use multiple selections to isolate different areas and types of noise, then apply varying NI settings to achieve the ultimate in noise control. Hope this tutorial made some sense and that you can get some use from it. Here\'s a simple synopsis of what we did: Duplicate the original first and always Select our skin tones with Select Color Range Use the Quick Mask to refine our selection Make this selection a new layer with Ctrl-J Apply the Neat Image filter Some tips on making the selection: Select only skin areas, not eyelashes, eyebrows, etc. You can feather the selection at any time using MENU - Select - Feather. Use a small radius of 2 or so to blend in nicely. You can expand or contract the selection as well from the MENU - Select - Modify submenu. Regards,

这种磨皮技术，我早就在用啦^_^不错啊！不过不知道有多少人能够全懂

[B]ADJUST[/B]

能不能大致翻译一些重点操作，方便E文不是很好的人。

看不懂~~

说实话..偶也常常有看没有懂啦..不过看图说故事 [fly]按图施工+保证成功[/fly] -- [move]试试看呗[/move]

不用完全翻译，只需要重点步骤就行了。

重点步骤，先试试吧！不过 Neat Image Pro Version 2.5 这个东东我没有啊！ 大致说一下啦！

[此贴子已经被作者于2003-8-2 18:37:31编辑过]

我只说ps部分的吧，不过没有这个滤镜，我从他的教程中想到另一种办法[em01]

加积分：5 理由：另创思路 操作：fx 以此图为例吧[upload=jpg]UploadFile/20038218405589213.jpg[/upload] 这个转贴的精华部分是在磨皮后人物的皮肤不会失去质感，不会像 3D的作品。真实感极强的^_^开始咯！ 第一部选择皮肤调整颜色容差使噪点显露出来如图所示1所示！[upload=jpg]UploadFile/20038218415875837.jpg[/upload] 下面就是应用添加取样和减少取样来使噪点显现^_^手工活啊！zhangshiqi要注重练习的效果如图啦[upload=jpg]UploadFile/20038218425192504.jpg[/upload]

先声明以下这个就不是原来的啦[em01] 下面的操作很简单，不用其它的就ps就能完成这个是我得到的选区无法上传啦！ 干讲吧！就是把噪点选出来在背景层进行去噪，应用ps自带滤镜去除杂点！然后新建图层一将选区复制到图层一应用蒙尘与划痕来处理改图层，图层样式为滤色！合并两图层完工 这样可以避免单独的使用蒙尘与划痕来处理图像使图像的亮度大幅提升！ 这是我的想法^_^不是原教程的！

能够加上你磨好的效果会更好。 ------------------------------------------------------------------ 下面是我用DigitalCameraTools做的效果，主要还是觉得比较简单，适合于喜欢简单的朋友。若你对画面追求不是很细腻，就可以试用这个：) 这里，这位漂亮MM脸上的情况比较好，只需载入cleanskin fx里简单处理即可： [upload=jpg]UploadFile/20038222593766664.jpg[/upload] 而后： [upload=jpg]UploadFile/20038223012667809.jpg[/upload] 此时MM脸上还有少数区域有偏色，执行替换颜色： [upload=jpg]UploadFile/20038223034116062.jpg[/upload] 用吸管工具在色彩有问题的地方点击，再用带加号的吸管增加选区，调整参数如下： [upload=jpg]UploadFile/20038223052916765.jpg[/upload] 现在我对面部的颜色还是不太满意，所以再执行一次替换颜色： [upload=jpg]UploadFile/20038223072599545.jpg[/upload] 最终效果： [upload=jpg]UploadFile/20038223083634168.jpg[/upload] 最终效果是一种蒙胧美，要简单，就行。
