Pick a prompt by output, not by aesthetic label

“Cinematic” or “beautiful” does not define a usable asset. Start with the job: a hero with text space, a faithful product scene or an editorial metaphor. Each prompt above names the input you need and the reason to reject a result.

Keep a small experiment log

Version One variable changed Result Decision
A Baseline prompt Subject correct; text zone busy Revise
B Simpler background Text zone clear Keep
C Warmer light Product color shifted Reject

Save the prompt with the image. A visual result without its instructions is difficult to reproduce, review or improve.

How long should an AI image prompt be?

Long enough to define the visible decisions that matter. A concise prompt with placement, subject, composition and constraints is more useful than a dense list of style adjectives.
