Describe the scene before the finish
A useful prompt lets you check whether the output did what you asked. Name the subject, its surroundings, the framing and the light. Add visual style only when it changes the intended result. Natural sentences help explain relationships between objects.
A product image you can judge
An amber glass vase with one olive branch on a white wooden shelf. Frame it straight on with space above the branch. Soft light passes through linen curtains on the left; the wall behind it is warm gray. Quiet editorial photography with visible glass texture and no lettering.
Inspect the branch count, vase material, framing and direction of light. If the crop is wrong, change the framing instruction before adding more style words.
Make requested text explicit
A minimal exhibition poster on ivory paper. A small cobalt blue circle sits in the upper half. Below it, large dark serif lettering reads "SLOW MORNING". A smaller line beneath reads "October 2026". Center the layout and leave generous margins.
Quote the exact words and describe their position. Check spelling, punctuation and spacing in the output before using it publicly. See the publisher's prompting basics and style and text guide.
Say what changes and what stays
Open the reference editor, upload a permitted photo, then identify a single target. An edit instruction is easier to assess when it names both the change and the surrounding details you want preserved.
Change a garment's color
In image 1, change only the jacket to deep forest green. Keep the person's face, pose, trousers, background and lighting unchanged. Preserve the jacket's fabric texture and existing folds.
Examine the preserved face and background as carefully as the jacket. If the result drifts, reduce the number of simultaneous changes. The studio currently uses text instructions and references; it does not expose the publisher's bounding-box controls.
Give each reference one role
Use the ceramic vase from image 1 as the subject. Place it on the shelf shown in image 2. Borrow the muted teal and sand palette from image 3. Keep the vase's shape and glaze, and use one consistent soft light from the left.
Keep upload order stable while comparing drafts. Two conflicting subjects or two incompatible camera angles can make the instruction ambiguous. Start with two images, then add another only when you can name the detail it contributes. Up to ten references are supported, but every task does not need all ten.
Reference handling also differs across runtimes. The first image influences default shape in the official API, while our studio provides an aspect-ratio selector. See the API input guide or the publisher's multi-reference documentation.
Build a useful refinement loop
- Choose a small first output and one clear visual objective.
- Identify one concrete mismatch, such as framing, object count or a word.
- Change one instruction and compare that feature again.
- Move to a larger output after the composition works.
- Check image rights, visible errors and the final crop before publishing.
Local prompt upsampling
For local Klein workflows, keep the prompt upsampler required by the publisher. Do not assume a short raw prompt sent to local weights behaves like a hosted workflow. Follow the ComfyUI setup and upsampling instructions for your selected runtime.
These examples are original starting instructions. They are not paired with fabricated generated results or a measured success rate. The website's free allowance and provider capacity still apply when you try them.
