Architectural shadow composition

Start with the right photo.

A room photograph with readable window mullions and walls or flooring to receive their shadows.

What to expect

Use hard directional sunlight through the existing left window to cast one large graphic window-frame shadow across the back wall, sofa and floor.

Keep an eye on

A single view cannot establish measurements or hidden construction. Check furniture count and window alignment.

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.

Choose the change deliberately.

Strong cast shadows can become compositional shapes. Choose a source direction and preserve the object's contact points so the graphic treatment still belongs to the scene.

Review and refine the result

Inspect whether a shadow suggests an extra object that is not present. If shapes become confusing, reduce overlap and keep the subject brighter than the darkest cast areas.
