The photography of HCB is truely magnificent. The decisive moment can be predicted, and plannen if one has time. You find an interesting venue, you set up shop, get exposure details etc. and wait until what you think will happen happens, and surely it will most of the time, and because of your stanionary character you will be able to adjust to lightning conditions and range all of the time, this in order to get the right shot at the right time.
Think of HCB "man jumping over puddle shot" many people think it was composed, well it was composed in such a way that HCB was ready for it, and could shoot at the point required ....
Many good street shots are done that way, all you need is time and patience, and to try and find a stationary spot. It might take a number of days to get the shot you want, but that will be all part of the fun...
