Treat the Prompt as a Compact Visual Brief
Suppose you have a photograph of a yellow bicycle and another of an empty courtyard. “Blend these images” leaves several unanswered questions. Should the bicycle stand in the courtyard, should the courtyard texture cover the bicycle, or should both pictures appear side by side?
Your first job is to remove that ambiguity. Write the scene in ordinary language as though briefing an illustrator who can see the references but does not know your intention. The important information is the relationship among visible things.
Adobe's effective text-prompt guidance recommends clear, descriptive wording. That is a useful writing principle, but Firefly's model behavior and controls should not be assumed to match another service.
Use Four Parts in a Deliberate Order
1. Identify the subject
Name the object in a way that distinguishes it from other input content: “the yellow bicycle with the rear basket” is clearer than “the item.” Include the features that define the task, such as one bicycle rather than two, or the entire frame rather than a cropped wheel.
Keep preservation requests realistic. You can ask to retain the basket and frame shape, but that wording does not guarantee accurate reconstruction. If a serial number or exact logo must survive, make it a separate review requirement and consider retaining the original pixels through another workflow.
2. Assign the background
Specify which setting supplies the environment. “Use the empty courtyard as the background” tells the reader how to interpret that reference. Without this assignment, an attractive wall texture or color could become the dominant contribution instead.
Avoid asking several unrelated settings to occupy the same role unless a surreal composition is intentional. A beach, an office, and a mountain trail are not interchangeable background adjectives. Pick the actual environment before adding mood.
3. Describe placement and contact
Say where the subject sits relative to a visible feature: beside the courtyard wall, on the left side of the table, or near the doorway. Include a support relationship when relevant. “Wheels resting on the paving” is more inspectable than “perfectly integrated.”
Relative instructions are still approximate in a generative workflow. Do not treat a phrase such as “one meter from the wall” as a verified measurement. Use an editor or measured planning workflow when precise positioning is the real requirement.
4. Choose a lighting treatment
Describe the kind of light the scene should communicate, such as soft overcast daylight or a broad window source. Keep it consistent with the visible references when naturalism is the goal. If your subject already has a strong bright rim, a completely flat treatment may ask for substantial reinterpretation.
Finish with only the composition constraints that matter: leave space above the bicycle, show both wheels, or keep the doorway unobstructed. These instructions help define acceptance, even though the candidate must still be checked.
A Reusable Prompt Structure
Use this as a writing scaffold rather than special software syntax:
Place [distinct subject] from [subject reference] in [setting reference]. Position it [relationship to a visible feature]. Keep [critical visible attributes]. Use [one lighting treatment]. Leave [required empty space or framing constraint].

Three Original Prompts for Different Tasks
A bicycle in a courtyard
Place the yellow bicycle with the rear basket beside the wall in the courtyard photo. Show the whole bicycle, with both wheels resting on the paving. Use soft overcast daylight. Keep the doorway clear and leave open space above the bicycle.
Review the wheel count, frame continuity, basket, support, and doorway. The scene fails the brief if the courtyard is convincing but the bicycle has an impossible frame. This example suits a concept image; exact product or identity claims need stricter checks.
A vase on a dining table
Place the short green vase on the clear middle section of the dining table. Keep one vase with its opening visible. Use the dining-room photo as the setting, with soft light from the left window. Leave the vase empty and keep nearby tableware separate.
“Empty” eliminates an unnecessary question about flowers. “Keep nearby tableware separate” identifies an overlap to inspect. If the vase is merchandise, compare its proportions and glaze with the original, regardless of how pleasing the room looks.
A fictional reading nook
Use the bookcase photo as the room setting and place the red armchair beside it, facing slightly toward the viewer. Leave a clear walking gap in front of the chair. Use warm indoor light and keep the bookcase upright. Create a quiet editorial concept image.
This brief allows a concept rather than promising an exact interior plan. The walking gap should read clearly, but the image does not prove that the real chair fits the real room. Keep measurements outside the aesthetic prompt workflow.
Revise by Diagnosing the Failed Relationship
If the bicycle floats, revisit support and viewpoint. If the vase appears twice, make the count explicit and simplify competing references. If the room dominates, strengthen the subject's placement and framing instead of adding more praise words.
A useful revision note has three parts: what worked, what failed, and what should change. For example: “Courtyard and framing acceptable; front wheel partly missing; show both wheels fully.” Keep the accepted qualities in the brief, while recognizing that regeneration can still change them.
Do not present this process as a controlled experiment unless you actually control and record the relevant conditions. Changing one sentence makes your intention clearer, but it does not prove that any output difference was caused only by that sentence.

Compare Prompt Strategies by What They Clarify
| Strategy | What it contributes | What it cannot establish |
|---|---|---|
| Subject-only wording | Identifies the main object | Its intended setting or placement |
| Relationship-led brief | Defines the shared scene | Guaranteed geometry or fidelity |
| Long style-word list | Suggests an aesthetic direction | Resolution of conflicting instructions |
| Preservation request | States an acceptance preference | An exact lock on source content |
These are writing distinctions, not experimentally ranked prompt styles. Use the shortest brief that expresses the important relationships. Add a phrase when it resolves a specific ambiguity, not because a template suggests every prompt needs cinematic language.
Frequently Asked Questions
Should I refer to “image one” and “image two”?
You can describe input roles, but no special numbered-reference syntax was verified here. Distinct visual names such as “the yellow bicycle photo” make the instruction understandable without depending on undocumented behavior.
Are negative prompts available?
A separate negative-prompt control was not verified. Do not assume specialized syntax works. State desired conditions in the description, such as “one vase” or “empty tabletop,” and inspect whether they were followed.
Can lighting words fix incompatible photographs?
They express an intention, but they cannot establish that the source mismatch will be resolved correctly. When a candidate repeatedly changes the subject to accommodate a setting, choose a more compatible reference or use controlled compositing.
What should I save with a usable prompt?
Keep the source files, exact wording, selected ratio, candidate file, and acceptance notes. A prompt without its references leaves out much of the visual brief. These records support later review without implying identical regeneration is guaranteed.
