پرامپت تبدیل عکس به عکس قدیمی سیاه‌وسفید دهه ۶۰ و ۷۰ | Vintage Film

Convert this photo to look like it was taken with an old analog camera from the 1960s-1970s. It MUST be black and white — no color at all, full grayscale. Apply heavy visible film grain, scratches and dust marks on the film negative, slightly faded contrast with deep blacks and bright whites, strong vignette darkening at corners, and a nostalgic old-world feel. The result should look like a genuine vintage black and white photograph found in a family album from decades ago.
