I've stumbled across the Social Documentary website, a new addition to documentary photography on the web, and which features documentary photography from around the world.
According to its self-description, Social Documentary welcomes "professional and amateur photographers, journalists, NGOs, students—anyone with a story to tell and a collection of good photographs" and who seek to create easy and affordable websites on SocialDocumentary.net.
Its secondary goal "is to create an online image bank of quality photographs documenting all aspects of the world created by an international collection of photographers. "
The Terms & Conditions are here, and, as usual with such ventures, make sure you read and accept these before deciding.
