The dilemma is what can you or should you show in one frame when an event went on for more than that 1/250 of a second. My thinking has always been that you look for an image that is both accurate (meaning, it happened) and true (meaning, it represents the overall story). Does that open you up to criticism? Sure, but part of journalism is looking at the larger story and putting the individual elements within context.
The word-side has it much harder – how would you describe the nominee’s testimony? The other witness?
