Master Shooting modesThe best place to start is with shooting modes. The shooting modes will most likely be found on a dial labelled with ‘auto, Av, Tv, P, M’ and maybe more. Selecting a shooting mode will determine how your camera behaves when you press the shutter, for example, when ‘auto’ is selected, the camera will determine everything to do with the exposure, including the aperture and shutter speed. The other modes, ‘Av,Tv, P, M’, are there to give you control:Don’t worry if your mode dial looks a little different; different manufacturers use different abbreviations for the shooting modes. Your mode dial may have the letters ‘A, S, P, M’ (instead of Av, Tv, P, M), yet they all function in the same way. Below, I have given each abbreviation for the given mode.
