Save & load selection

 保存&下载选择

• 如花了20分钟，丢失了选择的，太可惜，学会保存。搜线保存方法首先去主菜单，点击选择-下拉菜单-重新选择，丢失图片的危机解除了，一箭双雕，既保存了选项，同时保存了选项。 如果关闭PS，还是会丢失，不会永久保存。如果看标题标签末尾.JPEG拓展名，不能保存这类信息。选择保存信息，接下来关闭PSD，选择下载选择，下拉菜单选择PSD。if i spend 20minutes on selection, now i made selection back, obviously Ctrl2 isn't going to be much help, because i lose stuff. go to top menu, click on select, from the dropdown, choose reselect, with crisis averted. now i got best of both worlds, i get to keep progress as well as my intricacy sections.if you clos PS, you'll no longer have it available, won't work indefinitely. save it as PSD file, go to file, now go to select save selection. next i'll close PSD. select load selection from drop down choose PSD.

Activity Change Color T Shirt 2

改变T恤颜色

1. 这两种方案并非专业喜欢的，因为没有给你灵活性，技术会毁损性的，确保大小默认合适的。我想直接给T恤涂色，用快速选择工具隔离，增大刷子大小，退出远观看起来好。 those two methods aren't the one professional prefer, because they don't give you enough flexibility, this technique is going to be non destructive, make sure they have a decent sized photo. i only want to target shirt, so we need to isolate it. grab my quick selection tool and i'll increase my brush size to about it, when you zoomed out everything looks better. 
   

2. 当我们近观时，看到手表的问题，衣领的问题，手指拦住工具选择衣服的问题，缩小刷子大小，搞定左半部分，右部分相对需要仔细一点，因为区域有点暗，导致误选偏暗的牛仔裤。按住Alt开减去选择区的不需要的像素类型。as we move closer, you can see there're problems with watch, a few issues with colar, his fingers prevented my tool from going all way in, i'll shrink brush considerably and i'll start adding in these areas. on the right side will have to be extra careful. because this area is considerably darker, so it will be tempted to select jeans as well. hold down Alt and start painiting away. the more you go over an area with Alt, the better PS will do, i don't need those types of pixels in my selection. 

3. 衣领并没有被照顾到，用调节图层，用色相和饱和度，注意到蒙版，因为有活跃选框，图层蒙版理解这是作用于选区。所以创建包含T恤到蒙版。打开上色的复选框，现在简单色相数据足够，有些颜色看起来很明亮，建议避免太大饱和度导致失真。建议色相360，饱和度50，亮度-20刚刚好。i'll leave collar alone as well as any potential areas that didn't receive enough attention. next we'll using adjustment layer. go and enable hue and saturation. notice the mask, because we had an active selection. layer mask understood work on that area specifically. so it created a mask that contains only the shirt. enable colorize option. now simply move hue value. some colors might look a bit too bright. my advice is you turn down saturation for a realistic look. the hue value is 360. saturation is 50. for lightness use negative value of minus 20.

4. 点击蒙版缩略图开始绘制，用该情况的白色，随时调节刷子大小和硬度。当替换颜色，创建好选择。调节图层是灵活，可以修改的，前提是图片大小合适的。总之学会了选择，现在用快速选择工具调节。click on mask thumbnail and start painting. use white in this case. it goes without saying you should adjust brush size and hardness. go to method. when i want to replace colors, create a good selection. then use an adjustment layer. it's flexible. non destructive. as long as you have a decent sized images. you've leanred about selections.

Introduction 

简介

• 我们继续探索选择工具，套索工具，钢笔工具。比如从照片移除各种元素，比如把人从背景中圈选出来，可以从选择工具获取设置。我们继续学习新技能，给下阶段做准备。we'll continue to explore selections, we'll talk about lasso tool, pen tool for selection. we'll remove various things from photos, we'll also clip out a person from BG, you'll also pick up some tips about selections and how you can improve them with a few trick s and settings.

Use Lasso Tools 

套索工具

1. 热键L调取套索工具，当你想做粗略选择，三种方法，套索工具是某种钢笔工具，在画布绘制做出选择，抗曲折保平滑复选框选中。你可以羽化创建柔化边界。可以用和字幕框选工具同样的调节工具，shift加入选择，光标后加号。Alt移除选择，shift+Alt给交界选择。 let's start section with lasso tools, when you want to make a rough selection, you have three of them in total, hotkey is L. the regular lasso tool works sort of pen tool. you grab it then you can draw anywhere on canvas to make selection. the anti-aliasing should be turned on. you also have feather option that create soft edges. you can use the same modifier keys that you used for marquee tool,shift adds to selection, notice plus symbol next to cursor. Alt removed parts of it. shift +Alt combined will give you intersection.  

2. 工具相互搭配使用。比如字幕框选矩形，可以添加套索工具移除部分，可以用魔术棒，进一步移除套索工具的部分。套索可以从画布选择，用来调整另一个选择，当你想包含或移除部分区域的时候。当你涉猎多边形套索工具，抗曲折平滑和羽化，依赖点击可以更精确。在任何一点，松开鼠标，只能是直线，如果你客体有曲线，这不是理想工具。all those tools interwined with each other. you create a rectangular section with marquee tool, then you jump in with a lasso tool remove parts of it. you use magic wand further improve your selection by removing a big chunk with lasso tools. lasso tool is used to quickly pick up something from canvas. you'll use it to adjust another selection, mostly when you want to include or remove farily large parts. when you're going over to polygonal lasso tool. this has the exact some features as normal lasso. so anti-aliasing and feather, but it has better precision because it relies on clicks. at any point i can click and change direction. there's no give. we only have straight lines. if your object has any curves. this is not ideal tool for job. 
   

3. 多边形套索工具和多边形工具不同的，多边形创建形状，多边形套索创建选区。磁性套索工具，顶部有很多特性，有控制工具特性。点击，不再点击鼠标，在上面停留一段时间，点击最开始的点，现在移动鼠标。PS自动添加锚定点，基于我设置的点，设置数据越大，锚定点越大。magnetic lasso tool, immediately we get more features at the top and those controls tools' behavior. i'll click and i'll stop hovering over edge of building. i'm not clicking at all. i clicked once for initial point. now i'm moving mouse. PS is automatically adding anchor points based on frequency i set up top. the higher i raise it, the more anchor points i'm going to get. if the shape is complicated, more anchor points will result in a better selection. 

4. 如果搞砸了，可以重新开始，按空格键，删除最后锚定点，可以继续纠正线走向，最后接到最开始点，闭合选区。光标改变形状。可以增加对比度。相关的宽度，就是PS选择边缘，大概预留10像素，磁性套索工具，快速选择非常好的工具。if i somehow messed things up and i don't want to start over, i can press back space key. this will delete your last anchor point, you can continue on correct line with all selections, you need to go background to the original point and close it off. you'll see cursor will change its appearance. you may need to ramp up contrast. the area where PS looks for edge, it's usually a good idea to leave it at around 10 pixels, that's magnetic lasso tool, a pretty solid option for making fast selecting with fairly high accuracy.

Pen Tool Overview 

钢笔工具概述

1. 探讨选择目标的钢笔工具，是胜任各种项目的强大工具。通过热键P抓取钢笔工具。最重要的设定是左上的，下拉菜单，可以设置路径。选择后创建锚定点，黑色实点，再点击，相连起来。如果点击拖拽，得到曲线，可以调节圆角。可以再点击，相反方向，不放松鼠标，可以得到曲线，因为钢笔工具可以延续线条走向。we'll talk about the pen tool for selection purposes. it's a powerful and versatile option for any project. grab pen tool through its hotkey P. the most important setting is this one, in top left, use this drop down, you want to set it to path. you click once to create an anchor point, its this black dot here, you click again, now there're connected. if you click and drag, you'll get a curve which is much more useful in your day to day work. you'll adjust its roundness. if you click it again, but in an opposite direction, and without holding down your mouse, you'll get curve, pen tool, wants to continue particular flow.

2. 如果你不用热键，可以点击钢笔工具徽标，菜单的最后，反转工具，点击握住鼠标，任何锚定点会被改变。在选择目标的钢笔工具+路径模式。如果想管理路径，有特殊的面板是右侧固定面板展示的，如果你没有，从主菜单窗口-路径来调取，像缩略图的改变，这是呈现形式。选择路径按回车，找到最后打开的版本。避免丢失工作，双击路径打开这区域，输入你可以辨识名字，保存在PSD内。you can click and hold on pen tools' icon, for the last one, from fly out menu, it's convert point tool, i'm clicking and holding mouse click. any anchor point and click on will change, we're using pen tool in path mode, this is useful for selection purposes. if you want to manage your paths, you have a special panel for it. i have it docked here, but if you don't see it, go to window paths. you can see thumbnail changes, this is a representation of what's going on. if you hit enter, then you click on work path, you're going to get the latest one. to preventing losing your work. you can save path by double clicking in this region, input any name, it's going to be saved inside PSD. 

3. 回到最初锚定点，这是第一个，光标停留在上面，光标旁边的圈，意味着闭合路径，创建选择，创建路径两个主要的选择形式，点击路径面板底部第三个徽标，我偏好的方式右键选择。弹出对话框问是否选择羽化，不需要。保留光滑选项选中。在选项栏，保留自动羽化。you go back to the initial anchor point, this was my first one, if i hover over it. i'm getting a circle next to cursor. that means i'm about to close this path now we can create selection. there's two main choices to create a selection from a path. you want to click on 3rd icon at bottom of path panel. preferred method is to right click, from this list of press make selection, ask me if i want feather radius, that's not the case. i'll always keep anti-aliasing checked because this prevents jagged edges, in the option bar, by default, we have this feature called auto. 

4.  当你在选中的路径停留时，可以加入想要的锚定点，光标旁边会有加号。可以加入新的锚定点，如果在存在的锚定点停留，可以加入减号标志，移除锚定点，路径保持关闭，不能移除一段，只是移除点。返回最初点关闭路径，右键选择创建选择。when you hover over a selected path. you can add as many anchor points as you want on it,my cursor changes, it gets a plus symbol, that means i'm about to add a new anchor point. click and drag. if you're hovor over an existing point, you'll get this minus symbol, which means you can remove it. your path will remain closed, as this doesn't remove that segment instead of remove point. once you've closed off path by going back to origin point right click and choose create selection.
