CartVisualDIAGNOSTIC GUIDE / Product images
Why are there two reflections underneath my product photo?
Possible causes include reflections from more than one physical surface, an added editing layer, or a generated duplicate. A rear-coated glass mirror can produce ghost images at its glass surfaces. Compare the unretouched source, the contact point and a matte-support photograph before deciding which explanation fits your product. A virtual reflection does not establish the physical behavior of your actual support.
Start with the contact point
Edmund Optics explains how reflections at the transparent substrate of a second-surface mirror can produce ghost images. A visible double image may therefore be physically present in the original capture. First identify whether the support is front-coated, rear-coated, clear acrylic or another structure; do not assume every glossy base has the same two interfaces. Record the support and camera angle and retain the unretouched source before diagnosing an editing fault.
Locate the physical contact area, but do not use an exact contact-edge start as a universal authenticity test. A rear-coated mirror can show an offset ghost in a genuine source photograph. Compare the unretouched capture with the edit and retain support details. A second image is an observation to explain, not proof by itself of a generated or added layer.
Separate surface reflection from an added layer
Create a controlled comparison using the same camera position, focal setting, product orientation, support, and lighting. Photograph the item once on the suspected mirror or acrylic, then once on a matte surface. The matte version removes the support’s mirror contribution, but it does not by itself prove that every remaining shadow or reflection is physically accurate.
For a product that must be presented on a reflective base, photograph a clean plate of the support and inspect the lower edge at full working resolution. Keep the product’s true silhouette, contact area, and hardware visible. If an editor adds a reflection afterward, request the unretouched photograph and the edited version as separate files. External photography, retouching, and store publishing remain manual workflows; CartVisual text planning is free after sign-in, while chargeable image or video work has separate quotes.
- Compare the unretouched source with the edited or generated file before changing the surface.
- Record the product contact point and whether the support has a visible upper and lower face.
- Hold camera, product and light steady and make a comparison with a matte support, recording the changed surface.
- Review contact edges, logos and highlight alignment in both files. Obtain another physical reference or inspect the external editing layers if the second reflection is still unexplained.
Fictional exercise: two lines below a jar
In this fictional exercise, a ceramic jar photographed on a rear-coated mirror has a faint line below its stronger reflected base. The unretouched file already contains both lines. A new photograph on a matte board removes both reflections while leaving a contact shadow; the editor has not added a reflection layer. The observation supports investigating the mirror, but does not by itself identify every light path.
Keep the original mirror photograph, the matte-board comparison and the support description together. Inspect the jar’s lower rim in both files at the same size. If the duplicate persists on the matte board or appears only after editing, reopen the layer and source-file review. The exercise describes a diagnostic decision, not a measured result from an CartVisual generation.
Approve only what the evidence supports
Approve against the real product and the actual support geometry, not a universal rule that every reflection must begin exactly at the visible contact edge. Rear-surface mirror geometry can produce an offset ghost image. Use the unretouched photograph, support description and controlled comparison to assess the silhouette, contact relationship and components. If those records do not explain an important duplicate, keep it unresolved or use an approved matte-support view; do not invent hardware or erase genuine surface evidence simply to make the picture tidier.
Do not ask an image tool to restore a physically correct reflection without a reference photograph. A plausible lower image still needs comparison with the unretouched source. If the product owner cannot explain the doubled component, use the approved matte-support view or obtain another physical reference before publishing the reflective version.
Mirror, acrylic, and contact-point check matrix
| Observation | What to check | Approval condition |
|---|---|---|
| Two lower images begin at different heights | Inspect whether the support has visible thickness and whether one image floats below the contact edge | The support contribution is documented by the comparison; any unexplained interface or duplicate remains unresolved |
| Reflection follows the product but its logo is stretched differently | Compare logo, seams, ports, and silhouette with the source product | Reject or return for review if the reflection invents or changes product details |
| Lower image is visible on a matte background | Request the unretouched photograph and inspect the editing layers or handoff files | Approve only when the source evidence explains the lower image. Report an added layer only if that layer is actually identified; otherwise investigate or use an approved matte view |
| Highlight direction changes between product and reflection | Compare light position, product angle, and support angle without changing other variables | Approve only when the discrepancy is explained by the support or corrected in a new photograph |

Frequently asked questions
Can two reflections be physically real?
Yes. For example, a second-surface mirror can create a main reflection and substrate-interface ghost. Identify the actual support, retain the unretouched capture and use a controlled comparison; not every glossy acrylic base has the same construction.
Should I remove every reflection?
No. An offset is not automatically a fake reflection. Compare with the unretouched source and known support geometry. Correct an unsupported added duplicate or altered product detail only when evidence identifies it; if the cause remains unclear, use a checked matte-support photograph or reshoot.
Can CartVisual automatically fix the reflection?
Do not assume that. Use CartVisual for free text planning after sign-in and obtain separate quotes for chargeable images or video; external photography, editing, and publishing require manual workflows.
