Use Direct Path Selection Tools
用直接选择工具
选择工具包含？钢笔工具 直接选择工具 路径选择工具。路径选择工具是黑箭头标识的，目标展示给你路径。钢笔工具热键P，星号提示创建新路径。选择路径如果需要进一步编辑，先选中，选择工具才能发挥作用。选择部分区域即可，不需要选择全部。黑色箭头代表非建设路径的工作状态，不管你点击多少次字幕框选工具，会得到整个路径，如果去选择，点击回车，注意路径面板，提示没有被选择的图层路径了。there're essential components when deal with pen tool. direct selection tool, path selection tool. the path selection tool is the black arrow, its only purpose is to show your path. if we grab pen tool. you'll notice asterisk symbol next to it, this means we're about to create new path. i want to further dit existing one. that's why i select it. that's where path selection tool comes into play. just cover a tiny bit is enough. that's because this tool doesn't target individual anchor points.
所以不管尝试多少次黑箭头，不处于工作状态。所以需要点击图层面板，展示轮廓线，可以从画布选取。利用钢笔工具。切换到钢笔工具，可以加入锚定点，可以移除锚定点，可以进一步调节。附加线条可以创建曲率，控制柄可以调节曲率。所以直接选择工具可以选择路径上单个锚定点，用shift+A在两工具间切换。用回车键去选择或从图层面板点击去选择。no matter what you click on how much you marquee on it, you'll get the entire path. when you want to deselect, hit enter, notice the path panel. you no longer have it selected there. so even though you may try to use your black arrow. it's not going to work you need to click panel layer and reveal its outline, you can grab it from canvas. i can switch back to my pen tool, and i can add anchor points, or i can remove them or further manipulate. what's up with additional lines that show up when you create a curve. these are called control handles. and through then you can adjust your curvature. you have to first select individual anchor points. we've established black arrow, gets the whole path, no matter where you click, that leaves job up to white arrow. so the direct selection tool helps you select individual anchor points from a path. hotkey A you can cycle between them by using shift+A. i'll deselect it with enter or click on path from panel.
用白色箭头可以看到路径轮廓线，在该区域绘制小盒子，仅仅选择点，被选中点黑色实心的，没被选中点空心的。取决于灵活性的程度。如果选择移动，向上移动时，其它手柄带动朝相反方向移动。这就是如何进行真的项目，点击一次，如果不是你想要的。按住Ctrl可以开始反复调节。按住Ctrl不松手，可以通过手柄调节曲率，可以替换体现新变化的锚定点，调节手柄到曲线平滑，锚定点越少，路径越平滑。we see its outline now with white arrow. i'll draw a tiny box in this region, only this point selected. compare it with all others are hollow this is filled with black. you click on it, you can move it about as you move it upwards, the other hand is going to move in the opposite direction. here's how this would go on a real project. you click one, this isn't way you wanted it, you hold control and you start fine tuning things. i can fiddle around with handles to adjust curvature while still holding control. i can reposition any anchor point this entails new changes. i'll grab handles again what you look for in parts in smoothness. the less anchor points the better your path is going to look.
最后关于钢笔工具，从草图开始讲起，拖拽手柄找下一个点行进到方向。意味着可以点击空白区域设定目标方向，但是曲折的路线不满意的。按住Alt延伸向行进路线，各种可能性。one final thing about pen tool is this, let me start from scratch. when you click and drag, the handle here will determine direction of next point, that means that if i want to click somewhere in this region, i'm going to end up with something that looks like this. that's not ideal. if you want to go towards direction, hold down Alt and grab this handle. how if you click in that area, this is going to be more in line with your goals, there's a world of possibilities, that's available to you through pen tool.

Activity Pen Tool Selections
钢笔工具的选择
PSD有很多形状。如果我们直接选择另外的方向，需要很多条件。按住Shift直线数秒，点击中点没问题，一段段的重复点击拉伸动作到对面。如果点击最后，不能完美的拉直选项，可以向内切到内容，意味我们形状上失去一两个像素，总好过外面包绕没清理干净的白边。从左侧顶部单独点击开始，移动下来点击区域任意点，开始改变形状，延伸到附近区域另一个锚定点，中间可以找到折中点。we have lots of shapes in this PSD, please download it and follow my lead. i'll do a couple and then i'll pass the torch to you. this is how you truly master pen tool by working in various situations one after another. because it only requires straight lines for second point, i'll hold shift, this will create a perfectly line, even though i'll click somewhere inside shape, as you can see, no problems with it click on middle point, now repeat process on the other side. if yet me go through these last clicks, in these situations, if you can't line up selection perfectly with shape edge, i'd rather you have it placed inwards, this means we lose one or two pixels from shape. this is much better than having a white stroke all around it from BG. start from the top left with a single click, now move down and click somewhere around region, before object starts to chagne its shape, we aim for another anchor point near this area, because around here we can find its middle point.
如果我们直接拖拽到另一边，给予各种调节，点击拖拽到另一侧。可以匹配曲率。调节边缘，替代白色的像素。最好按Ctrl切到黄色内部。下个完美的直线，如果点击不通过任何调节热键，而是单纯的拖动，可以用Alt点击锚定点，得到完美的线条。右侧和底部的类似，可以移动远一点，手柄完善路径的关键，不用恐惧移动锚定点点位置。圈回来，关闭路径。if we drag directly on the other side that would require a lot of fiddling, click and drag directly on the other side, that would require a lot of fiddling, so click and drag towards right. we have pretty far out to match curvature, i adjust its edge, instead of getting any white pixels, i'd rather cut a bit into yellow thingn here, use ctrl drag right handle inwards. on the next line it should be perfect straight. if we click without any modifier key which will require a bit of fine tuning, instead i use Alt and i'll click on anchor point, i'll get a perfect line. this right side is similar to what we didi in bottom, i'll move a bit faster through it, these handles are keys to great path. don't afraid of changing anchor point placement. i'll circle back and look for this symbol so i can close off my path.
从部位的两个颜色交叉部开始，点击移动到目标侧直线中点，点击拖拽右侧，放大缩小可以找到合适观察角度。移动到钢笔工具，检查你的路径是否物体边缘。尽量用手柄选择居中。这需要拖拽。start from outer part from this place where two colors intersect. click once and now move mouse over to imaginary middle point of shape, click and drag towards right. switch to zoom tool to get a better view. and move back to pen tool. check if your path is flush with object edge, i'll try to postition next anchor point a bit further a way from this one. it's also going to require concentration we can handle it. this needs a lot of dragging, but it's looking great.
注意前的点，如果你需要进一步通过Ctrl调节手柄，你可以移走不需要的白色像素。不能依赖转向点工具，因为事情需要继续平滑线。当你在两点间调节，或者直接拉伸向目标点。在合适的视角需要调节，如果太近，可以能影响调节手柄，但是可以返回继续。调节完善，用Ctrl调节每个锚定点，最后一次依据需求调节手柄。pay attention to previous point, you might need to further adjust their handles with control key. you can remove unwanted white pixels. we can't rely on convert point tool, because everything needs to be one continuous smooth line. when you play it safe, at another point in between these two,, or do you go directly for end. it's better in my view, it's going to reauire a lot of fiddling, if you're too zoomed in your image might move as you drag this handle, we can go back. just to be sure everything is fine, is to contrl click each anchor point and adjust handles one last time in case it's needed.

Quick Mask Mode
快速蒙版模式
用特殊的方式检测选择和进一步调节。可以构建建筑顶部蓝色的，天空也是蓝色的，可能选择屋顶蓝色也选中天空颜色了。所以这是个需要解决的问题。我们用快速蒙版模式证明对于解决该问题无效。用快速选择工具，可以在底部大胆涂抹，但是顶部接近天空的时候越是小心翼翼，避免选择屋顶的时候选择天空。蓝色帮助非常有帮助的。用Q快速选择工具。如果图层现在高亮红色。明显看到红色天空和红色屋顶的重叠。快速选择给到可选择的视觉化呈现，某种情况建筑的被影响没有被选中的区域。a particular helpful way to check quality of selection and further modifying them. we have building its top edge is blue, our sky is blue as well so that might throw off selection tools. that's bound to be a problem. i'm going to use it to demostrate usefulness of quick mask mode, in this case, i'd rather use one of lasso or better yet pen tool i'll go with a suppar choice for job. quick selection tool. i paint over buildings like so. you see it doesn pretty good job in bottom of middle area, as i go towards top. things aren't hot because i'm afraid to go over region because i'll get the sky in my selection, which is exactly what i'm trying to avoid. this blue on blue isn't helpful. it comes the quick mask mode by the way of its hotkey is Q. our layer is now highlighted in red, even more striking is this red overly that covers our sky. quick mask mode give you a better visual representation of what selected in this case the building which is unaffected and what's not selected, sky and what's covered in red.
可以放大看问题区域，展示各种选择问题。可以用解决方案，B刷子工具，白色前景刷，涂抹红色区域，红色房顶证明未被选中的房顶区域。现在我想整栋楼包括房顶全部选中。调节刷子需要的硬度。尽可能的绘制完整。最好的方式用钢笔工具，点击几次。我们不需要特殊区域的曲率。关闭，右键选择。允许快速选择模式。要么往里面切入，要么一些白边，都要先展示楼层全貌。退出快速选择模式用热键Q或按工具栏的徽标，一旦选择步骤完成，可以进行下一步工作。i can zoom in and focus on problem areas, besides showcasing all selection issues. i also get a great way of solving them. grab B brush tool now with white as my foreground color, i can start to paint over these red areas, red means it's not selected and i want entire building selected. adjust your hardness if needed and do your best to paint over areas. a much better approach would be follwing. get the pen tool and quickly click a few times. we don't need any curves for specific region. close it off and right click and make a selection. that's allowed in quick mask mode. once we have you can either paint with a brush inside it or better yet use Alt delete to fill it with white. that means we'll reveal this building. which in this case translates into a selection take care of right side, if you have few moment to spare. let's ay our work is complete. exit quick mask mode, either through hotkey Q or by pressing on icon in tool box. once you do that, you're left with a nice selection and you can do whatever you want.
快速选择工具很容易应用，用Alt移除部分误选进来的。但是套索多边形或钢笔工具是更好的选择。用快速选择工具练习，比如目标去除天空，也是训练选择技巧的帮助。楼层占据80%照片，如果选择天空，活动区域更小，更困难，未必适合快速选择工具。even though the quick selection tool is easy to use, it wasn't best tool for job. i could have used Alt to remove parts of sky if they've been selected by mistake, but polygonal lasso po pen tool would have been much better options. further more, the whole exerciese is based around a goal, to show you quick mask mode, if that want's case tand i wanted to get rid of sky, i would have have approached it the other way around. instead of selecting building, which is what 80% of photo, i would have selected sky, so my point is to always work smarter, not harder even though you maybe comfortable with some tools, they may not be appropriate for task at hand.

Select A Color in Photo
选择图片中的颜色
从图片中选择颜色比较艰巨的任务，预计10分钟搞定。可以从选择开始，敲定编辑点，魔术棒或快速选择工具，需要多次点击因为图片有很多细节。这加速的过程，到主菜单点击选择，颜色范围。下拉菜单设置为样本颜色。但是可以改为红色。在小的预设窗口，都是白色被选中的，选择红色，效果欠佳。高亮模式给选中更好的花朵，但是如果左侧顶部，你可以看到选中一点天空。flow to select a color from a difficult image with the least amount of work possible this allow you to cut down the time it takes to select all flowers from photos, set aside about to 10 minutes for task. you'd first have to start with a selection so you'd first have to start with a selection so you could pinpoint your edits, magic wand or quick selection tool might do the job but that require a lot of clicking because this photo has so many details. here's how we're going to proceed. go to top menu and click on select now choose a color range. first dropwdown is currently set at sample colors, but i can change it to red's . in the small preview window, everything that is white will be selected, we can see the red option isn't doing a fantastic job. this would give us more of these flowers. but if you look at top left corner. you can see we're also getting a bit of sky.
样本颜色模式从画布选择，光标停留在图片上方，变成拾色器颜色，可以取得样本，点击天空，你可以在预览中看到少量天空色，说明这模式效果相对好一些。底部区域为灰色，选择展示直接展示画布底色，再次点击花朵部分，调节选区。下面是保存按钮。拾色器是目前用的，另外两个工具，可以通过添加或移除的选区。偏好选择Alt移除Shift添加热键。如果你不喜欢点击一次选择所有花朵，可以按shift点击几次选择花朵。可以重复过程，按住shift多点击几次，看到预览区被选花增长。this creates a selection based on what colors we grab from the canvas. you can see that as i move cursor over my image, it turns into eyedropper tool. this means i'm about to sample this color let's click over the sky so you can see how this works. this preview shows me now i have now selected the sky, but it's a tiny window that makes it hard to see if you're doing a good job. we'll focus is bottom area and click on this dropdown, choose grayscal,e and this will now show you the preview directly on the canvas. click again some where, over the flower, this adjust your selection. underneath the save button, we have three tools, the eyedropper, which i've used so far, and two other eyedropper tools through which you can add or remove parts of selection. i prefer to use hotkeys shift to add, alt to move. it's unlikely you'll get all these flowers with one click that means i'll have to slowly build up selection by clicking several times. while holding down shift key. let's do that now by change preview to grayscale yet again. click on any flower, then repeate the process several times while using the shift key notice how my selection is starting to grow.
模糊滑块，为了进一步调节，模糊功能像写入了生命力。上调到150，可以看清楚图像的内容。一旦掌握诀窍会短时间选中花朵，而不是选错工具。如果选择花朵太多了，按Alt去掉选择工具。如果勾选“局部色簇”获得范围特征的调节入口。用于控制包含在选择区内的信息。增加的越多，ps需要查询的区域越大。to further refine it, this fuzziness slider is a lifesaver, turn it up to about 150, you'll see how you get a uch clear image of what's going on. once you get the hange of it, the whole process will require significantly less effort than selecting each flower individually with any other selection tool. this is way too much, but it helps you identify those areas that need to be excluded, hold Alt and start clicking on this grey, constantly switch between adding to your selection with shift and removing parts of it with help of Alt key. if you select localized color clusters, you'll get access to this range feature. use it to control what's going to be included in the selection based on the area where you click, the more you increase it, the larger of area ps will look at. so this is helpful if you want to focus ps attention on particular spot.
保存下载AXT文件，可以打开已经保存在本地的AXT文件，如果看到蚂蚁行军的选区，这就是选择工具的效果。加入曲线调节图层，可以把中间点拖拽到下面，可以增强黑色区域，因为我选区是活跃的，可以看到蒙版仅仅影响选区内的花，非选区的不影响。what's great is that we can save our work and we can come back to it another time. so let me click load this will prompt you to select a dot AXT file. i double click it. now i have it available in PS. once you see marching ants, you can see it did a great job far better than quick selection tool could offer. add curves adjustment layer from the bottom of my layer's panel. now i'll drag this middle point downwards. so i can intensity my darker regions. because i had a selection active, you can see my mask reflect the time only affecting my pink flowers.

Activity Remove Background
移除背景
展示如何从背景移除球。这是末尾结果呈现的样子，大概15分钟时间。四个步骤？ 第一，移除背景。第二，通过调节图层添加新的背景；第三，创建真实的阴影；第四，创建贴图。创建选区？钢笔工具是首选，但是因为人们选择快速选择工具，抓取并且鼓励，停留在上方，底部工作效果并不好。因为阴影和草丛混合在一起。按Alt移除不想要的区域，但是仍旧不到位，然而，球体的弧度是选中了。i'll show you how to remove football from background, here's what end result is going to look like, this take you roughly 15 minutes. one remove the background, two add a new one through an adjustment layer, three, create a realistic shadow, four, create a vignette effect. the pen tool would be my first choice, but since a lot of people use quick selection tool. i'll grab that instead. i'll go over it and you'll see this isn't doing a great job at the bottom, because the shadow kind of blends with the grass. i can hold Alt to remove those unwanted spots, but it's still not going in right direciton. nevertheless, the bulk of work is done.
我们开始清理掉多余的像素，因为我们可持续修复的工作，所以球被放在透明背景里。剪切并非完美。因为我们用的图层蒙版，可以进一步剪切。现在可补救性的选择绘制靠近球体边缘，这不会太迅速，也不会得到太理想的结果。但是足以证明我的建议值得一试。我建议用钢笔工具，从左侧开始勾选，通过三笔来勾选球体表面，选择附近中间部位，有了帮助定位的橡胶体。开始朝着右侧拖拽，得到完美曲线，如果移除一小段橡胶不用担心，不影响整个设计。点击右侧区域，取决于如何放置前面点，用Contrl进一步调整，用Ctrl Z重新设计路线。现在右键选择羽化直径设为0像素，确保保持抗曲折复选框勾选，该情况是需要保持平滑的。黑色前景刷子移除掉不想要的点。we're doing that instead of deleting all these pixels because we want to work non destructively. here's football on transparent background. not quite a perfect cut out. but because we're using a layer mask, we can further work on it. now if you want the alternative, grab a black brush, zoom in and startign painting, go over each area and slowly get closer to bulls edge, this won't be fast, nor will it give you a great result, but it's foolproof, i suggest you do it my way. now we've avoided the pen tool, but here's the best option for the job, let's start from the left side, i want to get this entire bottom half with just three clicks. this will ensure a perfect smooth surface, i'll click on its left edge. next, i'll go somewhere near its middle point here, and the great thing it is that we have this rubber part that helps me position my click correctly. i'll drag a lot towards the right side, so i can get a nice curve, don't worry if you remove a smart part of it, as long as it's just a few pixels this won't affect our fine design. let's click again on the right side, depending on how well you placed your previousl point, you may need to use control to further adjust it. in case it's not going well at all. use Ctrl Z and retrace your steps. now i'll circle back around with a few quick clicks their position doesn't mater, because it won't impact my selection. now right click and choose make selection leave the feather radius set zero pixels. but make sure you have anti alias check, in these cases it's much needed. now paint with a black brush to remove all unwanted bits.
热键Ctrl Alt Delete给选区填充黑色。提到的两个热键取决于色素板，创建的背景在调节图层实体颜色，用喜欢的颜色填充背景，调节图层实体颜色不包含任何实体像素，仅仅调节已经存在的。点击后回到顶部，顶部有实色选项，和纹理 梯度在一个区域内。我选择好看的蓝色，比如80AFFFF在图层下面，这种情况背景移除掉实色，可以暴露问题，用刷子补救缺失掉的颜色。you can use Ctrl Alt Delete to fill that area with black, i mentioned both hotkeys because it depends on what's swatch you have on top in your tool box, we're all set. now let's create a background for it with the help of an adjustment layer solid color will fill our canvas with any colro of our liking. note that adjustment layers. in general, don't contain any actual pixels. they only modify existing ones. click here and go all the way to the top. this is what you're looking for solid color, which is one of the exceptions alongside gradient and pattern. i'll go for a nice shade of blue. let's say 80AFFF place it underneath our layer, in case you have any issues with your background removal, this solid color will expose any problems, if that's the case, click on your mask and brush over any spots you may have missed.
开始创建阴影，避免球体像是漂浮在空气中，需要展示出阴影深度，点击拖拽阴影层。目前预设阴影位置球体下方，大小2/3大小，不偏不倚。点击形状转化成智能对象，选择 模糊 高斯模糊，设置50像素模糊。热键G创建真实的梯度工具，选择放射梯度，按住shift透明转化，如果阴影太小显得不够平滑，如果阴影偏移并不理想，重复按住直到看起来阴影不偏不倚。曲线调节，曲线拖拽到中间，确保刷子50%硬度，很大刷子，移除球体周边没必要效果。let's create a shadow, so it won't seem like it's floating in space, grab ellipse tool from tool bar, even though we haven't covered it in depth so far, click and drag to create a shape like this. so fairly squish at about 2/3 of the footballs length, position it underneath the ball and center horizontally, this is all set click your shape and convert it to a smart object. this is so we can adjust upcomging filter apply a blur, specifically a gaussian blur, use the top menu for that, from the window, put in a value of about 50 pixiels hit okay. we're going to get the gradient ool, wich has the hotkey G. hit D to restore your default background foreground color. you're looking for this preview here, the gradient top has multiple ways of working we want a radial gradient. you're lookign for a smooth transition on the side of the shadow, if you don't hold shift, you won't drag in a perfectly straight line, you might end up with something uncentered shadow. if you swipe too little, you're going to end up with a tiny shadow that is not smooth. if you don't get it right swipe again and you'll reset your gradient, so repeat your swipe until you end up with somehting that looks like that.it's darken the corners of canvas. and adjustment there at the top of layer stack, choose curves from properties panel. drag this one down somewhere near the middle, this darken everything. let's say hardness somewhere around 50% and will remove the effect on and around the ball. make sure you have a huge brush, i'm going for something well over 2000. click on ball and brush in circular pattern.
84.06-8.9
Select And Mask Hair
选择头发蒙版
该图像移除背景替换成维持模特头发细节。选择快速选择选中女模特。可以看到空中凌乱的头发吐出来，目标移除背景。保留空中发丝，用PS新功能选择和遮蔽，旧版本叫做修复边缘。在选项区可以找到，点击任意选择工具，可以调取选项栏的按钮。用Alt Ctrl R 热键组合工作区变了，左侧少数5个工作图标，从上到下依次是，第一，快速选择工具，可以抓取局部聚焦点；第二，调节边缘刷子，正常刷子；第三，套索工具和磁性工具；第四，抓手；第五，放大缩小工具。we'll take this image, remove its background and replace it with this one, all while maintaining the detail in model's hair. so i use quick selection tool to roughly select girl. apparently it did a great job. if you focus on hair you can see there're few strands left out, the goal is to get there back with minimal effort luckily, PS give us completely new workspace called select and mask, that helps us improve our selection, in previous releases of ps was called refine edges. if you don't have this button available in your options bar, grab any selection tool that creates selections will give you this feature. alternative you can use hotkey Alt Control R once i click it, my workspace changes here, on the left side, you see we only have few tools. if one of the more powerful ones in ps is quick selection tool. this is useful in case you forget to grab a spot or region. refine edge brush which will use in a second a normal brush. the lasso tool, magnetic tool, hand zoom tools.
右侧的都是特征和设置的集合。有些在处理头发的情况下可用有些不可用。预览模式，可以不同背景看人物。调节预览模式不透明度可以深得要领。列表中没有最好的背景图。目标是，最好的选择，现在是挖掘问题的时间段。用预览重叠模式因为红色展示很多问题。直径滑块帮助拓展选区的。帮助挖掘遗留细节的。如果提高直径大小，250像素最大值，可以看到默认的原始背景导致缩小白色点。the right side is packed full of settings and features. some of the more important than others in this case, where we're dealing with hair, the view mode is one of the most interesting ones, because we get to see our selection in various mode, what's great is that you can opacity of your viewing mode so that you can get a better grasp of what's going on this. there's no particular one from this list that's best for all cases. you'll have to go through them and see the selection at its worst, not at its best. and that's because now is the time to correct any potential problems. i'll use overlay as my viewing mode because this red showcases all my issues that radius slider helps us expand your selection region, this usually picks up on small details that have been left out. if i crank radius to its maximum value, 250 pixels. we can see it did a decent job at eliminating those white spots caused by original background.
当处理头发模糊时或类似材质，通过“智能直径”的开启，可以看到丢失其它细节。头发模糊的这不是我们要的结果。如果不确定你需要用的数据，面板顶部勾选“展示边缘”功能，通过开启，可以看到PS寻找的额外的头发，滑动“展示边缘”为零，可以看到很多。但是如果逐渐增加，可以看到头发边缘外头发范围捕获越来越多。“平滑+羽化”这两个设置不适合开启，应该避免清理头发，我们保留细节的，清理细节的两个功能无用武之地。所以不开启。when you're dealign with hair fur or any similar texture, by turning smart radius on. and we can see how we're gettign back some important details which would have otherwise lost. so you can see the difference after toggle smart radius on and off a few times. so without smart radius this body of hair becomes translucent that's less than ideal. if you're not sure what value you need to use, go to the top and check show edge freature, by enableing it, you can see the area that ps iwll look for extra hairs if the show edges zero. you would see anything.but as i slowly increased it, you can see how this region grows. smooth feather are two settings you should avoid when clearing with hair. they have no place here because we want to get all these fine details in our end result, whereas these two eliminate all extra fine parts.
不确定对比功能是否用的上，就做做实验。让头发边缘更锐利更可见，在0%到100%之间滑动看效果，所以你看到的不同。但是不需要这些功能，略过。按Ctrl+0可以图像适配到屏幕。选择更好的方式暴露不够贴服头发丝，才可以目标明确的修剪掉。因为目前还没修剪，目前暴露问题阶段。滑动“转化边缘”刷头发边缘，细节头发可以刷回来，但是白色背景也刷回来了。这就涉及到失去带白色背景的细节，还是多保留一些来自背景残留色。数据重置到零。i'm not sure this helps us in anyway. this targets soft edge transitions along the edge of selection and makes them more abrupt, more visible, let me go between 0 and 100%. so you can see the difference. there're little place where it shows up. i'll skip this feature. use ctrl 0 to fit image to your screen. it's a good way to reveal even more of those revel hairs. by sliding it to right we're growing our selection. this reveals more of that white highlights, but again, that can be edited out. because i havne't worked on my selection so far. the results are spectacular. i'll paint a bit around hair. if i slide shift edge to the right, we can see all these fine hairs are coming back up. but they're accompanied by white, which is not ideal. you're eating into selection, it's similar to what we did in our selection exercises, where we decided it would be best to go in a few pixels rather than get any extra ones from background. then reset value to zero.
用Ctrl Alt Z退回去几个步骤重复修剪。从新工具栏选择“修剪边缘刷子”，开始在头发周边绘制，找回细节头发丝。我的建议多点击几次，而不是求一劳永逸。哪怕用Ctrl Z退回去修复几次。最好一次处理一块。预览模式调节到“在图层上”。可以看到人物在不同背景上。仍可以看到从先前背景残留的图，不是大问题。勾选底部的“净化色彩”，可以帮助我们解决问题。用“转化边缘”调节到20-50%可以做个很好的选择。use Ctrl Alt Z, we go back several steps, so we can get to work. i'll refine all around her contour to bring back some of those messy hair, my advice is you click several times rather than clicking and dragging in one swoop. this because we can use Ctrl Z to fix any problems, it's best to patch one area at a time, this is looking good. change view mode on layers, so we can see how this would look on a new background. but we're still seeing some white on her hair from previous background. not a problem. enable decontaminate colors from the bottom. and this will help us out tremendously. let me shift edge i can also play around with shift edge just a bit. i'll increase it to 20% or so. hit okay get selection.
85.02-8.10
Channel Selections
通道选择
用RGB图像是一个通道不同颜色，传递不同信息。点击任意一个，照片不同部位高亮部分。可以帮助我们创建复杂选择，很难单独萃取的选择。隔离灰色背景，如果绘制影响周边的，不是想要的结果，取而代之，比如我想隔离黑色线条，单独调节黑线条。移除背景色。通过热键Ctrl+I调取“水平指令”，可以获得窗口。右侧滑块移动左侧，你可以看到背景褪色消失了。左侧滑块移动右侧居中，黑色线条增粗了。但是不建议移动过了，黑色会出现不平滑杂色。take us to channels RGB image has one channel per color each of them contains different info about image. so as i click on any of these. you can see how each one highlight various parts of photo. this can help us create complicated selections that would have been otherwise very hard to pull off. if i try to paint over it and affecting everything that's not what i want, instead, i'd like to isolate black lines and work on them alone, remove background color by using level command through control I. you'll get this window, tab right handle and put it towards the left side, you can see background color fades away. for the left side, i want to crank up dark lines because my channel selection is going to be that much better if these are as black as possible. as i go back and forth, you can hopefully see the difference. you don't want it too far to right, because that will create some nasty jagged edges.
现在移动到通道滑块，绿色 红色 RGB画布没有变化，因为目前显示黑白色。选中的是白色，所有黑线条没有被选择，可以“反选”，操作方式“选择-反转”，当看到蚂蚁行军线条知道是选中了，按住ctrl选择任意通道，如果你保存下载文件只有被选中的白色的，黑色的被忽略了。用反转的指令。现在是选中的黑线条。为了体现选中黑线条调节的灵活性，加入实色调节图层，选择任意颜色，同时隐藏原始图层。关于调节图层的好处，可以双击颜色，背景色随着选择而变化。now let's move to the channels panel. context click any of these, since all three have about same info. since this image is almost black and white. everything that white is selected, so all these black lines are not party selection. that means we want the complete opposite, select invert, you can't see from marching ants that we've made a big change. when you contrl click a channel. you load up all white parts and all the black areas are ignored. with inverse command, we now have a fantastic selection of black lines. ensure good flexibility add a solid color adjustment layer. choose any color whatsoever, hit okay, you can hide that original layer. the great thing about this adjustment there is that you can change color on fly double click it.

选择图像不同的，我展示的新项目，图片都是不同的，不同图片不同的选择技能，无止境的完善。不要忽略套索工具，纵使你可能倾向于选择更有力的高级工具。selection should be fun each image is different, keep an open mind, when i'm presented with a new project, because each image is different, you never stop improving selection skills, don't neglect lasso tools, although you might be inclined to jump to more robust tools.
当你想展示视觉呈现的时候用快速选择工具。这是容易忽略的但是工作中可以帮到你。帮助选择编辑重点，选择不好的话，任何任务都举步维艰。the pen tool is one of strongest allies. use the quick mask tool whenever you need, a visual representation. it's also often neglected feature that can aid you in your work. help us pinpoints edits, without them, any task will become exponetically more difficult.
