Closing the diaphragm (going towards higher numerical values), the depth of field increases and it is possible to have sharp subjects exposed to different distances. The action reduces almost all the optical aberrations of the lenses, so that the image quality tends to increase, at least until diaphragms are reached so closed as to produce diffraction phenomena. The main consequence of the shutter speed on the image is the possibility to control the way in which the movement of the subject for Commercial Photography Los Angeles is shown.
With shorter times, commonly called fast (going towards higher numerical values, such as 500, 2000, etc.) even subjects in rapid movement will be frozen and will appear sharp as if they were still. With longer times, commonly called slow (going towards lower numerical values, such as 30, 15,8, etc.) the moving subjects will appear to be not very close together, shooting with slow times while moving the camera to follow the subject in the viewfinder.
