Tutorial Fog Tutorials

Migrator's note: Uokiok is the original author.

This simple little tutorial is the use of multiple layers of overlapping PS, atmospheric effects mimic nature. We all know that in reality, no matter how good regardless of the weather, because the distant landscape changes in atmospheric concentrations will produce the same effect as some of the fog. Although the fog effect, but not obvious, so here in XL using Photoshop in a simple simulation.
这个简单的小教程是利用PS进行多层重叠，模仿大自然的大气效果。我们都知道在现实中不论天气再好，远处的景物都会因为大气浓度的变化而产生一些雾气一样的效果。在XL中虽然有雾的效果，但是不够明显，所以在这里使用Photoshop进行简单模拟。

Step 1
Prospects first need to observe the picture, a landscape photograph distinction, medium shot and vision
步骤一
首先需要对图片进行观察，区分出一个风景照片的前景、中景和远景

Similarly, in the foreground and then roughly distinguish foreground, middle ground and vision. Feel a sense of depth.
同样的在前景中再大致区分前景、中景和远景。感觉出层次感。

Step 2
1 Create a new layer, fill to white and set the opacity to 50 or 80%. 2 Use the lasso tool or pen tool check prospects parts removed.
步骤二
1.新建一个图层，填充成白色并且设置不透明度为50~80%。2.使用套索工具或者钢笔工具勾选前景部分，删除。

Step 3
Duplicate the layer one, the use of copy out of the new layer. Use the Lasso tool to select medium shot partially removed. Note adjust the opacity observation. Each layer are behind the implementation of this method of operation until the farthest vision.
步骤三
复制图层一，利用复制出来的新图层。使用套索工具选取中景部分删除。注意调整不透明度进行观察。后面的各个图层都执行这个操作方法，直到最远的远景。

Finally, adjust the opacity of all layers were observed.
最后调整所有图层的不透明度进行观察。

Step4
Ctrl + left mouse button to select the layers one by one, in the background layer little Gaussian blur processing. Each layer of a constituency, and then do it again in the background layer Gaussian blur. In other words, as far as the vision for eight times.
步骤四
Ctrl+鼠标左键逐个选取图层，在背景层进行很少的高斯模糊处理。每一层一个选区，然后在背景层再做一次高斯模糊。也就是说，最远的远景做了8次。
