at what point do you just take the photograph? its all a battle of compromises anyways ...
(im not going to ask when you know if your print is done cause nothing is ever done )
In the context of a professional hired gun, my goal was that the technical aspects of the craft were down pat, so that complex situations are not that difficult to resolve quickly. You might actually spend a few moments thinking through the puzzle in the lulls, so the technical things fall into place via the background knowledge applied to circumstance, and the shooting happens quickly and consists of a lot of people arranging. Trying to do all the wedding formal shots as quickly as possible, so as to not keep everyone waiting at the reception, means a good handle on both technical and organizational skills.
Or showing up at an event, assessing the best location to set up a shooting location and lighting, needs to be done quickly, so that it is only a matter of posing groups and moving them through in a smooth progression.
I had a lot of photojournalism experience relatively early on, and one needs to be quick yet technically proficient to get the shots in as short a time as possible...capturing candid action forces that skill. You get the shot, or it is gone in a moment.
