by 今日小编给大家带来的是<谈ps系列（3）|ps中羽化功能的介绍及应用
PART.1.
羽化是ps专业术语，羽化工作原理是令ps选区里外对接一部分模糊化，具有渐变色的功效以达到自然衔接效果，是ps以及其他版本号里的处理照片的重要方式。
羽化快捷键供平时我们应用：
CTRL ALT D
PS CS3、CS5版本羽化键盘快捷键为：Shift F6
Feathering is a ps term. The principle of feathering is to blur the inner and outer parts of the selection, and play the role of gradient to achieve the effect of natural connection. It is an important tool for processing pictures in ps and other versions.
The shortcut keys for feathering are usually used by everyone:
CTRL ALT D
Feathering shortcut keys for PS CS3 and CS5 versions are: Shift F6

下面举一个具体的应用事例来为大家展现羽化效果
Next, a practical example is given to show you the effect of feathering.
1、最先先用椭圆形选择设备将图上的碗挑选；
1. First use the ellipse selection tool to select the bowl in the picture;
2、应用涂料桶专用工具把它添充为随意色调；
2. Use the paint bucket tool to fill it with any color;
3、新建图层，将涂层设为“累加”，就能发现照片边缘融合不和睦，很生涩。
3. Create a new layer and set the layer to “Overlay”, and you will find that the edges of the picture are not harmonious and blunt.
4、这时候，大家新增加一个涂层，将羽化值设为20，一样应用椭圆形选区将碗的样子挑选出去；
4. At this time, we add a new layer, set the feathering value to 20, and also use the elliptical marquee to select the shape of the bowl;
5、在羽化数值20的条件下将第二次选择的选区添充为红色；
5. Fill the second selected marquee with red under the condition that the feather value is 20;
调节羽化系数的尺寸能够调整边缘的朦胧水平，羽化值越低，模糊不清边缘实际效果就越少；羽化值越多，模糊不清边缘实际效果也就越大。如下图所示实际效果所显示：
Adjusting the feather value can adjust the blur degree of the edge. The smaller the feather value, the smaller the effect of the blurred edge; the larger the feather value, the greater the effect of the blurred edge. The effect is shown in the following figure:
羽化处理后的地区更真实，不容易觉得有很多的ps痕迹。
Feathered areas are more natural and won’t feel like there are too many ps traces.
