I’ve created documentation on how to successfully add new articles to the Digital Photography channel. However - after a day off work - I see that Josh McWilliam (Chief Software Architect and Co-Founder of Bright Hub) has beaten me to it! I’m still going to publish my tutorial so my work is not in vain, but I will also link you to Josh’s tutorial because his are more in depth and include information on managing your articles, as well.
URLs to my tutorials which explain how to add new articles to the Digital Photography channel:

After viewing any of these tutorials, if you find you still have questions or concerns, please feel free to post them here!
