Actually i remember you (NK) speaking in an interview regarding a shoot where it seemed you were floating, with pretty much every frame being wholly satisfying. This sence of the picture taking process being so finely tuned you can almost do no wrong is,I belive,to do with the photographer/model dynamics more than anything else. There can be any number of other factors we associate with photography excelence(great exposure/focus,great styling,exciting lighting) present but if the photographer/model dynamic is not there although the photos may indeed look great and the viewer may think there was a great buzz on set,the truth is the kind of adrenelin a photographer feels(If theyre lucky) will not have been felt. To take this further i believe the dynamics can be finer tuned so that the model is more engaged in the shooting process,thus pushing the exchange further. It has worked for me and as a result I put an unusual amount of time and communication into the casting.
