There are many great things about photography, if you ask me.

But among its best qualities is the ability to transport us to a moment in time.

That is, a photograph is sometimes the most powerful reminder of events of the past, something that can often trigger a feeling or an emotion on a much greater level than other means of documenting the world's events.

This collection of photos certainly fits into that thinking.

This isn't a complete list of the world's most iconic photos, just a sampling of what people have been able to do with a camera when the moment counted.
