name: restore-old-image description: This prompt instructs the AI to take an attached aged black-and-white photograph and restore it into a natural-looking, era-faithful color image by repairing physical damage artifacts, correcting tonal range and white balance, and applying realistic period-appropriate colorization while preserving authentic texture, identity details, and subtle film grain. The expected outcome is a clean, gently graded, film-like color version with controlled contrast, believable skin and material tones, minimal noise and sharpening artifacts, and no invented content or unnecessary cropping. compatibility: Requires betterprompt >= 0.1.0

What it does

This prompt instructs the AI to take an attached aged black-and-white photograph and restore it into a natural-looking, era-faithful color image by repairing physical damage artifacts, correcting tonal range and white balance, and applying realistic period-appropriate colorization while preserving authentic texture, identity details, and subtle film grain.

Inputs

imageInputs

This prompt requires exactly 1 image. You must pass exactly 1 image flag (no more, no fewer), in the order matching the descriptions below.

Index	Required	Description	Allowed CLI flags
1	Yes	image to restore	--image-input-url <url> or --image-input-base64 <base64> or --image-input-path <absolute path to image>

Models and options

This skill's modality is: image.

To discover which model values you can use (and which options keys/values are valid for each model), run:

betterprompt resources --models-only --json

Then filter the returned JSON array to entries where modality is "image".

How to run

Step 1: Collect inputs

First, run betterprompt resources --models-only --json and filter to modality: "image" to discover valid models and available options:

betterprompt resources --models-only --json

Use only the models and option values that appear in the filtered results.

Then collect all inputs from the human:

• Required images:
  • Exactly 1 images: image 1 (image to restore). Images must be provided in this order.
• Optional: model and options.
  • Present the human with the default model gemini-2.5-flash-image-preview and its available options. Look up gemini-2.5-flash-image-preview in the betterprompt resources output (filtered to modality "image") and show its availableOptions as: key: val1, val2 (default), val3 | key2: .... Mark a value (default) if it matches these defaults: {}.
  • If the human does not specify, defaults are used: model gemini-2.5-flash-image-preview, options {}. Other models from the resources call are also available.

If the required images are missing, ask the human for what's missing. Do not assume or fabricate values. Tell the human: "Please provide images in this order: image 1 (image to restore)".

Step 2: Run via BetterPrompt CLI

Use the frontmatter's name as the positional argument (for this skill, use restore-old-image).

Command form:

betterprompt generate restore-old-image \
  [--image-input-url <url>] \
  [--image-input-base64 <base64>] \
  [--image-input-path <absolute path to image>] \
  [--model <model>] \
  [--options <options JSON>] \
  [--json]

Notes:

• Pass each image using one of --image-input-url, --image-input-base64, or --image-input-path, in the order matching the imageInputs descriptions (image 1 first, then image 2, etc.).
• If the human does not mention a model, omit --model and BetterPrompt will use the default model: gemini-2.5-flash-image-preview.
• If the human does not mention options, omit --options and BetterPrompt will use the default options: {}.
• If the run times out, the response will include a runId you can use to fetch the result later.

Example (using defaults shown above):

betterprompt generate restore-old-image \
  --image-input-url https://example.com/image1.png \
  --model gemini-2.5-flash-image-preview \
  --options '{}'
