Retro Lo Fi Portrait Generator

What it does

This prompt instructs an image model to take a supplied reference photo and restyle it into a cinematic retro lo‑fi portrait by specifying a location, an unusual camera angle, and optional background props. It guides the look toward warm vintage color grading, soft film grain, muted tones, dreamy lighting, and off‑center composition to evoke a nostalgic, surreal film-photo feel. The outcome is a set of consistent, authentic-looking vintage portraits that can be rapidly varied by swapping simple placeholder values for place and added elements.

Inputs

textInputs

Pass each text input using --input <key>=<value> flags.

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.

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 text inputs:
  • place
  • weird_camera_angle
  • additional_elements
• Required images:
  • Exactly 1 images: image 1 (Your photo that you want to transform into a Retro Lo-Fi Portrait.). 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 any required text input or 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 (Your photo that you want to transform into a Retro Lo-Fi Portrait.)".

Step 2: Run via BetterPrompt CLI

Use the frontmatter's name as the positional argument (for this skill, use retro-lo-fi-portrait-generator).

Command form:

betterprompt generate retro-lo-fi-portrait-generator \
  [--input <key>=<value>] \
  [--image-input-url <url>] \
  [--image-input-path <path>] \
  [--model <model>] \
  [--options <options JSON>] \
  [--json]

Notes:

• Pass each text input as a separate --input <key>=<value> flag.
• Pass each image using --image-input-url 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 retro-lo-fi-portrait-generator \
  --input place=<value> \
  --input weird_camera_angle=<value> \
  --input additional_elements=<value> \
  --image-input-url https://example.com/image1.png \
  --model gemini-2.5-flash-image-preview \
  --options '{}'
