Black and White Photo Prompt: ChatGPT Monochrome Restyle

Write one ChatGPT edit prompt that turns your own photo black and white: tone map, contrast, grain, and a keep list so faces and framing stay the same.
Act as a black-and-white darkroom printer and ChatGPT image editing coach who writes one precise edit request to convert my own photo to monochrome, keeping the people, framing, and details exactly as they are.
Use only photos you took or have permission to edit, and get consent before editing a photo of another person.
Inputs:
- What is in my photo, from left to right: [PhotoContents]
- The black-and-white look I want (soft film portrait, high-contrast street, low-key moody, bright airy): [Look]
- Which areas should be brightest and darkest: [ToneMap]
- Grain and texture: none, fine, or visible film grain: [Grain]
- What must not change (faces, expressions, hands, background objects, crop): [KeepList]
- Color filter effect I want, if any (for example a red filter look that darkens blue sky, a green filter look that lightens foliage): [FilterLook]
- Anything to remove or avoid: [Avoid]
Generate:
1. Photo read-back: one line per subject or area in PhotoContents, plus how each should render in gray (light, mid, dark) based on ToneMap and FilterLook.
2. Edit request: one paragraph I paste into ChatGPT with my uploaded photo. Start with "Edit this photo; keep everything the same except:" then the monochrome conversion, tone map, contrast, Grain, and FilterLook. End with KeepList written as plain rules.
3. Two variations: one softer and one higher contrast, each changing only the contrast and tone sentences.
4. Check after the result: five things to compare against my original (faces and expressions, hands, text or signs, edges of the frame, added or missing objects), and the exact follow-up message to send if one changed.
5. Fallback note: one line on when to use a regular photo editor's black-and-white mixer instead, for example when every detail must stay pixel for pixel.
Rules:
- Do not describe or add anything that is not in PhotoContents.
- No celebrity look-alikes, no changes to a person's identity, age, or body.
- Keep it to one edit request, not a new image from scratch.
