"Transform this photo into an overcast 1990s flannel porch portrait. Keep my exact facial identity, features, age, and skin tone completely unchanged, and do not alter my face or add a second face. Dress me in a plain graphic-free tee or chunky knit. Light the scene with an on-camera flash combined with leftover warm tungsten light in the room. Add drugstore print grain and a faint warm or cyan cast. Output as a 4:5 vertical portrait."
💡 Expert Insight: This prompt is effective because it gives the model specific 1990s photography cues—flash, tungsten light, drugstore grain, and a 4:5 composition. For stronger results, keep the color cast and grain subtle so the image feels naturally aged rather than artificially filtered. 📸
