Flickr has a stunning collection of images, many of them by superb photographers. While the site's tagging system does a good job of filtering content, the baffling number of images can still make it hard to narrow down the results. That's where groups come in. Of course, the sheer number of groups can be overwhelming as well. Often, groups remain hidden among the masses until someone invites you to join one of them.

Here are a few excellent Flickr groups:

• Lights and Shadows
• DEL*TE ME! Uncensored - Where Cyanide Meets Aesthetic Disco
• 1000 views + 100 favourites
• Utterly Surreal
• Colours Of The World
• Self-Portrait Experience
