Depth of Field

In the first picture, I used the the F stop 8/0 and the shutter speed of 1/4. If you notice the picture, the picture is focused on the foreground instead of the middle ground and background. In the meanwhile, the picture in the middle is different from the top picture. I used the F stop 5.6 and the shutter speed of 1/4. If you study the picture you will see the picture is focus in the middle ground. You will also notice that it' different from the foreground picture. On the other hand, the picture in the bottom is background. I used the F stop 3.4. If you noticed, the picture is focus in the background.
