"Just checked out the Reuters Photos of the Year. (Thanks, btw.)
Aside from their value as records of events, that selection of works could be used as a lesson in photography as well. Not just technique, and lighting and technical aspects. But more importantly, what "makes" a photo (a couple of them I found to be examples of what doesn't) and how a story, a message, a narrative or an emotion can and should be conveyed."
