Prompting Strategies

Basic Edits

Simple, direct instructions work best:

Controlled Edits

Be explicit about what to preserve:

Change the setting to nighttime while maintaining the exact same
composition and the painting's artistic style

Complex Transformations

For dramatic changes, be specific about preservation:

Transform the modern office into a Victorian library with the same
furniture arrangement. Keep the window positions and overall room
proportions identical.

Style Transfer

Reference specific artistic movements:

Transform this photograph into a Bauhaus art style with geometric
shapes and primary colors, maintaining the original composition
and subject positioning

Text Editing

Describe text placement and integration:

Add the text "OPEN" as a neon sign in the window, red glowing letters
with slight reflection on the glass, matching the nighttime atmosphere
