Wedding photography captions should be engaging and capture the emotion of the moment. Popular options include short and sweet phrases like "Forever starts now," "Two souls, one heart," or "Happily ever after." You can also add a personal touch by mentioning the couple's names, the wedding date, or a special detail about the photo. For a more romantic feel, consider quotes like "To love and be loved is to feel the sun from both sides" or "Every love story is beautiful, but ours is my favorite".
