For a furniture finish, the surface itself may be the information. For a service that coordinates handovers between teams, the relationship may be the information. Those are different visual jobs, so “our brand always uses photography” is not enough to choose the medium for a ChatGPT ad.
Start by naming what a viewer should understand from the image. A photograph and an illustration can both be suitable, but they make different things easy to show and different things easy to imply. The choice should follow the offer’s explanatory need before it follows a preference for a particular look.
When physical detail carries the message
A photograph can show the actual appearance of a product, place or material. That may be useful when texture, construction or the arrangement of parts matters to the buying decision. For a fictional cabinet-finish sample service, a close view of the real sample can explain what the customer receives.
Check that the photograph represents the advertised item. Styling, lighting and retouching can change the impression of colour, texture or scale. A photograph is not automatically proof of every property a viewer might infer from it. It cannot, by itself, establish durability, suitability for a particular installation or a guaranteed result.
Decide which surrounding objects are necessary. A hand may help convey size. A fully decorated room may distract from the small sample actually offered. If the scene makes the offer appear larger than it is, the medium is not the only issue; the composition also needs revision.
When relationships matter more than surfaces
An illustration can make an abstract relationship visible. It might show a document passing through two review stages or a set of components fitting into a workflow. That can be more informative than a generic photograph of people in a meeting. For a service, first choose whether the image should show an activity, working material or deliverable so the medium has a defined subject to explain.
However, a diagram can still make factual claims. A line connecting two systems may imply a supported integration. An arrow skipping a step may imply that the step is unnecessary. A neatly completed sequence may suggest an outcome that the service does not guarantee.
Use the simplest relationship that the offer can support. If the service helps a team discuss responsibilities, an illustration of responsibilities being examined may fit better than a diagram showing every problem permanently resolved. The medium should clarify the real offer rather than create an idealised version of it.
Compare two rough concepts before polishing
Prepare a rough photographic direction and a rough illustrative direction using the same message brief. Describe each in a few sentences before producing finished assets. This lets the team compare the information, not just the execution quality.
For a fictional repair-booking service:
| Direction | What it could explain | What needs checking |
|---|---|---|
| Photograph of the item being inspected | The type of item and inspection setting | Whether the shown equipment and process are representative |
| Illustration of the enquiry and assessment steps | The sequence before a repair decision | Whether the sequence matches the actual service |
Neither is a universal winner. If the campaign’s question is “do you handle this kind of item?”, the photograph may be more direct. If the question is “what happens after I enquire?”, the sequence may be more relevant. Choose according to the selected question.
Do not confuse a screenshot with either substitute
For software, the actual interface may be the strongest explanatory material. A stock office photograph can hide the feature, while an illustration can show a simplified workflow that differs from the product. Consider a real screenshot when the available view makes the advertised action understandable.
Use the screenshot selection guide for that decision. The screenshot still needs review for package, state, sample data and readability. It should not be chosen simply to prove that the business has an application.
Mixed treatments can work when each element has a clear role. A product photo with a restrained diagram may explain a physical relationship. But combining media also increases the number of elements the viewer must interpret. Remove anything that does not help explain the selected proposition.
Surface or relationship?
- Material appearance
A photo can show a real sample, with colour and scale checks.
- A workflow
An illustration can explain relationships that are not physical objects.
- A software feature
A real screenshot may explain the feature better than either alternative.
Judge the small assembled version
Compare the concepts with the real headline and body copy at the display size available in your preview. Detailed textures can disappear. Fine diagram lines can become indistinct. The medium that reads well in a presentation may not explain the task in the assembled ad.
OpenAI’s campaign management documentation describes ad previewing. Use that stage to inspect appearance while retaining a separate editorial judgement about meaning. The preview does not tell you which medium will outperform another.
Record the selection as a reasoned choice: “The photograph shows the actual sample surface, which is the decision this brief addresses.” Avoid “photography feels more premium” as the only explanation when the image has an informational job.
Finally, run the visual claim audit on the chosen direction. Pair it with a concrete headline that names the same offer. The medium is doing its job when the customer can understand the intended proposition. Check that a staged scene is not presented as a real customer outcome and that neither medium invents relationships or misrepresents what is included.
