气质OL必败轻薄卡片机 简约尼康S220评测(4)
分析测试样机的成像色彩时,我们用它在ISO 100的感光度下拍摄X-rite ColorChecker SG色彩测试标板,然后进行色彩分析,可以获得成像色彩误差及白平衡误差等数据。列表中的白平衡误差数值为中灰色块的色温误差,这项值越接近零越好,如果这项值为正数,则表示成像色调偏冷,负数反之。色彩误差图中,Lab色域坐标里的方块表示拍摄对象的理想色彩(标准色彩),圆圈则表示所测试相机的成像色彩。 以下是测试图象:

从色彩测试结果来看,尼康S220的冷色饱和度不足,而暖色中的黄色、红色系饱和度较高,致使尼康S220拍摄出来的样片色彩风格浓烈。

而尼康S220在室内混合光源下调整到自动白平衡档位拍摄的样片依旧偏黄。
