Natural shadow

Start with the right photo.

Use an object with a visible base and specify the surface and light direction.

What to expect

Add a grounded contact shadow matching the light direction without altering the product.

Keep an eye on

Recognizable identity, silhouette and important visible details. Compare the output to the original before using it.

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 grounding a product in a studio scene. The shadow must meet the contact point; a displaced shadow can make the object appear to float.
