輪廓光產品照：用邊緣光做出立體
輪廓光不只服務人像——瓶身與器材也能更有電影感。
輪廓光分開主體與背景，讓深色產品在暗底仍然清晰。
主光弱、輪廓強，或相反——選一種，系列內統一。
適合耳機、酒類、深色包裝美妝。
避免雙邊輪廓一樣亮，會顯平。
Contour Light on Product: Edge Light for Dimension
Rim light separates subject from ground so dark products stay clear on dark fields.
Weak key + strong rim, or the reverse — pick one and keep the series consistent.
Fits headphones, spirits, and dark beauty packaging.
Avoid equal dual rims — they flatten form.
