Why this prompt works

Posters work from across a room, so the prompt demands a single strong focal point and high contrast.

A portrait frame with deliberate negative space is set aside for a headline.

Cluttered composition and low contrast are excluded because they kill a poster at a distance.

Using this prompt in Stable Diffusion

For a poster, Stable Diffusion is a good fit — it's known for fine-grained control through descriptor tags and a negative prompt. Promptivo formats this prompt the way Stable Diffusion expects: descriptor tags plus a dedicated negative prompt.

Paste it into Automatic1111, ComfyUI, or any Stable Diffusion host, then swap any [bracketed] tokens for your own details. Output varies by checkpoint, so adjust the tags and the negative prompt to suit the Stable Diffusion model you're running.
