I just got this in an email and thought it was funny!
I have a moral question for you. This is an imaginary situation, of course, but one of those things that gets you thinking.
You are in the Middle East and there is a huge flood in progress. Many homes have been lost, water supplies compromised, and structures destroyed. You are a photographer getting still photos for the CNN news service and are traveling alone, looking for poignant scenes.
You come across Osama bin Laden who has been swept away by the floodwaters. He is barely hanging onto a tree limb and is about to go under. You can either put down your camera and save him or take a Pulitzer Prize winning photgraph of him as he loses his grip on the tree limb.
So here's the question and think carefully before you answer the question:
Which lens should you use?
