A photographer is looking for a couple he captured in a picture-perfect proposal, shot as the sun set over Yosemite. "I couldn't believe what was happening," Matthew Dippel told Inside Edition. "... I just pointed and snapped away.” Dippel was visiting the California national park in California when he saw a magical moment taking place across the canyon. Now he wants to know whose image he captured, turning to social media to track the couple down in the hopes of giving them the stunning photo.
