Your prompt

Create a 16:9 hero image for the landing page of an online bookkeeping service for freelancers, targeting independent consultants. Concept: a calm, organised desk with a laptop and a small plant, conveying control and peace of mind. Layout: a clear text zone on the left 45% of the frame (smooth, low-detail, with enough contrast for white or dark headline text); the main subject on the opposite side. The subject must also remain readable if the image is cropped to a tall 4:5 mobile crop. Look: bright, modern editorial photography, high quality, believable depth, no clutter. Colour: soft white, sage and one warm accent; keep the text zone light and even so overlay text stays legible. Constraints: no text, no logos, no UI mockups with readable text, no watermarks.

Example of what to expect

Illustrative only. It describes the kind of result this prompt aims for; real output varies by tool, model and run.

A wide image: a tidy desk and laptop at the right, a smooth light sage area at the left for a headline, and a subject that still works in a 4:5 crop.

Expected format: One 16:9 hero image; test overlay text and a 4:5 crop.

How to use it

  1. Overlay your real headline and test contrast.
  2. Check the mobile crop.
  3. Compress the final image for fast loading.

Limitations

  • Large hero images can slow a page; compress and test performance.
  • Generic stock-like imagery rarely differentiates a brand; consider real photography for key pages.

Aspect ratio is set with the size parameter, not in prose. Use medium or high quality for text and fine detail.

General notes on OpenAI GPT Image
  • OpenAI's guide covers gpt-image-2 (recommended), gpt-image-1.5, gpt-image-1 and gpt-image-1-mini.
  • Aspect ratio is set through the size parameter, not in prose. Quality is low, medium or high; medium or high is advised for small or dense text.
  • Put literal text in quotation marks, and when editing say what must stay unchanged.

FLUX.2 does not use negative prompts, so constraints are phrased as things to do.

General notes on FLUX (Black Forest Labs)
  • BFL's official guidance for FLUX.2: no negative prompts (describe what you want), write sentences rather than keyword lists, specify lighting, quote text to render, and pair colour names with hex codes.

Midjourney

Not verified: third-party guidance only · checked 2026-10-11

Append parameters after the prompt (e.g. --ar 16:9); verify parameters for your model version.

General notes on Midjourney
  • Parameters go at the end of the prompt (for example --ar for aspect ratio). Parameter names and ranges vary by model version.
  • We could not read Midjourney's official parameter list on the verification date, so check the live docs for your model version before relying on any parameter shown here.
