Photo Tip: Frames can be literal or subtle. Using frames adds depth to the image and helps focus attention on the main subject.
拍摄小技巧：构图可以表达显性或者隐性的含义。构图不仅可以增加照片的景深也可以烘托主要人物。
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.
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。
