When learning photoshop some ideas to share.
皮肤处理（Skin treatment）
一般情况下正常肤色之比是红比绿50~60%，绿比蓝30~40%。例如蓝色较低，人的肤色便偏黄（蓝的互补色是黄）。
Under normal circumstances the ratio of normal skin color is red than green, 50 to 60%,green than the blue,30 to 40% . For example, if blue is low, people of color will be yellow (the complementary color is blue and yellow).
搭配（Colors）
当使用四到五种纯色进行搭配的时候，注意只要色相、纯度、明度三个属性中有一个属性是基本相同或者接近，搭配起来基本上都不会觉得太牵强。
When using four to five kinds of solid color to match, pay attention as long as hue, purity, brightness, there is a property of three properties are the same or close to, with thembasically not too far-fetched.
人物图片处理（People photo processing）
加背景光，背景虚化，突出主题。
