類比顆粒浪潮：用底片感建立溫度
輕漏光、柔和色偏與細顆粒——讓數位內容看起來「被時間摸過」。
類比風不是把對比拉垮。關鍵是：細顆粒、輕微色偏（玫瑰灰／舊青）、偶發漏光，並保留足夠中間調，讓產品仍可辨識。
適合咖啡、旅遊、生活方式與敘事型品牌。電商主圖若需要清楚規格，可用「情境類比 + 白底規格照」雙軌。
後期建議用真實掃描顆粒疊加，透明度 10–25%；漏光放在邊角，不要蓋住主體臉或 logo 區。
這波趨勢在歐美社群廣告很常見——它對抗的是過度 HDR 與塑料磨皮，追求「人味」與信任感。
Analog Grain Wave: Film Texture That Adds Warmth
Analog isn’t crushed contrast. Aim for fine grain, a soft cast (dusty rose / faded teal), occasional light leaks, and enough midtones that the product stays readable.
Fits coffee, travel, lifestyle, and story-led brands. If ecommerce needs clean specs, run dual tracks: analog context + white-bg product.
In post, overlay real scanned grain at 10–25% opacity; park leaks in corners — never over faces or logo zones.
This wave is common in Western social ads — a pushback against HDR gloss and plastic skin, chasing human warmth and trust.
