【任务】对焦距离越近,景深就会变得越浅。如果被摄物体离相机很近,景深就会变得很浅。这个时候即使缩小光圈对于增加景深起到的作用也不是很大。在家里近距离拍摄水果时就会遇到景深太小的问题。拍摄时,前面的水果清楚了,后面的就不清楚;后面的水果清楚了,前面的就不清楚。甚至,同一只水果前后都不一样清晰。 [Task] the closer the focus distance, the depth of field will become lighter. If the subject is close to the camera, the depth of field will become very shallow. This time even if the aperture is reduced to increase the depth of field did not play a significant role. When the close-up shooting fruit at home will encounter the problem of too small depth of field. Shooting, the front of the fruit clear, the back is not clear; the back of the fruit clear, the front is not clear. Even before and after the same fruit are not as clear.
