给自己在做的一个小游戏画道具概念图，主角捡到的是一枚"数字记忆"挂坠——灰色方块、边角规整，像块被链子拴着的存储介质，上面刻着黄蓝两色的字，冷冷的科技感。想要那种一看就知道"这玩意能读取记忆"的道具语言，拍成产品特写反而更像真东西。
提示词整理成产品照的写法，材质和打光都定死：
Product photograph of a small gray rectangular digital-memory pendant, suspended by a fine metal chain. Hard-edged brushed-metal body with subtle wear, a slim engraved panel showing glowing yellow and blue text, faint circuit etching across the surface, cool futuristic tech vibe. Studio product lighting with a soft key and rim light, shallow depth of field, dark gradient background, sharp reflections on the metal, YFGFutureBlue palette, high detail, macro clarity, 8K product render.
