The Magnum blog is a visual delight, just as you expect from the legendary photo agency. It’s a collective blog, where Magnum photographers and other contributors discuss and display their work. There’s also some bullish PR activity going on. Of course, one of the main attractions is that blog entries can be illustrated with classic photos from the Magnum archive. One thing the Magnum collective still has to learn, though: The blogging photographers don’t participate in the comments section, even when they deliberately want to start a debate about the amount of CO2 the cool jetting photographers are responsible for.
