我们发现，最佳相片通常都是景深很浅的，也就是说相片的主体焦点很清晰，但背景却有点模糊的那种，比如下面这张
We found that the best pictures have a very shallow depth of field, meaning that the subject is in crisp focus while the rest of the picture is blurry, like this
右侧是在f/2.8的光圈拍摄的：火炬灯为焦点，但是背后的房屋和树已经模糊得难以辨认了，这就是浅景深。
The right side, on the other hand, was shot at f/2.8: The torch is in focus, but the trees and the house are melted beyond recognition.
然后考虑景深深浅让背景聚焦清晰或模糊虚化。
Consider whether you want the background in focus or nice and blurry.
借此，距离主体较远的区域图像可模糊较严重，所以模拟出的浅景深效果较为自然。
Therefore, as the sectional images far away from the main body can be severely fuzzy, the simulation effect of the shallow field depth is natural.
这是因为图像可能有不同的模糊边缘宽度（景深）和在该中心通常有需要聚焦的被摄物体。
This is because an image can have a varying Blur Width (depth of field) and the subject which is to be in focus is usually in the center.
注意：为了让照片有更好的时尚效果，尽量不要使用景深效果，除了你的模特，模糊掉照片中的其他东西吧！
TIP:To get very fashion-esque shots, try using a short depth-of-field, blurring out all but the model herself.
