Photoshop Playbook: Removing Objects From Images(Advanced)
如何删除图片多余内容 这话题在上期节目中讲过
In a prior episode, we talked about removing unwanted objects.
本期所展示的问题 不仅更具挑战性
Now I want to show you a little more challenging problem,
而且会把上期话题进一步升华
and take it to the next level.
那么 先来处理第一张图片
So for this first image,
使用“快速选择工具”
we’re going to use our ‘Quick Select Tool’,
来选定 需删除的区域
to select the area that we want to remove.
如果需要减少 选定区域
If we were to wander outside of the bounds,
那么 按住“Option”或者“Alt”键 用鼠标点选 来减区
we could hold ‘Option’ or ‘Alt’ to click on an area.
如果需要增加 选定区域
And if we wanted to add more,
那么 按住“Shift”键 用鼠标点选 来增区
we could hold ‘Shift’ and click on the area.
这区域 选得蛮好 虽无需增减
But that looks pretty good.
但需略做修改 适当“扩展”
What we want to do is modify that and expand it.
这张图片由于分辨率很高
And this is a pretty high res(olution) file,
因此 选定区域只需“扩展”少量像素
so I’m going to expand it quite a bit.
这下可以了
That looks good.
点击“删除”键
Now I can hit the ‘Delete’ key,
点选“内容识别”功能 (删除后不影响整体构图)
and have ‘Content Aware’ fill that in.
删除后效果不错
And it’s done a decent job,
不过,小路这头收尾 略显突兀
but the road just sort of abruptly ends.
面对这个问题 之所以首次感到棘手
And here we encounter our first trickier problem,
是因为 图片无法“透视复制”
I can’t clone in perspective.
这条路由于越靠近我 越显得宽阔
The road is getting larger as it approaches me,
因此 需要通过“透视模式”来编辑
so I need to edit in perspective.
为了解决这个问题
And to do that,
会使用“Photoshop”的一项功能 它如魔法般神奇
we’re going to use Photoshop’s little magical world,
叫做“灭点”(VanishingPoint)功能
called ‘Vanishing Point’,
该功能可设置“透视网格” (完成“透视复制”)
which allows us to place a perspective grid.
首先 沿着小路边缘(操作鼠标)
We just want to follow the contour of the road here,
以保证 生成的线条与小路轮廓相符
make sure that my lines are in parallel there.
然后 只需向我这边拖拽
And what I’m going to do, is just pull this towards me,
便形成了“透视网格”
and we can see that we’ve got a perspective grid.
我们注意到
And if we notice,
左边手
over on the left here,
有“仿制图章”工具
we have a ‘Clone Stamp’.
可以调整其 “大小(直径)”
I’ve got some size options,
“不透明度” 以及“模式”
opacity, and even healing.
而“透视复制”操作 只需
And what I’m going to do is just,
按住“Option”键 用鼠标点选 需要复制的区域
‘Option+Click’ on the area that I want to clone.
我预演下
And you see that our preview,
呈现出的效果
works in perspective.
复制下来的部分 拉远 则变小
If I were to travel back in the image, it gets smaller
拖近 则变大
forward, it gets larger.
之所以有这个效果
So what I can do,
就只是因为运用了
is just clone this out,
“透视复制”
in perspective.
“灭点”(VanishingPoint)功能 除了“透视复制”外 还能实现许多
You can do all sorts of really neat things in ‘Vanishing Point’,
非常棒的操作
cloning is just one of them.
好的 让我们退出这张图片
Okay, so let’s cancel out of that,
再探讨另一种棘手的问题
and look at another difficult situation,
无痕删除 这张图中的电线
which is removing a power line.
如果这条电线只是笔直的
Now, if this was just a straight line,
那么 用“污点修复笔刷”工具 按住“Shift”键 点击鼠标就能删除
we could ‘Shift+Click’ with our ‘Spot Healing Brush’.
使用“污点修复笔刷”工具 来处理弧线的区域
Using our ‘Spot Healing Brush’ on a curved area,
是有些困难
is a little trickier.
想想之前
And just as a reminder,
这种“笔刷”工具曾经大行其道
the way this used to work,
当时“内容识别”(ContentAware)功能还未推出
before ‘Content Aware’.
使用“笔刷” 这块区域会模糊混乱
this would get blurred or garbled.
现在很幸运 可以选择用“内容识别”功能
And luckily we have this ‘Content Aware’ option,
如果想沿着这条电线来修正
but we really want to train it along that line,
不想偏离得过多
we don’t want to wander too far off the line.
那么 为此介绍一个非常棒的办法
So I want to show you a great trick to doing that.
使用“钢笔工具”(PathTool)
We’re going to use the ‘Path Tool’.
首次 用“钢笔”光标 点击电线的一端
We’re going to click at the beginning of the power line,
再单击电线最右端
again, over on the far right,
两端形成线段 在其上再次单击
once more in between.
然后 按住“Command”键
And then holding the ‘Command’ key,
将线段拖拽 来与电线彼此契合
we’re going to pull that down, to cover the line.
两者一旦重叠了 便达到想要的效果
When we’ve got that set, just the way we want it,
我们退回
we come back,
用“污点修复笔刷”工具
to our ‘Spot Healing Brush’.
确保图片处于“内容识别”功能状态
We’d make sure it’s on ‘Content Aware’,
设置“笔刷”
and we’re going to set our brush,
按住“”Control”和“Option”键
using ‘Control+Option’,
或者是“”Control”和“Alt”键
or ‘Control+Alt’,
“大小(直径)”参数调小
to be a pretty small size.
“硬度”参数调大
And a pretty hard brush, too.
这样便可以了
That looks good.
从“图层”面板切换到“路径”面板
I’m going to come over to my ‘Path’ panel.
想去掉这根电线的“路径”
And with that path selected,
朝下看
I’m going to come down here,
这里有个选择按钮
and I’ll see that I have an option,
“用笔刷画出轨迹”
to “stroke the path with my brush”.
单击它
I click on that,
电线便神奇地消失了
and that power line just magically disappears.
为了去掉这个线段
With this path selected,
我将它删除
I can now delete it,
可以看到线段的确消失了
and see that, that line is gone.
如果电线是笔直的
Again, if it were a straight line,
那么 按住“Shift”键 点击鼠标
I could just ‘Shift+Click’,
就能从图中去掉
and that would pull it out of there.
现在你已经得知如何沿着弧线来修正
But now you know how to train it along a curved line.
你是否正尝试操作”透视复制”
So whether you’re cloning in perspective,
或者 无痕去掉电线呢?
or removing power lines,
教程介绍的这两个操作
those are a couple of great additions in your playbook,
能够大幅提升你处理图片的能力
for taking your retouching to the next level.
