Portal reveal

Start with the right photo.

Use a clearly framed subject and indicate which part should emerge through the opening.

What to expect

Keep the subject recognizable while it emerges partly through one luminous architectural portal.

Keep an eye on

Compare subject count, recognizable identity, proportions and text against the original. Deliberate transformations are described in the prompt.

Make it yours, step by step.

1. Adjust the recipe to describe your subject and preferred background.
2. Copy the complete recipe, then open ChatGPT.
3. Upload your photo in ChatGPT and paste the recipe. The short code alone is not an official command.
4. Inspect identity, text and proportions. Ask for a targeted correction if needed.

Where this effect helps — and its limits.

Useful for a portal scene concept. Check the boundary where the subject crosses the opening so it stays one continuous object.
