Here is a moral question for you. This is an imaginary situation, but it may be interesting deciding what you would do. The situation: You are in the Midwest, and there is a huge flood in progress.

If you were to stumble across Bill Clinton struggling to keep from being swept away in a raging river and you had a choice of rescuing him or getting a Pulitzer prize-winning photograph of the death of a President, what shutter speed would you use?
