Activity Soften Skin Imperfections
柔肤遮瑕
提高相片的饱和度和对比度，用调节图层做。improve photo saturation and contrast, do that with adjustment. improve photo saturation and contrast.
另外打开调节对话面板的方式，主菜单“图像”，下拉菜单“应用图像”，弹出对话窗口。go to top menu and click on "image", from the dropdown, choose "apply image", we have new window with options.
该“应用图层”对话框注意四点，第一，“来源”选择“柔肤遮瑕”；第二，“混合模式”选择“多重”；第三，“不透明度”调到“50%”；第四，“预览”勾选上。we'll interested in four things. 1st, the source drop down to soften skin imperfections. 2nd, "blend" choose "mutiply". 3rd, opacity bring down to 50%. 4th, enable the "preview".
首先，图层面板，选中图层右键转化成智能模版，保护像素。其次，如何调出柔肤调节预览面板？从过滤主菜单，选择模糊-表面模糊，弹出对话版，最后柔肤对话版注意两点：A, 模糊直径的选择，取样多少; B, 阈值的选择，若是柔光模式太强，容易让照片看起来像是瓷娃娃，C，避免影响衣服头发材质，选择黑色前景绘制，硬度的调节，涉及到帽子头发灯不同部位过度平稳。1st, talk about smart objects hide details, how they protect pixels. right click layer and choose convert to smart object. 2nd, go to filter-blur-surface blur, we get to sliders, A, Radius of blur, sample for blur; B, we'll determine how strong effect is going to be, if you set it too high, you'll end up with plastic looking. C, to avoid be trouble is it's also affecting texture of clothing as hair, grab brush tool paint with black, hardness should be turn down to 50%.
接下来针对1.衣服细节的找回；2.头发凌乱还是选择柔滑掉，依据要求选择；3.皮肤可以去掉表面柔化恢复自然；4.调节刷子不透明度可以多一层掌控。1.bring blouse detail back in. if you paint over the area that shouldn't be softend, take your time, adjust brush size if needed. 2.hair is of foucus, paint over fade int backgournd, or leave them in remove. 3.one way about neck region, turn down surface blur effect on the heavy side. 4.second option about opacity give more control. when you do have brush tool active change opacity to like 30%, bring it back detail in skin.

Use Eye Dropper & Swatches
用吸管&样本色版
工具栏前景背景的区分，默认颜色黑白色，上面矩形是前景，下面矩形是背景。the top square from tool box controls foreground. the one at bottom acts like your secondary one.
取色器作用？比如你想改变前景背景的颜色，点击，打开取色器面板，左下角取自于网络，十六进制代码的，取色粘贴。通过预览框判断颜色修改的变化。if you want to change top and bottom square color. the most popular way of sharing. colors on web is through hex code. you can get nice one from web and paste them here. i can tell the change through preview in new box.
如何交换颜色位置？第一，选择取色器；第二，热键X交换前后背景颜色位置；第三，右上小徽标切换交换颜色前状态；第四，左上角徽标转化成默认黑白色或按D，新设定取色自动消失。how to swap color position? 1st, click get the color picker. 2nd use hotkey X to swap position. 3rd go over tiny icon with two arrows to swap the FG BG color position. 4th, press hotkey D or, press the other small icon revert to default color. the previously selected gone away.
取画布颜色，前景颜色随之变化。如何取色第2色？翻转前景后景位置，这样获取新颜色。identifuy it through color from the toolbox, click anywhere on canvas, your forground color will change. how to choose the secondary color? use X to flip them around, click and set another color.
如何分辨当前颜色，样本颜色，松开鼠标就选定颜色。when you hold down mouse, see its divided in two parts top half show what your currently sampling, the bottom part is there to show what current color is. so you can compare sampling and current color. then let go end up with left side.
如何选择像素的颜色？选项栏“样本”选择最大水平，放大的网格中，可以看到样本取的点像素，或几个网格的均色。how to pick up individual pixels. PS work with raster Images, that are made out of pixels. zoom into maximum level. you can see grid shows up, click inside any square, you've got pixel color, this is called point sample mode. or you can find color code that's on average for that spot.
给样本应用于“当前图层”还是“所有图层”，这对于几个图层的大项目非常友好。sample "current layers" or the "all the layers". if you're working on larger project with several layers, the easiest option to change settings, get exactly what you click on.
吸管适合从网站或另一个屏幕吸取色彩，同时打开取色器对话框，为了从预览框可以看到吸管吸取不同颜色，预览颜色随之变化。可以从网站和/或PS界面借颜色。use eyedropper tool, outside of photoshop, if you have two monitors, you can resize window side by side, with grab browser, with eye dropper activated, i have color picker open, you can see changes more clearly. you can borrow great color from favorite websites, or sample from PS interface.
可能你的问题是，如果吸管和取色器同时开启，去外网借颜色的吸管会受到取色器的干扰吗？答案是不用担心，因为取色器开着，到外网借颜色时候，自动变成吸管光标。it doesn't matter if use eye dropper directly. if you double click on any of these boxes, and use color picker, when i'm outside window, it turn into eye dropper symbol.
如何处理两种以上选取的颜色？就涉及到颜色样板的概念，从主菜单窗口-颜色样板，弹出加入样板的对话框，到面板光标变成油漆桶。或者点击左侧工具栏前景背景，选择加入样板的按钮。what if i want to work with more than 2 colors. you can go to top menu window - swatches. sample color, move over to panel, corsor changes to paint bucket icon. select any number of colors, have them saved in the panel. i'll add the swatch with whatever i want the alternative is to click on BG or FG colors, hit add to swatches.
如果样板颜色太多了，如何删除呢？按住Alt，光标变成剪刀，点颜色就可以删除。how to delete color click. hold down Alt, cursor will change into scissor icons, click icon, we'll have available option to do that.

Optional Fix Eye Dropper
可选修复吸管
为了演示吸管工具使用，画布上三个色块，对应图层面板的顺序。eyedropper tool in case you're seeing perform in strange way, we have three squares on canvas, top to bottom in order in layers panel is consistent.
问题是为什么，针对改变中间色块，取色器吸取底部色块，中间变得同底部色块，但是取色器选取顶部色块，中间色块融入到白色背景里，为什么呢？因为你设置样本是当前色块之下，PS忽略掉顶层方块吸取的颜色了，认为是背景白色。adjust square color, double click square thumbnail, move around in color picker, adjust color, you'll instantly get to see change. but if you pick up the red top square, the middle one is not red, it's disappear. because that's what you sampled, even though you tried on red square, PS disregarded it. what's underneath is BG layer, which is white. all in all due to setting from eyedropper tool.
看看导致PS忽略当前色块前面取色无法应用的设置是什么呢？怎么修改颜色设置，才可以把活动色块上面取色的应用上呢？答案是把选项栏样本下拉菜单的“当前及以下”切换成“全部图层”。hit sample dropdown, swap "current & below" any layer that's above your shape won't get noticed by PS.
如何应用“渐变重叠”？点击右下角FX徽标-渐变重叠，顶部颜色就是遮罩颜色预览，但是需要按确认键，调节遮罩颜色才会生效。click FX icon, enable it, set the color bar, then the top part in the preview position is color of shade, that's why PS disregarded part of the gradient samples. do hit the okay, then you select graiden set in place, eyedropper would work as expected when related be gradient or color overlay style.

Resolution VS Image Size
分辨率VS图像大小
像素越大，更细腻的诠释图片，图片质量越好越清晰，如何查看像素大小呢？方案一，从属性面板看一项主要的像素大小，方案二，热键Ctrl+Alt+I，整个图像像素信息都可以找到。higher size means a better looking composition. we can see a width of pixels and a height of pixels.1st, from the properties panel. 2nd, you'll get a total pixels value for entire image, that's how many pixels you'll find in image.
如果你看到“像素✖️像素”的格式，指代的是“图像大小”。针对选项栏像素大小，选项栏如果用"百分比"来显示，下拉菜单可以选择"像素"。 initially, it'll show us present value. right click, change it to pixels, anytime you see something like pixels by pixels, that's refer to image size.
“分辨率”单位是“像素/英尺”，针对打印建议300像素/英尺，针对网页项目浏览建议72像素/英尺。“图像大小”建议“500✖️100=50K像素”。to sum up, image size refers to number of pixels 500 by 100 pixles. Resolution is only relevant for printing purpose, idea value is 300 pixels per inch, for digitally increase resolution, from 72 to 300.
为什么是上面推荐的参考范围，因为更高的分辨率打印出来仅仅是模糊的，放在网上不会更好的效果，只会降低PS运行效率。 there's a key key distinction here, no matter how much you increase pixel density, photoshop won't look any better on screen. if you use a higher resolution for project. not go to print it's completely useless. it's going to hurt performace. if we try to digitally increase resolution.

Optional Change T-Shirt Color
替换T恤颜色的最佳方案
针对替换T恤颜色的任务，左侧工具栏按住“刷子工具”弹跳出下拉菜单“刷子工具+铅笔工具+混合刷子+颜色替换”，其中选择“颜色替换工具”，弹出取色器对话框，选择想替换的颜色。上面工具条“模式”有“色相+饱和度+照明+颜色”，其中推荐选择“颜色”。go over to the left side the toolbox, click and hold on the brush tool, from the menu, we choose "color replacement tool". we can play around with color picker, the advice is stick to color mode.
为什么选择颜色模式呢？因为“照明模式”匹配前景颜色，看起来像是水洗的；“饱和度”不影响原始颜色和强度；“色相”模式看起来像是鲜活颜色上的污垢，因为不影响色相和明亮度；because the "luminosity isn't look right". "saturation mode" isn't great when you want to adjust intensity of initial color, it's going to wash out. "hue mode" make it looks blotchy on vividly colored areas because it doesn't affect the saturation or brightness.
刷子大到500像素或中度，用左右方括号快捷键放大缩小刷子大小。因为有的需要大面积涂抹，有的细节需要小刷子修补，因为袖口等皱褶衣服颜色非大片实体颜色。因为PS有地方涂抹不够到位，容错率20%，解决的方案耐心的图模拟次。硬度50%刚刚好。Brush large or middle, should be fairly large, say 500 pixels. somewhere in middle,as you go along, we can adjust size as we go, that's because if you focus on color and brush is too big,decrease brush size and zoom in better address spots, otherwise you'll have a hard time with sleeves. the color isn't as solid as in region, that's why we having trouble replacing it. “Tolerance” impact how loosely photoshop will replace colors, start with 20%."Hardness" 50% should be fine.
如何处理袖口皮肤交界处，如何避免衣服颜色涂抹到皮肤上，如果涂抹到皮肤上如何补救？答案是第一选择临界衣服颜色和皮肤颜色，第二匮乏灵活性，需要耐心图模拟次。补救方案是用ctrl+2重做，鼠标建议停留20-30秒，尽可能避免重做，一旦重做，所有的步骤付诸东流。如果硬说这是PS缺陷的话，那么补救方案也浅显易懂。tricky to avoid painting over skin? that's trade off, on one hand, this is simple to set up, choose a color and start painting. on the other hand, it's not very flexible. when go over skin by accident. your only choice is use Ctrl+2 to undo.once you undo, you lose all your progress. troulbe is if you're holding down mouse click for 20 or 30 seconds at a time.it definitely has it's drawbacks, but it's easy to remember.
如何灵活的调节？主菜单-图像-调节-颜色替换。第一个按钮展示编辑之前的颜色，第二个按钮是替换编辑的颜色，模糊滑块调节到200，可以看到中间颜色融入背景。第三个按钮，保存颜色簇，不同替换版本的颜色分别保存。move over to the top menu the image, adjustment, choose the replace coor. from the 1st icon, you can see the previously selected as color choice. switch to the 2nd or the middle icon, immediately show up preview you can edit it. this will add to our affected area. if you adjust the fuzziness, bring it all the way up to 200, as i turn it down, we can see how other areas fade away. switch to 3rd icon, address the trouble isolating parts of image. you can enable or diaable localized color clusters and saw how somthing's affected your photol.
最后谈一谈“颜色替换”对话面板，最下面“饱和度 像素 亮度”滑块进行调节替换颜色。可以用Ctrl+1放大看替换效果。we can work with three handles, hue is what you're interested in, make sure your zoom in just a bit with hotkey Ctrl+1. now move these slides up and down and swe how new looks.

Optimize Project Size
调节项目大小
减少存储空间的方案，帮你节省拓展存储空间的没必要经济花销。learn how to reduce PSD file size except archive approach unrelative PS, aiming to avoid give any file size economy.
除了压缩文件，减少文件大小，请问PS相关还有什么减少文件大小的操作呢？广为流传的隐藏文件的建议究竟实不实用呢？本章节一探究竟。how you can shrink your PSD file? there's lots of tips roaming around web on this subject, it's best to hide all layers before saving it. let's try it out. we can compare size as i try out different things.
第一种情况，如果从网络下载的大文件，你和同事都没有进一步处理大文件，也不需要大文件的情况下，光栅化，如此缩减到50%大小，encounter scenario lots of times. this frequently happens when you download large images form photo websites. if you're sure you won't need them at a larger size them rasterize them. if you were planing on resusing some of large graphics, your options are limited due to their 50% size.
当然大文件是不可恢复的，没有光栅化的漏网之鱼删掉就可以了，如此到25%大小。we still have quite a few other that are hidden, i see no colors associated with them. now the project is about 25% of what it used to be.
为何相对于光栅文件而言，智能化文件占容量呢？所以尽可能不用智能图层就少用，或者同样功能图层替代。why smart objects come with cost? this does translate just in hard drive space, they also require a bit more juice from computer overall. in essence, smart objects are the only substantial resource that clogs up PSDs, regarding other tricks or techniques. that's how to optimize projects, remove excess smart objects.
接下来针对光栅化不同类型的文件，右侧图层面板筛选工具选择，比如智能图层 资源图层 形状图层，节省空间。raster smart merge layer togethe, shape layer, source layer, use filter system from the up top, you'll see some are scaled to about 5% of size.

Non-Destructive Editing
无损害可修复的编辑
什么叫做无损害的编辑？意义是什么？意思是永久性的像素改变，不用考虑重做了，某点重做也毫无意义。为什么编辑会没有修改的机会的，举例子说明，比如用颜色置换工具时，永久性改变图像像素，没有可见滑块可以去修改调节。类似的用调节图层，或类似橡皮擦在图片上绘制，没什么值得进一步调节的，ctrl+Z撤回。what's destructive editing? this doesn't take into account the possibility of undoing because that's useless at a certain point. that's because every time i'm painting with color replacement tool. i'm permanently changing pixel aspect of image. there's no slider, no visibility icon that you can toggle. the same thing applies to adjustment, or taking an eraser and going over image like if you have control+Z, you can't get to that state and further adjust settings.
问题是举例子如果你添加了胡须，想重新编辑颜色，一撤回，为了颜色得不偿失的丢失了所有重建的步骤。这就引出了可重建性技术步骤。首先智能图层，主菜单筛选-模糊-高斯模糊，避免重复犯错，这次转化图层为智能图层，关闭后可无限次调节。the thing is, if you want to edit color, you could potentially undo a thousand times that's limit, i'd lost any mustache. so that's how important using non destructive techniques they are. we've already spoken a bit about smart objects. i'll go to filter-blur-gaussian blur, now i can't do anything, this time, i'll final applied as a smart filter, which i have complete control over it.
右下角选择曲线调节，可以调节图层可见度等。这就是可见的调节。you can always go back and fine tune their settings. you can turn off their visibility, that's another great way of working on project without permanent consequences.
