      We have used this style a couple of times in the office and I am a big fan of it. It is also really simple to implement. The idea is to apply a mask over a full resolution illustration to break up the edges giving the illustration a collage-like feel. The great thing about this technique is that while you are getting a less formal collage style, the image still has all of its information, detail, and resolution where it counts.
      I have chosen two new views of my wharf design to show how it works. The mask is best applied at the very end which means a full illustration edge to edge is still necessary. This also means if the mask isn't working, it is no big deal and can be removed without any harm to the illustration.
      Below is the full frame base rendering before masking (desaturated to better show the masking).
   我们公司用了好几次这种风格的图片，我挺喜欢的，而且实施起来也很简单。制图思路就是在高清图片上附加一个蒙版来打破图片边界，从而制造出一种“拼贴感”。这样做的好处在于，你的图片有了一种不那么死板的拼贴风格，同时图片保留了全部要表达的信息、细节和分辨率这些有价值的部分。

我选择了我的船坞设计的两张新视图来做演示。蒙版最好是最后再加，意思就是说一张边界完整的图片还是必要的。而且即使蒙版的效果不尽如人意也没关系，直接去掉蒙版对原图也不会有任何破坏。

下面是一张在做蒙版之前边框完整的基础渲染。（为了更好地演示蒙版，图像做了降低饱和度的处理）

The blue represents what I masked off. The mask was made by creating a new layer and moving it to the top of the other layers. I then selected the "Polygonal Tool" and began selecting areas that I wanted to mask. Once the selection was made, I filled in the selection with a white paint. I went through many of iterations testing out what areas should be masked and what works best compositionally. I experimented with softening the edges or lowering the opacity, however, I ultimately preferred the crisp edges and the sharp contrast between the white and rendered areas.

蓝色的地方就是我遮盖的部分。如何创建这一蒙版呢？首先建立新图层，将其挪至所有图层的最上层。然后选择“多边形选择工具”开始选取我想要遮盖的部分，选好后在选区内填充白色。我反复试验过哪些地方需要遮盖以及一些组合效果。我尝试过柔滑边缘或者降低透明度，不过最终我还是比较喜欢这种硬朗的边界和白色与渲染图之间的锐利对比。

It is a simple move, but one that completely changes the tone of the image.

这是一步简单的操作，但整个图片的调子一下就不一样了。

The final illustrations were rendered with V-Ray at a resolution of 4500px X 2500px. I then tweaked colors, textures, and added people in Photoshop. Finally, I jumped into my Topaz Labs PS plugin to punch up the detail.

最终的渲染使用的V-ray，分辨率4500px X 2500px.然后我调整了颜色、材质，p上了人物。最后我转至TOPAZ LABS PS PLUGIN （一个ps插件？→见网站）http://www.topazlabs.com/adjust 来进一步加工细节。
