Christmas Flash Film Portrait

---
name: christmas-flash-film-portrait
description: This prompt instructs an AI image editor to take a single uploaded portrait photo and transform it into a realistic, vintage-style Christmas dinner film photograph shot indoors at night with direct on-camera flash. It specifies a warm, nostalgic 35mm aesthetic with visible grain, subtle imperfections, and cozy holiday decor while keeping the subject’s identity, facial features, age, skin tone, and gender presentation unchanged. The expected outcome is an editorial yet candid-looking festive portrait—tasteful and commercially appropriate—without adding text, logos, fantasy elements, or non-photographic styles.

## What it does

This prompt instructs an AI image editor to take a single uploaded portrait photo and transform it into a realistic, vintage-style Christmas dinner film photograph shot indoors at night with direct on-camera flash. It specifies a warm, nostalgic 35mm aesthetic with visible grain, subtle imperfections, and cozy holiday decor while keeping the subject’s identity, facial features, age, skin tone, and gender presentation unchanged. The expected outcome is an editorial yet candid-looking festive portrait—tasteful and commercially appropriate—without adding text, logos, fantasy elements, or non-photographic styles.

## 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 | Upload your photo. A portrait image is recommended for best results. | `--image-input-url <url>` or `--image-input-path <path>` |


### 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:

```bash
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:

```bash
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 (Upload your photo. A portrait image is recommended for best results.). Images must be provided in this order.
- Optional: model and options.
  - Present the human with the default model **`gemini-3-pro-image-preview`** and its available options. Look up `gemini-3-pro-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: `{"aspectRatio":"3:4","resolution":"1K"}`.
  - If the human does not specify, defaults are used: model `gemini-3-pro-image-preview`, options `{"aspectRatio":"3:4","resolution":"1K"}`. 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 (Upload your photo. A portrait image is recommended for best results.)"**.

### Step 2: Run via BetterPrompt CLI

Use the frontmatter's `name` as the positional argument (for this skill, use `christmas-flash-film-portrait`).

Command form:

```bash
betterprompt generate christmas-flash-film-portrait \
  [--image-input-url <url>] \
  [--image-input-path <path>] \
  [--model <model>] \
  [--options <options JSON>] \
  [--json]
```

Notes:

- 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-3-pro-image-preview`**.
- If the human does **not** mention options, **omit** `--options` and BetterPrompt will use the default options: **`{"aspectRatio":"3:4","resolution":"1K"}`**.
- If the run times out, the response will include a `runId` you can use to fetch the result later.

Example (using defaults shown above):

```bash
betterprompt generate christmas-flash-film-portrait \
  --image-input-url https://example.com/image1.png \
  --model gemini-3-pro-image-preview \
  --options '{"aspectRatio":"3:4","resolution":"1K"}'
```
