From image to campaign
Treat the generated image as your starting material.
Make room for a headline
Ask for negative space when generating the image. Add your headline afterwards in Design & Export rather than depending on generated lettering.
Choose one visual hierarchy
Keep the product or subject dominant, then use a short headline and one supporting line. Test the composition at the size people will actually see it.
Keep the source and the export
Save the generation in a project so you can return to it, change the layout and create another variation without losing the original prompt.
A starting point
A single amber bottle in the right third of the frame, warm natural light, quiet black background, generous negative space on the left, no lettering.
