Techniques
Product photo shadows
A product with no shadow floats. It is the single clearest tell that an image was cut out and pasted onto a background, and it is easy to fix.
Why shadows matter more than they look
The eye uses shadows to work out where things are. A product photographed against a background with no shadow under it reads as a sticker on a page, and buyers notice without being able to say why the listing looks cheap.
A contact shadow — the soft darkening where the product meets the surface — is enough. It does not need to be long or dramatic; it needs to be in the right direction and the right softness for the light in the scene.
- Contact shadow directly under the product, tight and soft.
- Direction matching the light in the background, not the original photo.
- Softness matching the light source: bigger and softer for diffuse light.
- Opacity low — a shadow that is too dark looks like a second product.
Shooting a real one
The best shadow is the one the product actually cast. Shoot the product on a plain surface with the light to one side, and a soft shadow will fall naturally to the other. Keep it in the photo and the cut-out looks grounded without any editing.
This is also why pure white backgrounds with no shadow can look clinical: the product has nowhere to stand. A subtle shadow restores the sense of a surface.
- Light from one side so the shadow falls away from the camera.
- Keep the product in contact with the surface — no floating, no propping.
- Use a diffuse source so the shadow edge is soft.
- Avoid a second light directly opposite, which flattens the shadow out.
When the original has no shadow
Photos taken under a ceiling light, or with a flash, often have no usable shadow: it is either directly underneath and invisible, or hard and wrong. Zenith AI – Product Photo relights the product and builds the scene, which includes the shadow — placed in the direction the new background implies.
That is what stops a generated scene looking like a collage: the light on the product, the shadow beneath it and the background all agree on where the light is coming from.

FAQ
Frequently asked questions
Why does my product look pasted onto the background?
Almost always because there is no contact shadow. Without a soft shadow where the product meets the surface, the eye reads the image as two layers rather than one scene.
How do I add a shadow to a product photo?
The most convincing route is to shoot one: put the product on a plain surface with the light to one side and keep the natural shadow in the image. If the original has none, a generated scene adds one that matches the new background.
Should the main listing image have a shadow?
Yes, a subtle one. Amazon and most marketplaces allow a natural shadow on a white background, and it makes the product look grounded rather than cut out. What they do not want is a hard shadow or a reflection added artificially.
How strong should a product shadow be?
Lighter than you think. A shadow at full opacity reads as a duplicate of the product; a soft shadow at low opacity reads as a surface. Match its direction to the light in the rest of the image and its softness to the light source.
