This is one mode that I have never, ever used. I’m probably not the best person to post something on it, but since I’m covering all the other blend modes I couldn’t exactly skip it. So I went to Photoshop help, as it was extremely descriptive with Difference mode, and found…

这是我从未使用过的一种模式。 我可能不是在上面发布内容的最佳人选，但是由于我涵盖了所有其他混合模式，因此我无法完全跳过它。 因此，我去了Photoshop帮助，因为它对“差异”模式具有极强的描述性，并发现…

Exclusion Mode: Creates an effect similar to but lower in contrast than the Difference mode. Blending with white inverts the base color values. Blending with black produces no change.

排除模式：创建与“差异”模式相似但对比度较低的效果。 与白色混合会反转基色值。 与黑色混合不会改变。

“Similar to but lower in contrast.” Yep, that’s the best it gets with the explanation for how it works.

“类似于但对比度较低。” 是的，这是最好的解释方式。

I came up with an example graphic to show just how “similar” these two modes are. I have two blue rectangles, overlaid with two additional layers of white/purple/black gradients. One gradient is set to Exclusion mode while the other is set to Difference mode. The overlapping part is the “result” of the blends.

我想出了一个示例图形来显示这两种模式有多么“相似”。 我有两个蓝色矩形，上面覆盖了两个附加的白色/紫色/黑色渐变层。 一个渐变设置为“排除”模式，而另一个设置为“差值”模式。 重叠部分是混合的“结果”。

Stunning similarities, aren’t there? Sorry, did I just drip some sarcasm on your keyboard? From what I can tell, blending with pure white and black in Difference Mode or Exclusion Mode produces the same result — but the middle values are quite different.

惊人的相似之处，不是吗？ 抱歉，我只是在键盘上滴了些讽刺吗？ 据我所知，在“差异模式”或“排除模式”下混合纯白色和黑色会产生相同的结果-但中间值却大不相同。

Just to confuse us even more, I created another example graphic:

为了使我们更加困惑，我创建了另一个示例图形：

Again, pure white and pure black act the same as they would in Difference Mode by kind of “inverting” the color (subtracting the color values from white, which is 255-255-255). The middle values are kind of similar as well, with a slight tint related with the blending color.

同样，纯白色和纯黑色的行为与“差异模式”中的行为相同，其方式是“反转”颜色(从白色中减去颜色值255-255-255)。 中间值也很相似，与混合色有关的淡淡的颜色。

So. Where does that leave us? Honestly, the only example of a practical application that I could fall back on was the same one as my last blog, using pure white and black shapes to create a “cutout” effect. While experimenting with Exclusion Mode did result in some interesting, weird, digital-image effects, there wasn’t anything that seemed especially useful to pass on.

所以。 那在哪里离开我们？ 老实说，我可以依靠的唯一实际应用示例是与上一个博客相同的示例，它使用纯白色和黑色形状创建了“抠图”效果。 虽然使用排除模式进行实验确实会产生一些有趣的，怪异的数字图像效果，但是没有什么特别有用的东西可以继续下去。

I’m sorry if I disappointed you — this mode was a little too exclusive for me. So as always, I welcome you to post your own experiments or links to examples of cool uses of exclusion mode!

如果让您失望了，我很抱歉–这种模式对我来说太独家了。 因此，一如既往，我欢迎您发布自己的实验或链接到排除模式酷用法示例的链接！
