Usually we are more focused on things in front of our lens. In this week’s #Flickr Friday we invite you to a challenging theme: What are the things #BehindTheLens when we take a photo?

No, not the sensor or film. Not that simple. :)

Take a great photo on this theme before the next Friday, share it to the Flickr Friday group, and we will feature our favorites right here in the Flickr Blog.
