你没说清楚 我来帮你说清楚 先说“通道混合器” 这个工具直接对通道进行编辑 结构分为 “输出通道”和“源通道”如果 输出通道是红色 在源通道里面的蓝色上添加红色 操作就是把蓝色通道的滑块向左拖动 结果是 画面上的蓝色变成了洋红 如果输出通道是蓝色 源通道是红色 结果是红色变成了洋红 再说“可选颜色” 里面能够调节的通道只有 洋红 黄色 青色 所以不能在蓝色通道上添加红色 而红色是由黄 洋红构成的 如果在蓝色通道里添加 黄 洋红 结果并不能使蓝色变成洋红 你可以试试

  1. 蓝色里加红就是两种颜色混合后形成的颜色,结果无非是品红、紫红和紫,至于是那种颜色要看蓝和红的浓度比例了,各站一半就是品红了。

  2. 通道混合器可就不是这个概念了,还是这个题,在蓝色通道里加红,扩展一下,再来个加绿,是什么概念?为了解释清楚,必须来个具体值,比如某处颜色RGB值(50,200,100),此时在蓝色通道里加红10%,此时蓝色值为:100(原蓝值)+50(原红值)*10%=105,其它值不变,即此时RGB值(50,200,105);如果继续在蓝色通道里加绿20%,此时蓝色值为105(蓝里加红10%后的蓝值)+200(原绿值)*20%=145,即此时RGB值(50,200,145)。以上可以看出,通道混合器蓝色通道无论加绿还是红,只是蓝值在变,其它颜色不变,其它通道道理一样,不知说明白没有?

  3. 通道混合器通常可用来调节照片白平衡,以弥补拍照时白平衡选择的失误。

回答3:

这2个命令,“可选颜色”中有红、绿、蓝、青、洋红、黄、黑、白、中性灰,好多的颜色可调的啊,而“通道混合器”中呢,只能调节红、绿、蓝这3色。相比起来,初学者都知道是可选颜色的常用啊,比“通道混合器”的好用多了。 可选颜色在使用时,涉及到一些颜色原理知识的,你学过的话,就能很好的玩转它了。

回答4:

改变颜色 和改变通道 效果不同 蓝色里加红而已 通道 蓝色通道 红色部分提亮 就不同 主要看效果 逻辑的东西没必要 毕竟图片千变万化 包括图层混合模式 也很复杂
