All-black suit portrait AI prompt
Black suit, black shirt, black background — and gold as the only colour in the frame. The hard part is not the darkness, it is stopping the whole thing collapsing into one shape. Copy the free ChatGPT & Gemini prompt below and keep your own face.
Black on black is a lighting problem, not a colour one. A black jacket on a black background has almost no tonal difference to work with. Everything here — the side light, the open collar, the gold — exists to put an edge back in.
None of ChatGPT, Gemini or Nano Banana gives you a transformation-strength, identity-strength or beautify control, so the lock is a sentence rather than a setting: keep my exact face, relight and re-dress me, do not restyle my features. Tools that do put a denoise or strength slider in front of you are fine run low, around 0.20–0.35. The only beautify switch that matters here is the one on the camera or gallery app your reference photo came out of.
About this prompt
The crimson overcoat portrait is lit low-key too, but it gives the frame something to work against: a deep saturated crimson backdrop behind a black wool coat, so there is a tonal break between subject and background before the light does anything. This one has nothing: a black jacket, a black shirt and a black background, which on paper is three versions of the same tone stacked on top of each other.
That is the entire problem to solve, and it is a lighting problem rather than a styling one. Without an edge, the outfit and the backdrop merge and you get a floating head. So the prompt spends most of its words on separation — light from one side and slightly above, catching the shoulder, the lapel edge and the jaw, so there is a readable outline where the suit meets the dark.
Three details carry more weight here than they look. The open collar puts a wedge of skin at the centre of the frame, which is the brightest thing in the picture and where the eye lands first. The gold — chain, sunglass frame, watch — is the only colour anywhere, and metal is the one material that reliably throws a specular highlight in low light. And the crossed arms create horizontal lines across the torso, so the lower half is not one flat black rectangle.
How to use it
- Tap Copy prompt above.
- Open ChatGPT (image generation), Google Gemini or Nano Banana in image-to-image / reference mode.
- Paste the prompt and attach one sharp, evenly lit, front-facing photo of your face — flat light works best here, because the prompt supplies all the drama itself.
- Put the identity lock in the prompt — ChatGPT, Gemini and Nano Banana have no strength or beautify dials to set, so type it: keep my exact face, relight and re-dress me, do not restyle my features. If your tool does expose a denoise or strength slider, 0.20–0.35 is a sane starting point.
- Generate at 2:3 vertical, 1080 px wide or larger.
The three ways this goes wrong
The suit merges into the background. The commonest failure, and the fix is counter-intuitive: do not brighten the image. Raising exposure lifts the background to grey and you lose the black. Ask instead for a stronger rim light on the shadow-side shoulder — separation comes from a hard edge in one place, not more light everywhere.
The face turns plastic. Smoothing has happened somewhere, and it is almost never in the image tool — there is no beautify switch to turn off in ChatGPT, Gemini or Nano Banana. It is usually the phone camera or gallery app that produced your reference photo, which polished the skin before the model ever saw it. Upload an unretouched original, and say the texture line twice: AI image tools have a well-known habit of retouching on top of whatever you request.
The sunglasses come out crooked or mismatched. Eyewear is one of the things image models handle worst, because the two lenses have to agree across a face that is being re-rendered. If a frame comes back asymmetric, regenerate rather than trying to describe the fix — and if it keeps happening, drop the sunglasses line entirely. The outfit works without them.
Making it yours
- Silver instead of gold works, but reads cooler and quieter. Gold is warmer against skin and shows up better in this little light.
- Swap arms crossed for one hand adjusting a cuff if you want a less closed posture — it also puts the watch where the light can find it.
- Want it less severe? Change the black shirt to a charcoal or deep grey one. You lose some of the tonal purity and gain an easier picture.
- The 2:3 vertical is deliberate — it leaves black space above the head that makes the crop feel like a campaign page rather than a snapshot. Do not crop it out afterwards.
- If your reference photo has stubble or a beard, say so in the prompt. Models tend to shave you clean in formalwear unless told otherwise.
If you want low-key with colour in it, the crimson overcoat portrait uses the same narrow side light and puts a deep crimson backdrop behind you.
