具体的制作步骤如下：

Step 1: Creating a New Document第一步：创建一个新文档
 

We are going to create a new document with a standard resolution of 256px. But because our icon is quite short the height will be smaller.
我们将创建一个256像素标准分辨率的新文档.不过我们的图标高度稍微小一点。
Next, grab the Paint Bucket Tool (G), and fill the document with the following colour #F2F2F2. This is to make viewing easier.
然后，使用油漆桶工具(G)，使用#F2F2F2颜色填充文档。这是为了查看更轻松。
Step 2: Setting The Base第二步：设定基础
 

Using the Ellipse Tool (U), draw an oval on a new layer as shown above. Let’s name this “Top”.
使用椭圆工具(U)在新层上画一个类似上图的椭圆，取名“TOP”。
 

Shape layersUsing the Shape layers instead of Fill pixels allows you to transform your circle as many times as you want without quality loss. This is great for experimenting.
形状图层
使用形状图层替代填充像素可以让你任意变换你的形状而没有画质损耗。这是非常值得的尝试。

Step 3: Going 3D第三步：创建3D效果

 

_ueditor_page_break_tag_
 

Select your Move Tool (V). While holding down the alt key, press the down arrow 20 times. This will determine the height of the icon. Now select the past duplicates and Merge (ctrl+E). Arrange that layer below the “Top” layer. Remember that there should be one extra layer named “Top”. We’ll just name this new merged layer “3D” for readability.

选择移动工具(V)，按着Alt键，按下箭头键20次。这会让图标有高度的感觉。现在选择刚才所有的复制品层，然后选择融合(Ctrl+E)。将这个层放到”Top”层下面。这里会有多个层都叫“Top”，为了区分我们将新融合的层命名为“3D”。
Step 4: Layer Styles第四步：图层样式
Now we are going to apply some Layer Styles to the “Top” layer (the non-3D one). You can do this by double clicking on the layer.
现在我们要给“Top”层(没有“3D”的那个)添加一些层样式。你可以双击层打开窗口。
 

You should end up with this:

最后结果应该类似这样：

Step 5: 3D Layer Styles第五步：3D图层样式
Now select the “3D” layer and apply the following Layer Styles.
现在选择“3D”图层然后添加如下的层样式
 

Once you are done you should have this:
这次完成后应该是这个样子：
 

Step 6: Creating The Shadow第六步：创建阴影
Create a new layer below the previous two layers and name it “Shadow”. Get the selection of the“Top”layer by ctrl+clicking on the layer icon. Fill the selection with Black and Deselect (ctrl+D) it. Go toFilters>Blur>Gaussian Blur and use 5px. Set the Opacity to 75%. Using the Move Tool (V), shift the shadow down just below the body of the icon.
新建一个层在之前两层下面并命名为“Shadow”。在“Top”层图标上按照Ctrl键点击框选该层。用黑色填充并取消选择(Ctrl+D)。然后选择滤镜–>模糊–>高斯模糊，半径为5px。设置透明度为75%，然后使用移动工具(V)将阴影移动到图标主体的下面。
 

Step 7: Adding Polish第七步：添加光线修饰
Create new layer right at the top. Get a White Brush with a Hardness of 0% and Master Diameter of 125px. Get the selection of the “3D” layer and Brush once at the corner. Set the Opacity to 85%.
在最上层创建一个新层，选择白色笔刷，硬度为0%，大小为125px。选择“3D”图层的边框，然后在角落刷一下，设置透明度为85%。
 

_ueditor_page_break_tag_

Create another layer and get a Black Brush with a Hardness of 0% and a Master Diameter of 20pxand Brush it downwards while holding Shift. Use Gaussian Blur with 8px. Now ctrl+click on the “3D” layer icon then ctrl+alt+click on the “Top” layer mask icon. Finally invert your selection withctrl+shift+I and Delete the selection. Repeat the same process with a white Brush with 25px Master Diameter and set the Opacity to 70%.
新建层，然后选择黑色笔刷，硬度0%，大小20px。然后按住Shift键从下向下刷。然后使用高斯模糊，半径为8px。现在按着Ctrl点击“3D”图层的图标，然后按照Ctrl+Alt键点击“Top”图层的遮罩图标。最后用Ctrl+Shift+I反转选择，然后删除已选内容。用白色笔刷，大小25px，重复相同的步骤，设置透明度为70%。
 

Foreground & Background ColourYou can easily switch your background and foreground colour by pressing D. You can swap colours between the two by pressing X.
前景色与背景色
你可以使用D键将前景色和背景色回复为默认。你可以用X键来切换两个颜色。

Step 8: Adding Glow第八步：添加暗光
Create a new layer and name it “Glow”. Get the selection of the “3D” layer and move it up by 7px. Fillthe selection with the following colour: #6ab2f6. Before deselecting, shift the selection up by another3px and press Delete. Bring down the Fill to 70%.
创建一个新层，命名为“Glow”。选择“3D”图层的可选范围，并向上移动7px。使用#6ab2f6来填充选择的区域。在取消选择前，在向上移动3px然后删除。填充不透明度修改为70%。
 

Now give it the following Layer Styles.
现在修改层样式
 

_ueditor_page_break_tag_

Get the selection of the current layer and create a new layer. Get a White Brush with 0% Hardnessand 300px Diameter and and click once right in the center of the selection. Bring down the Opacity to 70%. Set the Blending Mode to Overlay.
选择当前层内容然后创建新层。使用白色笔刷，硬度为0%，大小300px，然后在选择的中间点击一次。将透明度修改为70%，设置融合模式为叠加。
 

Step 13: Adding Alphabets第十三步：添加字母
Create a new layer and select the Type Tool (T) with any colour. Use Arial as the font and set it toBold and 98px. Any font is fine actually. Now type in “Ps” and place it in the center of the icon. Right-click on the layer and click Rasterize Type. Transform it and shorten it slightly. Right-click the bounding box and click Perspective. Squeeze the top in to make it look 3D. Later add the followingLayer Styles with 0% Fill.
新建层，然后选择字体工具(T)。用Arial字体设置粗体，大小为98px，任意颜色。实际上字体无所谓。现在输入“PS”然后移动到图标的中心。右键图层然后点击栅格化文字。用变换工具稍微缩短一点。右键外围的边框选择XXXX。将顶部向内部挤让其看起来是3D。然后添加如图的样式，并修改填充透明度为0%。

Step 14: Final Details第十四步：最后的细节
Create a new layer. Get the selection of the “Ps” layer and nudge it up and right once each. Fill it with White then shift the selection back and press Delete. Set the Opacity to 30%.
新建层，选择“PS”层的内容，分别向上，向右轻移一次。填充白色，并轻移会原来位置删除，设置透明度为30%。
Finally create the last layer and get the selection of the “3D” layer. Fill it with White and applyFilter>Noise>Add Noise with Gaussian and Monochromatic enabled. Set the Blending Mode to Multiply and Opacity to 30%.
新建最后一个层，选择“3D”层内容。填充白色，并应用滤镜–>杂色–>添加杂色，设置为高斯分布，和单色。设置图层融合模式为“正片叠底”，透明度为30%。
Now you are DONE! You can hide or delete the background if you want to export it as an icon. But it’s not over if you want to make a set. For now your icon should look something like this.
现在终于完成！如果你想导出图标你可以隐藏或删除背景。如果你想做一个图标集那还没有结束。现在你的图标应该看来是这个样子的。
 

Step 15: Creating a Set第十五步：创建图标集
You can save this document and duplicate it. Open the new one and find for the layer called “Glow”. Temporarily hide the layer right above it. Now go Image>Adjustments>Hue/Saturation or (ctrl+U)for layer “Glow” and adjust the Hue to whatever you like. Once you’re done, go to the Layer Style>Outer Glow and adjust the colour to whatever you like. Now you can un-hide your above layer.
你可以先保存这个工程并复制他。打开一个新，然后找到图层Glow。暂时隐藏这个图层上面的图层。现在对“Glow”层选择图像–>调整–>色相和饱和度(Ctlr+U)并调整你喜欢的任意色相。完成后，选择图层–>图层样式–>外发光，调整任意你喜欢的颜色。现在你可以将上面的图层显示出来。
Navigate to your font layer. Delete it and repeat the process I taught you to create another alphabet you want. Remember to change the above layer which is the edge shine. Repeat this step for as many other icons you want.
找到你的字体图层。删除并重复之前创建字母的步骤。记得调整上面的边缘反光图层。
