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. 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.

Inputs

imageInputs

This prompt requires exactly 2 images. 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 <url> or --image-input-path <path>
2	Yes	Upload your portrait photo (outfit and pose will be kept exactly in the output)	--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:

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 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:

betterprompt generate phone-screen-miniature-human-effect \
  [--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):

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"}'
