Build the reference before you generate the image.
Key takeaways
A reference sheet turns a vague visual preference into a set of usable production decisions. Identify which example explains the composition, which explains the light and which confirms the real product details. Label what to use from each reference and what should differ in the final work. That gives AI production a clear direction without making the reference itself the finished creative idea.
A mood board can collect images everyone likes while leaving the important decisions unresolved. One person may notice the camera angle, another the materials and another the colour. If those interpretations stay unspoken, the first generated output becomes a debate about preferences instead of a review of the brief.
Give each reference one clear job
Choose references to answer practical visual questions. A composition reference can show where the product sits in the frame. A lighting reference can show the direction and softness of the light. A verified product image can confirm the actual silhouette, label and controls. Label these roles rather than expecting the team to infer them.
Use references you have permission to use, and create an original composition around the project's own purpose. Borrowing an entire distinctive scene can make the final image feel like someone else's campaign. A useful reference describes a decision without becoming a request to reproduce everything in it.
Write down what should change
Include exclusions and differences where they matter. Perhaps the example's warm light is useful, but its saturated background conflicts with the brand. Perhaps the camera angle is right, but the real product needs more room around it. These notes are often more useful than adding another loosely related image to the board.
| Reference | Use it for | Keep separate |
|---|---|---|
| Product photograph | True shape, labels and proportions | The final scene or campaign composition |
| Lighting example | Direction, softness and shadow character | An exact copy of another campaign |
| Composition sketch | Product position and space for the headline | Decorative detail that hides the message |
| Material example | A specific surface quality | Changes to the actual product material |
Make the reference sheet work at the final crop
Sketch the product's approximate position and reserve space for the actual headline. The sketch can be rough; its job is to reveal the hierarchy. If the intended crop cuts through the feature the ad needs to show, resolve that before generating a polished scene.
- Name the subject and the specific feature or action that matters.
- Mark its position, scale and camera angle in the intended frame.
- Identify the background, material treatment and direction of light.
- Attach the product details that must remain accurate.
- Note which parts of the references are direction only and should differ.
- Purpose
Name the feature or action the scene must show.
- References
Assign a specific role to each approved example.
- Composition
Check scale, crop and copy before polishing.
- Comparison
Review the output against recorded choices.
Keep the sheet small enough to use during review. A large folder can be valuable research, but the active production reference should make the present decision easy to find. Archive earlier directions separately so an outdated example does not accidentally return in a revision.
Review the output against the decisions
Check the result in the same order the sheet describes it: subject, product accuracy, composition, light and final placement. When something is wrong, name the observed difference. “The main light now comes from the front and hides the surface texture” is a clearer revision than “make it more cinematic.”
Change the sheet when the direction changes
An output may reveal a genuine weakness in the original direction. If the team chooses a new angle, update the reference and record the reason. Otherwise the brief and the selected image disagree, and the next person may faithfully recreate a direction the team has already abandoned.
The final sheet should explain what the asset is doing, not just what the team liked. Keeping that reasoning alongside the export makes a later crop, motion treatment or companion asset easier to produce consistently.
Putting it into practice
- Label the job of each reference.
- Resolve hierarchy and crop before polishing the image.
- Keep the reference sheet aligned with the approved direction.
Frequently asked questions
Does the reference sheet need to look like a finished design?
No. A simple annotated layout can resolve the important choices. It needs to make the subject, framing, light and required product details clear enough for another person to review.
How many references should be included?
Include the references needed to answer the active visual questions. Remove examples that repeat the same role or introduce a direction the team has not chosen. Clarity matters more than the size of the board.
What if the generated output suggests a better direction?
Review the proposed change against the message and product constraints. If the team approves it, update the reference sheet and explain the choice so later production starts from the current direction.
