01
Freeze the form for the comparison
Identify the lamp concept and file version that every finish view should use. Record the views needed, such as a full object view and a closer look at the shade. Keep the object placement and viewing setup consistent across the proposed finishes so that reviewers are not responding to a different composition in each image. If someone changes the proportions, treat that as a separate comparison. The brief should make it easy to answer a basic question later: were these images intended to compare the same form, or different object concepts?
02
Describe the surface without inventing its performance
For each option, record the intended colour, visible texture and reference material supplied to the person producing the images. Distinguish an approved sample from a rough visual reference. In the lamp example, a brushed-metal appearance might be an aesthetic direction while the actual manufacturing material remains undecided. Do not let a rendered sheen stand in for evidence about durability, heat behaviour or finish consistency. Keep those material questions in a separate list for appropriate supplier information, physical samples or later assessment. The image can communicate an intention while leaving those questions honestly open.
03
Ask for a decision the images can support
Frame the review around the intended visual question, such as which proposed finish best suits the collection being developed. Invite reviewers to point to a particular view and explain their response, rather than recording only a preferred option number. Preserve the selected image version and the unresolved questions alongside the decision. If the team wants to know how the actual surface looks under its intended lighting, note that as a physical-sample follow-up. This keeps the visual review useful while making the next development step explicit and traceable.
