IMO, it's ok to take lots of pictures and then to pick the best later because sometimes it is only the distance in time that allows you to see exactly what you want.
IMO, it is not OK to skip the part of looking hard at what you have made, deciding which one is the best and then refining it.
Imagine taking a single glass of a truly great wine, it will be memorable.
If that glass of wine is only one of a dozen lesser wines, then the impact and the memory will inevitably be dispersed.
