Prompts for Product Mockups

A mockup has a job that most generated images do not: it has to look like a photograph of a real object that exists in the world, so that whatever you place on it — a label, a screen, a print — is believed too. That means the standard is not “attractive”. The standard is “unremarkable”, and unremarkable is harder to prompt for than spectacular.

The habit worth building is to describe the shoot rather than the product. A mockup prompt reads more like a brief to a photographer than a description of a thing: what the object is, what it sits on, where the light comes from, how far away the camera is, and what the background is doing. Get those five right and the object mostly takes care of itself.

Prompt the Surface, Because That Is Where It Breaks

Believability lives in material behaviour. Matte cardboard, glossy ceramic, brushed aluminium, frosted glass, uncoated paper stock — each reflects light in a way people recognise without being able to name it, and getting it wrong is what makes an image read as fake even when the geometry is perfect. Say the material explicitly, and say its finish.

Then say what the light is doing to it. Soft box from the left with a gentle falloff gives you the neutral commercial look. A single hard source gives you strong edge definition and a crisp shadow. Diffuse overcast light gives you almost no shadow at all, which is often what you want for a clean catalogue shot. Ask for a contact shadow under the object as well — an object with no shadow floats, and floating is the fastest way to lose the illusion.

Leave the Artwork Area Blank and Flat

If your plan is to composite your own design onto the mockup afterwards, generate the object with a plain, empty surface. Ask for a blank label, an unbranded box, an off-screen or solid-colour display. Fighting a generated logo you did not want is far more work than adding your own to an empty panel.

It also helps to keep the artwork surface as close to flat-on as the shot allows. A steeply angled label is a nightmare to map your design onto later, whereas a mild three-quarter view distorts predictably. Say “front-facing”, “slight angle”, “label fully visible and undistorted” — the framing you ask for is the framing you will have to work with in a design tool.

Keep the Set Boring

Props, plants, hands, scattered coffee beans and dramatic colour gradients all pull attention away from the thing you are supposedly selling, and they multiply the number of ways the image can go wrong. A seamless backdrop, a plain surface and a single soft shadow is the mockup that gets used.

When something looks off but you cannot say why, check three things in order: the shadow direction against the stated light, the reflection on the material against its stated finish, and whether the object’s proportions match the real product. One of those three is nearly always the culprit, and each is fixable by tightening one clause rather than rewriting the whole prompt.
