Hi sir. How many ISO and shutterspeed should be used to take a moving object sir? Can you tell me. Because I often fail to aim at moving objects.

hey. there is a lot of factors for that, mostly how fast the object is moving, and for ISO how much light is there. it is a testing thing until you learn to feel it. Try to keep the ISO as low as possible for the shutter speed you need.
