# Phone Screen Miniature Human Effect > This prompt instructs an AI image generator to composite a hyper-realistic forced-perspective photograph in which a real, full-body person appears miniaturized and physically standing on top of an iPhone’s glass screen while the phone is naturally held in a hand and a believable camera app interface remains visible beneath them. It specifies strict realism requirements—matching perspective, lighting, contact shadows, slight screen reflections, and partial UI occlusion by the person’s feet—while prohibiting any interpretation where the person is inside the screen, part of the display content, framed by the UI, floating, or rendered as a toy/CGI effect. The intended outcome is a single vertical street-photography-style image that instantly reads as a practical, physical illusion with consistent scale and photographic imperfections. - Skill: `betterpromptme/phone-screen-miniature-human-effect` (Agent Skill) - Install (CLI): `npx skillmds@latest add betterpromptme/phone-screen-miniature-human-effect` - Raw SKILL.md: https://api.skillmd.com/api/skills/betterpromptme/phone-screen-miniature-human-effect/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: AI & ML - Author: BetterPromptme (https://skillmd.com/u/betterpromptme) - Updated: 2026-09-10 - Page: https://skillmd.com/skills/betterpromptme/phone-screen-miniature-human-effect --- ## What it does This prompt instructs an AI image generator to composite a hyper-realistic forced-perspective photograph in which a real, full-body person appears miniaturized and physically standing on top of an iPhone’s glass screen while the phone is naturally held in a hand and a believable camera app interface remains visible beneath them.

You **must pass exactly 2 image flags** (no more, no fewer), in the order matching the descriptions below. | Index | Required | Description | Allowed CLI flags | | ---: | ---: | --- | --- | | 1 | Yes | Upload your phone photo | `--image-input-url ` or `--image-input-path ` | | 2 | Yes | Upload your portrait photo (outfit and pose will be kept exactly in the output) | `--image-input-url ` or `--image-input-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 2** images: image 1 (Upload your phone photo) and image 2 (Upload your portrait photo (outfit and pose will be kept exactly in the output)). 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 phone photo) and image 2 (Upload your portrait photo (outfit and pose will be kept exactly in the output))"**. ### Step 2: Run via BetterPrompt CLI Use the frontmatter's `name` as the positional argument (for this skill, use `phone-screen-miniature-human-effect`). Command form: ```bash betterprompt generate phone-screen-miniature-human-effect \ [--image-input-url ] \ [--image-input-path ] \ [--model ] \ [--options ] \ [--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 phone-screen-miniature-human-effect \ --image-input-url https://example.com/image1.png \ --image-input-path /path/to/image2.png \ --model gemini-3-pro-image-preview \ --options '{"aspectRatio":"3:4","resolution":"1K"}' ```
