How to write a great GPT Image 2.5 prompt

Lead with the subject

Say who or what the image is about and what is happening before you describe style. The first details carry the most weight.

Describe light, lens, and mood

Lighting, camera distance, and atmosphere change an image more than adjectives like stunning or beautiful.

Quote any text you need

Put words that must appear in the image inside double quotes and say where they go, for example a headline at the top.

Model tip

GPT Image 2 follows long, detailed instructions closely, so spell out layout and text placement.
