[ 1 ] We'll call the original layer "ORIGINAL", now duplicate ORIGINAL and place it above that layer. (We'll call this "BLACKWHITE")

ctrl+j 複製一個圖層 取一個你喜歡的名子

[ 2 ] Change the Blending option of BLACKWHITE to "Overlay"

疊加模式改成overlay

[ 3 ] Go to Image > Adjustements > Desaturate (SHIFT + CTRL + U)

直接用快速鍵 shift+ctrl+u 按一下，降低飽合度

[ 4 ] Now invert BLACKWHITE: Image > Adjustements > Invert (CTRL + I)

ctrl+i 按一下反轉黑白

[ 5 ] And add a gaussian Blur to it (Filter > Blur > Gaussian Blur) around 40 pixels (This causes the so called 'bleeding' of the edges, tweak the amount to personal likings)

加入高斯模糊值約40

這時後效果是醬子

[ 6 ] Now duplicate ORIGINAL and place it above BLACKWHITE, name this layer "LINEAR_LAYER"

再從原圖複製一個圖層在最上面

[ 7 ] Change the blending type of LINEAR_LAYER to "Linear Light"

[ 8 ] Give LINEAR_LAYER an opacity around 62%. And you're done (For better results, tweak this percentage)

改它的透明度覺得好看就好，當然不是每張圖都很美所以就在另外自己調調色吧
