气球字母 JOY

一张欢快的产品级字体排版图，单词 "JOY" 由三只约一米高的充气铝箔气球字母组成，并排悬浮在柔和奶油黄色摄影棚背景前。J 为糖果粉，O 为薄荷绿，Y 为天蓝，均带有真实的乳胶接缝、打结点和受光时可见的充气褶皱。每只气球底部都拖着一条细白丝带。相机正面齐胸高度，模拟 85mm f/5.6 镜头，气球细节锐利，无缝背景柔顺渐变。左上方大柔光箱提供宽柔高光，右侧反光板补光让阴影呈珍珠灰。地面隐约有彩色光晕。"JOY" 三字间距均匀，清晰可读，无额外文字、彩纸、人物或品牌标识。情绪欢庆轻盈，像高端生日品牌的广告。

A cheerful product-shot style typography image showing the single word "JOY" formed by three inflated mylar balloon letters, each about one meter tall, hovering side by side against a soft butter-yellow studio backdrop. The J is candy pink, the O is mint green, the Y is sky blue, all with realistic latex seams, knot points, and visible inflation creases catching the light. Each balloon has a tiny white silk ribbon trailing down from its base. Camera is straight-on at chest height, simulating an 85mm lens at f/5.6, so the balloons are crisply detailed and the cyclorama curve behind them falls into a clean creamy gradient. Lighting comes from a large softbox at the upper left producing wide soft highlights on the rounded shoulders of each letter, with a subtle bounce card on the right keeping shadows pearly. Faint colored light spills onto the floor below, hinting at the balloons' tints. The letters should read perfectly legible, evenly spaced, no extra text, no confetti, no people, no brand markings. Mood is celebratory, light, and tactile, like a high-end birthday brand campaign.
