There is no universal number, but there is a rule: one image per doubt.
A buyer looking at a configurable product has a short list of uncertainties, and each one needs a picture. Everything past that list is decoration that slows the page down.
The usual list
- The whole thing, in the chosen finish. Non-negotiable. This is the picture that decides.
- A close-up of the material. Weave, grain, sheen. The one thing a photograph traditionally fails at and the one thing people ask to touch.
- In a room. Scale is impossible to judge from a cut-out.
- A detail that carries the price. Stitching, a hinge, an edge profile: whatever justifies costing more than the cheap one.
Four images per variant, times every variant. Which sounds impossible until you notice that they are rendered from one model rather than shot one at a time.
Where 360s earn their place
A 360 is worth it when the shape is the product: a sectional, an island, an armchair with a back worth seeing. It is not worth it for a flat-fronted wardrobe, where it costs load time and answers nothing.
