Transform this photo to look like an authentic 1970s vintage photograph. Preserve all facial features, identity, and expressions exactly — do not alter faces, skin tone, or body proportions. Change clothing to 1970s earth-tone fashion: wide-collar shirts, flared trousers, knitted vest, mustard yellow, olive green, rust orange, beige, brown tones. Change hairstyles to natural feathered 1970s styles with side parts and soft layers. Replace background with a vintage Indian middle-class home setting with wooden furniture, old curtains, period walls, simple household objects. Apply warm amber, brown, cream film tones, subtle film grain, slight softness, mild color fading, gentle vignetting. Lighting should be soft natural daylight with warm highlights and moderate contrast. No modern objects, logos, or HDR effects. Make it look like a genuine 35mm analogue film photograph from 1970.
