选择性色彩处理

Photoshop Playbook: Selective Color Manipulation

《Photoshop教程:熟练掌握色彩处理》
《Photoshop Playbook: Selective Color Manipulation》
操作Photoshop时 时常会遭遇这样两个问题:
Two questions that I often get with photoshop are
一是:图片中物品 例如人物衬衫 如何改变颜色
“how do I change the colour of a person’s shirt or an object in the image?”
二是:如何对图片有选择地进行着色
and “how do I selectively colourise an image?”
以及 把图片局部变成黑白色
How do I make it black and white but just part of it coloured.
尽管解决两个问题很简单 但也需要掌握些小技巧
Both are really easy, but you need to know some tips and tricks.
因此 我们来看一下
So let’s take a look.
好 这里有张图片 色彩非常丰富
Alright, so here we have a really colourful image
对于这些色彩 如何进行调整 我会具体说说
and I want to talk about how we are gonna adjust those colors.
色彩调整最有效手段 是使用“色相/饱和度调整”图层
The “Hue/Saturation Adjustment” layer is a great way to do that.
该图层因为具有“无损”的特性 所以任何操作都可撤销或恢复
It’s non-destructive so anything we do here can be turned off and on.
拖动“饱和度”滑块 来增减图片饱和度
So I can pull the saturation and we can desaturate or saturate the image.
同理 也可拖动“色相”滑块
And I can pull the hue
然后 可以看到图片颜色
and you’ll see that all of the colours, in the image
会发生明显的变化
are going to change dramatically.
下面说说 色彩如何选择地进行调整
But let’s talk about how to do this selectively.
我们先把这些删除掉
Let’s just go ahead, and delete this.
小男孩衬衫的色彩 我们尝试调整一下
Let’s change the colour of my little boy’s shirt here
首先需准确地选好衬衫的区域
and to do that we are gonna start with the selection of just the shirt.
使用“快速选择工具”
I’m going to use my Quick Select Tool,
按住“Option”或者“alt”键 用鼠标除去不要的区域
and I’m going to ‘Option’ or ‘Alt’ click to deselect the area I don’t want.
这样便准确地选中了衬衫
That looks good.
返回到“色相/饱和度调整”图层
I’m gonna come back and into the same Hue Saturation Adjustment layer
会发现该图层 已创建了“图层遮罩”
and you will see that we have created a mask when we went in there.
这意味着:我们任何的操作
What that means is that anything we do,
仅仅能影响刚刚选中的区域
is only going to affect that region.
当然 这些滑块功能不受影响
And these sliders work fine
色彩有选择地调整 还有另个好办法
but there’s a much better way to do this.
这里会使用到“图像调整”工具
We are going to use this ‘On Image’ tool right here.
和这个按钮
and with it,
只需要进行点击
all we need to do is click
并且左右滑动 来增减图片饱和度
and drag left or right to saturate or desaturate the image.
更有趣的是
And where this gets really interesting
只要按住“命令键”左右拖动
is if I hold on the Command key,
就可以改变颜色
I can change the color.
随意调整下“色相”滑块
I’m changing the hue on the fly here.
好 这是我想要的颜色
So, I get the color I want
甚至还能调整
and I can even adjust
颜色的明暗对比度
the lightness of it.
经过操作 现在衬衫变成了浅蓝色
So, now it’s got a lighter blue shirt.
好了 这些操作还是非常简单的
Ok, that was pretty easy.
现在来看看 彩色与黑白之间如何变换
Now, let’s look at how to do that with black and white selectively.
好的 这里是“黑白调整”图层
Alright, so there’s a black and white adjustment layer here.
点击这个图层
I’m gonna click on that
整个图像都变成黑白两色
and the whole image is black and white.
为了去掉“黑白调整图层”的“图层遮罩”
So in order to mask off that area.
只需要按住“Option”或者“alt”键
I’m just gonna hold down my Option or Alt key
同时将这个“图层遮罩”拖上去
while dragging the mask up,
系统提醒是否替换“图层遮罩” ?按Yes键
and it’s gonna ask me if that’s what I wanna do. Yes.
看!整个图片都变成了彩色
But, we see that we’ve got the whole image in color
除了 衬衫还保持着黑白
and just the shirt in black and white.
为了达到最终效果 还需要操作“图层遮罩”功能面板
That’s alright. In doing that we also prompted this mask panel.
只要选择“反转”按钮
If I choose Invert,
想要的图像效果就呈现出来了
now I have the image I want,
通过这个功能面板 还能做些很酷的事情
and in this panel, I can do some really cool stuff.
调整“图层遮罩”的“透明度”
I can adjust the density of the mask,
只需向右拖动 “遮罩”透明度降低就能隐藏下面图片的内容
which I’ll just chew right through it to the information behind it,
也可以羽化“图层遮罩”边缘
and I can feather the edges of the mask as well
以达到图像柔化的效果
to soften the things out a little bit.
只要 应用好“图层遮罩”功能 掌握好“图像调整” 控制
So there you see that using masks and the “On Image” control,
那么 不仅能调整色彩色相与饱和度
you can adjust hue, saturation
而且 能实现彩色与黑白的切换 甚至 这些操作都是在无损的流程下轻松完成的
and even selective coloring, really quickly and easily in a non-destructive workflow.
