Use exact, repeatable camera language and fixed MJ params: attach a single reference photo per SKU, state viewpoint (“front view”, “3/4 view”, “top-down”), specify lens/distance (e.g., “50mm, 1.5m, f/8”), and lock model/settings (e.g., --v 5 --ar 4:5 --stylize 0 --quality 2). Use --seed for reproducibility and only swap the SKU image/file name; keep the rest of the prompt identical.
