Having played with various settings taking runners I have decided upon this ploy for my next batch but just wondered if it was a frequently done method? Having used shutter priority at 1/250-1/320 this still gave some blurring on some shots, sometimes in areas I wanted to be blurred (hands/feet) but sometimes also in faces which I did not want. The next race I go to (I will be feet away from the runners) I am going to go for a higher shutter speed that should freeze the shot but then in PS I am going to use the lasso tool on feet & hands where applicable and use the motion blur tool to give the feel of movement/action. I don't want to use a super fast shutter speed/wide aperture/high ISO as I want some depth of field in the shot so am thinking 1/500. The pre-set sports mode seems to think I want to freeze flying golf balls. There is a pro guy that often takes shots at races and his pics are very crisp and un-blurred but very central with a very soft background and quite boring/un-action like which I want to avoid. Any tips would be much appreciated.
