How to write a prompt for an AI image tool
Use this form for a still image from ChatGPT, Gemini, Midjourney, Firefly, Ideogram or a similar tool: pick New image or Edit my image at the top. For Midjourney, choose it under “Write for” in the settings card.
Why the recommended questions matter
- Kind of image. The makers advise naming the kind of image first. FLUX’s guide opens every prompt with the image type and medium, and Ideogram’s template starts the same way. Leonardo’s guide notes that without a stated style the model falls back on the style it has seen most for that subject.
- What’s in it. xAI’s guide says to write the subject first and give exact counts, and Midjourney suggests “three cats” over “cats”. Words near the start carry more weight, Ideogram says.
- Background. A real transparent background is a setting in the tools that have one, not a word in the prompt. Ideogram warns that asking for white gives a white area, not transparency, and both Ideogram and OpenAI say a drawn checkerboard is not transparency.
- Light. FLUX and xAI ask for the light’s source, direction and softness.
- Framing. Composition is part of Google’s prompt formula and of Midjourney’s list of details to consider.
Why one paragraph, and why “Avoid” is short
Most makers write their examples as plain sentences, and Google, Ideogram and Seedream’s guide say keyword lists work less well. OpenAI accepts any format. Google, Midjourney and FLUX advise describing what you want instead of what you don’t, and a 2024 study of DALL-E 3 found negation a common failure. So the form keeps exclusions to a short list of specific things.
What the form adds for you
For a new image it ends with “Avoid: text, logos, watermarks” unless you typed words for the image; OpenAI’s own examples use the same exclusions. It writes the shape as one word (square, vertical or horizontal) and puts the exact ratio in the settings card, because most tools set the shape with a control. For Midjourney it moves the ratio and the Avoid list to --ar and --no at the end, as Midjourney’s parameter list and its No page describe.
When you edit a picture
The form’s edit prompt puts the change first, then says what stays. xAI’s guide advises leading with the changes and following with one sentence that keeps the rest, and says an edit that opens with “keep everything” barely moves. OpenAI advises saying “change only X” and listing the details to preserve, and Google’s editing example tells the model not to change any other elements. If you name nothing to keep, the form asks for everything else to stay the same. An edit adds no shape and no default Avoid list.
A worked example
Lemons on a transparent background, in a 4:5 portrait shape:
Studio product photograph: two whole lemons and one lemon cut in half, showing its juicy cut face, with two fresh green lemon leaves. Dimpled, glossy peel and a few small water droplets on the peel and leaves. The subject is isolated on a fully transparent background, with no backdrop, surface, shadow or checkerboard pattern. Soft, even studio light from the upper left, with gentle highlights on the peel; bright and fresh. Bright, natural lemon yellow and leaf green; fresh and clean. The whole subject is centered with space around it, in a vertical composition. Everything sharp. Avoid: text, logos, watermarks, extra fruit, knives, cutting boards.
What not to bother with
Quality tags such as “8k, masterpiece”: FLUX’s guide says to leave them out.
