Black-and-white photo prompts

Black-and-white photos go two ways with AI. You can bring an old family picture into colour, with natural skin tones and the clothing colours you remember, or you can take a modern colour photo and give it the timeless look of a studio portrait, a film noir still or a high-contrast print.

Both work in Gemini and ChatGPT with a photo you upload. For colourizing, tell the AI the colours you know; for converting, say how much contrast and grain you want. Keep your original file either way.

How to use it

Three steps, about a minute

  1. 1

    Scan the old photo, or photograph it flat in soft daylight with no glare on the surface.

  2. 2

    Upload it to Gemini or ChatGPT, paste the prompt and list any colours you remember.

  3. 3

    Compare the faces with the original. Keep both files: the colour version is a new picture, not the record.

Make it yours

  • Colours you know: "her saree was maroon with a gold border, his shirt was white, the door was blue".
  • Era: say the decade ("1950s", "1970s") so the AI picks period-accurate colours.
  • Converting to black and white: ask for "deep blacks, bright highlights, fine grain" for a print look.
  • Mood: film noir adds hard light and shadows; the studio portrait prompt keeps it soft and classic.

If it goes wrong

Colours look too bright
Add "muted, film-era colour, not oversaturated".
Skin tones look wrong
Ask for "natural, warm and varied skin tones" and name them if you can.
Faces changed
Reply "keep every face exactly as in the original, change colour only".
Black and white looks flat and grey
Ask for "high contrast, deep blacks, bright whites".

FAQ

Questions, answered

How do I colourize a black-and-white photo for free?

Upload the photo to Gemini or ChatGPT, both of which have free tiers, and paste the colourize prompt. Add any colours you remember for a more accurate result.

Are AI colours accurate?

No AI can know the real colours. It makes a believable guess from the period and the shades of grey, so tell it what you know and treat the result as an artistic restoration, not a record.

How do I make a colour photo black and white with AI?

Use the high-contrast or studio portrait prompt. Unlike a simple filter, the AI can also change the lighting and background to suit black and white.
