Advanced AI Prompt for 85mm Minolta STF Fujifilm Natura 1600

Act as a Cinematic Low-Light Photographer. Design a prompt simulating the legendary Minolta 135mm STF (Smooth Trans Focus) lens, scaled to an 85mm field of view. The film simulation must emulate the rare, high-speed Fujifilm Natura 1600 film stock, designed specifically for flash-free dim environments. Interior: [LOW_LIGHT_INTERIOR]. Source: [CANDLELIGHT_SOURCES]. Mood: [SOFT_EXPRESSIONS]. The optical requirement is absolute perfection in the bokeh—zero hard edges or 'onion rings' in the out-of-focus highlights, just perfectly smooth, fading circles of light. The film emulation must introduce a heavy, cinematic ISO 1600 grain structure and the characteristic subtle greenish/cool color shift in the deep shadows.
