Grab your Nikon (or iPhone, or whatever) and snap a pic! The Philadelphia Photo Arts Center wants you to join the citywide effort celebrating Philly and photography in this annual submission-based exhibition. Each participant contributes one photo that is printed and displayed for free among a kaleidoscope of others. Your photo will sell for $25/print at the show on December 6, and 240 photos will be displayed on billboards or SEPTA buses and trains. How’s that for street cred?

All you have to do is:

1. Take a photo on October 26, anywhere in Philadelphia. Show off your photo on Twitter with #phillyphotoday.

2. Go to philaphotoarts.org, register with your basic information and upload yourphoto (only one!).

3. Watch your photo become part of a collective masterpiece!
