When my friend Lara Kahn recently married her fiance Craig Heller, she gushed to me about her wedding photographer Katie Osgood. She and Katie planned an engagement shoot on the day that New York state allowed same-sex couples to marry. They headed to their favorite marguerita joint, where Lara's engagement ring "appeared" in one of their signature slushy beverages. Then they took to the streets with their rainbow balloons, picked up a friendly pink flamingo along the way, schmoozed with cops on the street beat, locked lips in front of cheering crowds, and wound up in a secluded rooftop for more photos and a romantic evening. Engagement photo shoots are becoming more popular with couples. The best shoots collectively tell a story and document an adventure like the one Lara and Craig experienced on a day that was filled with historic wedding enthusiasm.
