More so than I think I recall anybody else. And when she had the degree she clutched it to her chest and teared up. It just made for a beautiful picture.” Photo by Elise Amendola/AP Photo Oprah Winfrey clasps Boston Mayor Thomas Menino’s hand. Both received honorary degrees in 2013. Photo by Elise Amendola/AP Photo Every Commencement at Harvard, the Yard fills with graduates and their families celebrating the completion of hard-earned degrees. But look closely in the front row, and you’ll see another jovial gathering. Press photographers from all over the region flock to the Yard to immortalize the regalia and traditions in Tercentenary Theatre. For the Boston press corps, noted for its collegiality, it’s a reunion of sorts — a chance to catch up while photographing some big names. After many years of recording the event, they all have their own favorite Commencement memories, and photos.Bloomberg News freelance photographer Neal Hamberg has attended Harvard Commencements since 1981. “Harvard knows how to throw a party. It’s almost a carnival atmosphere,” he said. “You’ve got balloons. Everybody’s happy, and of course everybody’s happy. They’re graduating from Harvard!” “All through the procession and when he was up on stage, he was just thrilled to be there and getting that degree,” Bloomberg photographer Neal Hamberg said of Bill Gates.

She speaks about photographing Oprah Winfrey in 2013 and Yo-Yo Ma ‘76 in 1991. “This wasn’t my first time at the rodeo,” said Boston Herald staff photographer Ted Fitzgerald, who has photographed Commencement since 1986 and has been in the business for almost 40 years. He noted the great visuals that come from the overall spirit of the day. As each School is announced, the graduates all raise symbols of their studies — the Law School yields gavels, the School of Education waves children’s books, and the Kennedy School throws inflatable globes. “You leave the Yard feeling good about what you have, as far as pictures go. You know that when you get back … they’ll be happy back there at the photo desk.”And there are always surprises. The honorary degree recipients are always top-notch and their identities are kept under wraps until Commencement morning. It’s not uncommon to see a head of state, a Nobel laureate, even a movie star on the stage.

Reuters staff photographer Brian Snyder, who first arrived at a Harvard Commencement in 1989, remembered the surprising moment in 2011 when Plácido Domingo sang the degree conferral to fellow honorand Ruth Bader Ginsburg. The U.S. Supreme Court associate justice gave the tenor a heartfelt embrace.The month of May is filled with commencements all over Cambridge and Boston, and experienced photographers are there every time, witnessing them all. Each ceremony has its traditions, but as Hamberg said: “Somehow it’s just not the same kind of atmosphere as you get in good old, historic Harvard Yard, with John Harvard looking down at you.” “This was truly an unplanned moment. He knew he was going to sing. She had no idea. And her reaction was really amazing. It was a real surprise for her,” Reuters photographer Brian Snyder said of Ruth Bader Ginsburg’s response to Plácido Domingo’s serenade.
