High Contrast BW Photo Grid

High-fidelity, faithful facial replicas. Maintain 100% facial similarity and identity of the original user images provided to the original characters. The user's original image is for identity reference only. You must replace the original poses, costumes, and backgrounds with the new styles described below. Apply the following style: use a 2x2 layout with a four-frame photo grid collage, similar to the sequence of black-and-white camera bursts for snapshots. The overall composition should be customized for a 3:4 portrait aspect ratio. The photography style is high-contrast black-and-white studio photography. Crucially, the final image must be clean, sharp, and high-resolution rendered, with little or no digital noise or film grain. All four panels feature seamless, solid-colored medium gray studio backgrounds. All panels are illuminated by intense, direct onboard front flashes. This creates bright, striking highlights on facial features and hair, while casting sharp, clear, opaque black shadows on the gray background directly behind the subject. Apply a slim figure and clear collarbones for the main body. Hair is dark, medium-length, wavy, severely tousled, and messy, with noticeable volume. Due to grayscale and flash, the skin tone appears high-profile and fair. Her makeup features structured dark eyebrows, eyelashes covered in heavy mascara, and dark matte lip color. In all panels, the subject wears a strapless outfit, leaving the shoulders, collarbones, and upper chest fully exposed to the camera. At the bottom of her neck wears a delicate, slender metal chain necklace. You must place the person in the user's photo into each of these four panels and change their pose and expression as follows: Top left panel: Close-up, the subject slightly turns to the side, past the left shoulder, looks back at the camera, wears an extremely wrinkled, mischievous smile, eyes tightly closed; Her hair hangs down to the left, revealing her right neck and shoulder, with the necklace not visible. Top right panel: Frontal close-up portrait; The subject looks directly directly at the camera, supporting their face with both hands, and using their index and middle fingers to pull horizontally outward from the outer corners of the eyes; Her hair is parted in the middle, and the necklace is visible. Lower left panel: Frontal close-up portrait; The subject stares directly at the camera, with an exaggerated, asymmetrical frowning and pouting expression, a protruding lower lip, and relaxed, drooping shoulders; Necklaces are visible. Bottom right panel: Frontal close-up portrait; The main body raises both arms, hands behind the head, index fingers pointing straight upward, simulating an angle; His expression is a funny wide-eyed ghost face, mouth tilted to one side; Because of the raised posture, the inner arm is visible, and the necklace is visible. The overall vibe is spontaneous, expressive, playful, and slightly rebellious.
