Your Smile Before You See the Dentist

{ "subject": "If a photo is uploaded, it is the SAME person in that photo and nobody else: preserve the shape of the face, the drawing of the lips, the colour and shape of the eyes, the eyebrows, the skin tone with its pores, freckles and expression lines, the cut and colour of the hair, the apparent age and the gender. Preserve as well the shape and the width of each of that person's teeth, the spacing between them and the height of the upper lip over the gum: change only what the teeth field tells you to change. Do not make the face younger, do not slim it, do not narrow the nose, do not enlarge the mouth, do not erase marks on the skin and do not swap the smile for a generic one. With no photo uploaded, create a fictional Brazilian woman of about thirty five, face 100% original, light brown skin with visible pores, faint freckles across the nose and fine lines at the corners of the eyes, dark brown eyes looking straight into the camera, dark brown straight hair at shoulder length tucked behind one ear", "teeth": "An open, relaxed smile showing the whole of the upper teeth and only the thin edge of the lower ones. The colour comes out TWO SHADES lighter than the teeth in the uploaded photo, and no more than that: warm ivory white, never paper white and never the same white as the white of the eye. Each tooth keeps its real gradation - the edge slightly translucent and greyish, the neck near the gum a shade warmer and more opaque. The edges of the four upper incisors draw a single curve that follows the line of the lower lip, with the central pair a hair longer than the laterals and the corners rounded; the teeth keep different widths from one another, the way real teeth do. The upper lip covers the gum line, leaving at most a thread of gum showing above the front teeth", "wardrobe": "A plain knit top in olive green, round neck, no print, no brand print and nothing around the neck", "action": "Facing the camera, shoulders slightly relaxed, head straight, smiling for real, with the skin around the eyes moving with the smile", "scene": "A plain wall in a light greyish beige, completely out of focus, with no object, no frame and no texture", "composition": "A vertical portrait in 3:4 proportion, framed from the top of the head to the top of the shoulders, face centred, the mouth a little above the middle of the frame so that the smile is the subject of the framing", "camera": "Camera at eye level, straight on, short portrait distance, the look of an 85mm lens at a wide aperture, shallow depth of field that softens the wall and keeps the teeth and the eyes sharp", "lighting": "Soft studio light from above and slightly in front, with a reflector below the chin opening up the shadow of the lip; two small catchlights in the eyes and a soft, spread sheen on the teeth, never a mirrored highlight or a star of light", "color_palette": "Warm neutrals: beige, taupe, olive green in the top and ivory in the teeth, low and even saturation", "style": "Natural editorial portrait photography, realistic, skin texture preserved, no beauty retouching, no skin smoothing and no filter aesthetic", "materials": "Enamel with a damp, translucent shine at the edges, lips with fine line texture, cotton knit with a visible weave", "details": "What proves the result is achievable is the MEASURE: two shades of whitening and no more, the curve of the edges following the lower lip, and the thread of gum at most a millimetre high. Preserve the translucency at the edge of each tooth, the different widths between the teeth, the dark buccal corridor at the corners of the mouth, the expression lines the smile creates and the real texture of the skin", "negative_prompt": "toothpaste advert smile, flat white with no translucency, teeth the same white as the white of the eye, teeth all the same size and the same length, teeth too large, tooth edges in a straight line, a wide band of gum showing, a generic smile swapped in for the person's own, a face made younger or slimmer, plastic or smoothed skin, beauty retouching, mirrored highlight or star of light on the teeth, text, letters, numbers, watermark, frame, logos, real brands, deformed hands, likeness to a real famous person, AI artefacts" }
