If you've never visited our sister site Londonist and checked out their fantastic Photoshop-based feature, Touch Up London, you really should right this minute. Every week, Londonist editors ask their photo editing-skilled readers to take an iconic image of their city and "touch it up" into something funny, freakish, or just plain wonderful. There have been 55 selected Touch Up London images already, but this one, by Londonist reader Andy Fisher, is one of our favorites. Do click through and check out the rest of them.

So since we're well into the Dull Days of August and we have a sneaking suspicion there are quite a few of you sitting at your desks, longing for distraction now that your boss has finally left for vacation, we thought we'd throw the floodgates open on a little Touch Up D.C. contest. We're not sure how long we'll let it go on just yet -- that will depend on what the response is like -- but if you'd like to "touch up" a landmark, street scene, or any other image that represents the District, upload it to Flickr and tag it with "touchupdc" -- we'll take a look at what you send in and post our favorites throughout the month of August. Please DO NOT upload your Touch Up entries to the regular DCist Photo Pool, however, as we don't want anyone to end up getting confused! And remember, be as creative as you can be. There are no real rules to this endeavor other than it has to be based on an image of something in D.C. (D.C. metro area is OK too). Other than that, the possibilities are endless.
