Consistent product pages make a store easier to browse. The catalog director writes the rules for angles, crops, backgrounds and file names, category by category.
Tops, bottoms, dresses and outerwear each need a set shot list. You get a table that says which shots each category gets and in what order.
The director decides where on-model photos, ghost mannequin shots and white-background images each belong, so the catalog stays coherent.
Is this for small shops too?
Yes. A 20-style shop benefits from a standard as much as a large one, and it is easier to set one up early.
Can it review my images?
It works from your descriptions. Describe what looks off and it gives the rule that fixes it.
