PF Photo Contest Champions It has been exactly TWO YEARS since our weekly photo contest has started, and it comes the time to pit our best photos against each other in a single thread to celebrate and conclude. There is one week to select your best photo from any of the years' contests to see who are the PF Photo Contest Champions. For this special occasion, I think we can stretch the one-time submit rule. I am eager to see what will be judged the Physics Forums Photo Contest's best photo . All of the previous contests can be found in the PF Photo Contest Winners thread.
