Black-and-White Window-Light Editorial Portrait from Your Own Photo
Turn your own photo into a black-and-white editorial portrait: soft daylight from a large side window, natural tousled hair, a dark knit cardigan and fine film grain.
Drag the handle: the original photo on the left, this prompt’s output in Gemini (Nano Banana) on the right.
The prompt
Upload your own photo to the tool first, then send this prompt.
Edit the uploaded photo. This is a photo edit, not a new portrait: do not regenerate, redraw, beautify or reinterpret the face. Keep the face exactly as it is in the photo — identical facial proportions, eye shape and spacing, eyebrows, nose, lips, jawline, beard and moustache shape and density, hairline and hairstyle, skin tone and every mark on the skin — and keep the same head angle and the same facial expression. If any instruction below conflicts with keeping the face identical, keep the face. Change only the following: turn the photo into a black-and-white editorial portrait framed from the chest up; soft daylight comes from a large window at one side, and the bright, blurred window frame is visible behind the person; let the hair look natural and slightly tousled, as if moved by a light breeze, without changing its length; replace the clothing with [a dark open-knit cardigan]; gentle contrast, deep blacks, fine film grain, real skin texture, 50mm lens with shallow depth of field. No text. Aspect ratio 4:5.
This prompt turns your photo into a black-and-white editorial portrait from the chest up: soft daylight comes from a large window at one side, the bright blurred window frame shows behind you, and the hair looks natural and slightly tousled, as if a light breeze had moved it. The example is a before/after, but the before photo is itself an AI-generated sample, not a real person: a selfie-style portrait of a woman with dark wavy shoulder-length hair in a grey t-shirt. The first paragraph is the “face lock”, which holds the face, head angle and expression; do not delete or shorten it.
Upload a sharp photo of your face and shoulders in soft light; hard shadows in the original clash with the window light.
Compare moles, brow shape and lips with your original; if the hair length or the face changed, regenerate.
The prompt works the same with a woman's or a man's photo, and a beard or moustache stays as it is; change the clothing bracket if a cardigan is not your style.
Use only your own photo or one of someone who agreed. Works with Gemini (Nano Banana) and ChatGPT; results vary from run to run.
How to use it in three steps
Open Gemini or ChatGPT and upload your photo.
Copy the prompt and replace the bracketed parts with your own subject.
Check the result and, in the next message, describe only what should change — step-by-step edits work better than one long instruction.
