Photo Realistic Face Texturing

First of all, you will need a set of images from the different angles that you want to blend together (Fig.00).

首先，你得有一套从不同角度拍摄的（同一个人的）人脸图片。这些图片是混合操作的源文件。（如下图）

Go to File > Automate > Photomerge (Fig.01)

打开PS，选择文件 – 自动化 – 图片拼接（下图，下同）

Make sure you select the interactive layout option so that you can position your images properly. Click Browse and select the images you would like to use (Fig.02).

记得选“互动版面”这个选项，这样你才能正确地摆放照片。点击“浏览”并选择你想用的图片。

The top bar will have thumbnails of your selected images which you can drag onto your work area. You might want to unclick Snap to Image over on the right side. Try to position the images by lining up key details such as the corners of the eyes and mouth. You may need to open the images separately and use the Transform deformation tool to tweak the images to line up a bit more prior to your importing them into Photomerge. Once you’re satisfied with the alignment, click OK. You can also save the composition in case it needs to be reloaded for further adjustments (Fig.03).

你可以从对话框上部的缩略图栏里拖动图片到下方的工作区。你可以把右方“对齐图像”这个选项关掉。调整图片位置，尽量让关键部分——比如眼角和嘴角——排成一条直线。在导入到“图片拼接”之前，你或许还需要分别对每一张照片进行变形微调，让关键部分更好地排成直线。在排好位置之后，点击“确定”。你也可以保存合成数据，以备未来之用。

If all goes well – voila! – you should have something similar to this and you can now use any brush to adjust your blending on the mask. Each piece will have its own layer and can be adjusted separately (Fig.04).

如果一切顺利，好，一切完成！你应该得到与下图差不多的结果。现在你可以用任何笔刷来调整你的合成结果。每一片“拼图”都在独立的层里，可以对它们分别调整。

Now you can adjust your UVW to match this, or use Photoshop’s Transform deformation lattice or liquify to fit this to your UVW pretty quickly.

现在你可以根据这张图设置UV权重了，或者你可以用晶格变形、液化等工具快速调整合成图，使之更好贴合UV权重。

I hope this has been of some help!
