Vintage Couple Collage

Generate a photorealistic 4x4 grid collage, 16 photos in total. The scene features a couple in their twenties taking pictures of each other and selfies with a vintage point-and-shoot camera, like clumsy yet intimate travel memory photos. Each grid is a different moment: hand shake, slight out of focus, tilted composition, flash, film grain, warm vintage filter, slight light leak, natural expressions. The overall look is like a real old album contact sheet.
