Krea 2 prompt builder

Describe your subject, then pick the kind of image, the expression, the light and the camera. Every phrase you can pick was tested on Krea 2 Turbo on its own, and the thumbnail is its real render.

For people, write the age (“a man in his forties”). Krea 2 follows it closely, and it keeps faces from coming out generic.

The phrases call the subject

Left out, because they made no visible change in our test: “She is crying, tears running down her cheeks”; “She looks frightened, eyes wide”; “She looks exhausted, eyes half closed”.

Left out, because they made no visible change in our test: “Rembrandt lighting”.

Left out, because they made no visible change in our test: “Tilt-shift lens, miniature effect”.

Left out, because they made no visible change in our test: “Cinestill 800T film”; “Expired film with light leaks”.

How the builder writes the prompt

  • It follows the structure from our Krea 2 prompting guide: the kind of image, who or what, doing what, wearing what and where, then one sentence each for expression, light and camera.
  • Each sentence was tested on its own, added to one base scene on seeds 501 and 502 (the camera grid, the expression grid and the art style grid). The thumbnail is one of those renders. Combinations aren’t pre-rendered.
  • The tested sentences say “she” and “her”. Switch the subject to he, they or it and the builder rewrites them; expressions are skipped for “it”.
  • Phrases that made no visible change in our test are left out.
  • There is no negative prompt field, because Krea 2 Turbo ignores negatives. Say what should be there instead (“an empty street”, not “no people”). The negative prompt page has the test.
