16f - 2.5 seconds
7.1f - 0.4 Seconds
2.2f - 1/30s
We can see how in order to compensate a higher aperture we have to decrease the shutter speed and vice-versa, in order to continue getting a good exposed photographed. Both f-stop and shutter speed go hand by hand. It is very important because in order to not get a strong DOF one should use a high aperture, but this closes the diaphragm of the camera, which represents less light coming in. In order to compensate that, one should decrease the shutter speed which will allow the shutter to remain open for a longer time, allowing more light to come in. However, if the camera is not on a stable place one will get a blurry/ghostly look on the image.
