Shoot your lunch. Not like Facebook founder Mark Zuckerberg, who now only eats what he kills. With a camera.

Take a photograph of your lunch, or anything, and upload it to Picture This, Baltimore.

For the second time, the Baltimore Sun is chronicling a day in the life of Baltimore. If you have a camera or a cell phone with a camera, we want to see what you see -- the places you go, the people you meet, whatever else you may encounter on one Tuesday in October.

Upload your photos from Facebook, Flickr, Picasa, Instagram and more.  To upload via Twitter, send a tweet to @baltimoresun with the hashtag #picturethis. Email your pictures to pictures@baltimoresun.com.

I want to see what you eat.
