• intros：{"brand_intro":"柯达（Kodak）成立于1888年，由发明家乔治·伊士曼创立，是全球胶片摄影的代名词。品牌曾垄断全球胶片市场，虽在数码时代转型缓慢，但其色彩科学积淀深厚。柯达的灰卡产品延续了胶片时代的色彩标准，采用独家染料配方，确保中性灰在日光和钨丝灯下的一致性。品控理念强调\"经典与可靠\"，每一张灰卡都经过72小时老化测试。柯达在中国市场拥有庞大的怀旧用户群，是入门级灰卡的性价比之选。","product_intro":"Professional Gray Card Plus是一款单面18%灰卡，定位入门级摄影用户。核心卖点：价格亲民，仅需89元；双面设计（一面灰卡，一面白卡）；采用哑光纸基材质，不易反光。适用于日常白平衡校准、曝光测试及手机摄影。相比德塔和爱色丽，柯达灰卡缺少色块阵列，但胜在简单实用，是摄影新手的\"第一张灰卡\"。","key_specs":{"色块数量":"1个（18%灰卡+白卡双面）","材质":"哑光纸基+防水涂层","尺寸":"20.3cm x 25.4cm","反射率精度":"±2%","适用场景":"白平衡校准、曝光测试、手机摄影","适配人群":"摄影初学者、胶片爱好者、手机摄影用户"}}
