AI Prompt for Japanese High School Graduation Photo with Retro Instant Film Effect

"A realistic instant film Polaroid photo lying flat on a light wooden tabletop, photographed from directly above. The instant print has a thick white border with a wider bottom margin and slight natural wear, with the photo area showing an indoor Japanese high school classroom group portrait. Inside the photo, about 35 graduating students in dark school uniforms are gathered in 4 loose rows in front of a green chalkboard, posing casually and tightly packed together. Most are teenage boys in black gakuran-style jackets or dark blazers with white shirts and ties, and several teenage girls wear dark blazers with blue plaid skirts. One girl near the front left stands out in a white cardigan and blue plaid skirt. Many students hold up peace signs, some crouch in front, and a few sit or recline on the wooden floor in the front row. Faces are intentionally obscured with soft square mosaic blurs, but the overall feeling is candid, nostalgic, and celebratory. On the chalkboard, hand-drawn Japanese graduation messages in chalk include large central text reading "3年B組" and celebratory doodles and writing around it such as graduation-themed congratulations. The classroom has white walls, a round wall clock above the chalkboard, a fluorescent ceiling light fixture, and subdued indoor lighting. The image should feel like a slightly dim early-2000s or 2010s snapshot with mild grain, soft focus, authentic flash photography, and natural color fading, emphasizing a sentimental end-of-school memory preserved as a physical instant print."
