Advanced AI Prompt for 85mm Petzval Lens Kodak TRI-X 400 Grittiness

Act as a Steampunk-Era Portrait Photographer. Create a rugged portraiture prompt simulating the optics of a modern brass New Petzval 85mm Art Lens. The development must precisely emulate Kodak TRI-X 400 black and white film, featuring heavy, clumpy silver-halide grain and brutal, high-contrast monochrome tones. Subject: [RUGGED_SUBJECT]. Shadows: [SHADOW_DEPTH]. Texture: [TEXTURE_DETAIL]. The core mandate is to render the Petzval's unique optical signature: a violently sharp center focus point that rapidly deteriorates into a dizzying, spiraling, painterly bokeh effect towards the edges of the frame, amplifying the gritty texture of the subject.
