One of the best blogs for photography comes from the Magnum photo agency that posts regular images and articles by their photographers.
Magnum photographer Simon Wheatley gives some insight into the decline in street photography in France after changes to the privacy laws. A similar sort of legislation is being looked at in the UK that may introduce similar types of privacy measures very soon. Several of Simon's images about the alienation of young people are included in the piece.
The blog is updated often with new images and discussions about the vast Magnum back catalogue of images and is a great resource for anyone new to the world of photography.
