Use Lasso Tools?

用套索工具

1. 有些選擇比較困難，熱鍵L調(diào)取三個(gè)選擇工具。常規(guī)套索工具也是鋼筆工具一種，在屏幕繪制選擇，核對(duì)勾選保持平滑。羽化效果柔化邊緣，用同樣的變形關(guān)鍵，可以用于框選工具，Shift選區(qū)相加，光標(biāo)旁邊加號(hào)。Alt移除部分選區(qū)，光標(biāo)旁減號(hào)。Shift+Alt組合選區(qū)交集。工具都是相互關(guān)聯(lián)的。用框選工具創(chuàng)建的矩形選區(qū)，然后用套索工具移除部分選區(qū)，魔術(shù)棒移除部分套索選區(qū)進(jìn)一步完善。套索工具用于從畫布快速的選區(qū)，可以用于調(diào)整其它選區(qū)，當(dāng)你想加入或移除大部分選區(qū)的時(shí)候用。當(dāng)?shù)蕉噙呅翁姿鞴ぞ哌x區(qū)時(shí)，和正常套索工具特征相似，抗曲折和羽化功能都存在，依賴點(diǎn)擊選區(qū)相對(duì)精準(zhǔn)些。可以在任意點(diǎn)點(diǎn)擊，如果你選區(qū)有弧度曲線，這種點(diǎn)擊選區(qū)方案并不理想。the hotkey is L you have three of them in total, the regular lasso tool works sort of pencil, you can grab bit then you can draw anywhere on canvas to make selection. the anti aliasing should be turned on. you also have feather ption that creates soft edges. you can use the same modifier keys that you used for marquee tool, shift adds to selection, plus symbol next to cursor. Alt removes parts of selection. Shift+Alt combined will give you intersection. 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 wands, further improve your selection by removing a big chunk with lasso tool. polygonal tool has better precision because it relies on clicks. we only have straight lines, if your object has any curves, this is not ideal tool for job.?

2. 針對(duì)多邊形套索和多邊形工具容易混淆點(diǎn)，多邊形套索是選區(qū)工具，多邊形工具是形狀工具。磁性套索工具，頂部任務(wù)條特征類似，都是控制工具行為的，點(diǎn)擊，鼠標(biāo)懸空停在邊緣，并沒(méi)有繼續(xù)點(diǎn)擊，創(chuàng)建原始錨定點(diǎn)，現(xiàn)在移動(dòng)鼠標(biāo)，PS自動(dòng)加入其它錨定點(diǎn)，基于頂部我設(shè)定的頻率數(shù)據(jù)來(lái)添加。頻率越高添加錨定點(diǎn)越多，如果形狀復(fù)雜，錨定點(diǎn)越多，選區(qū)效果越好。don't confuse polygonal lasso with polygon tool. there're two completely different things. polygon create shapes, polygonal lasso creates selection. magnetic lasso tool immediately we get more featurers at the top and those controls tools behavior. i clicke 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, move anchor points will result in a better selection.?

3. 如果選區(qū)選擇搞壞了，不愿意重來(lái)如何處理，按刪除鍵，刪除掉最后錨定點(diǎn)，繼續(xù)糾正線，需要回到原始點(diǎn)，關(guān)閉選區(qū)。觀察光標(biāo)點(diǎn)變化。如果圖像被洗刷掉了，可以繼續(xù)增加對(duì)照度。選區(qū)最小寬度，在選項(xiàng)欄設(shè)置10像素。這就是磁性套索工具。if i somehow messed things up and i don't want to start over, i can press backspace key, this will delete your last anchor point, you can continue on correct line, back around to original point and close it off. you'll see cursor will change its appearance. you may need to ramp up contrast. the width the area where PS tooks for edge, it's usually a good idea to leave it at around 10 pixels, that's magnetic lasso tool.

Pen Tool Overview?

鋼筆工具概述

1. 探討選區(qū)目標(biāo)的鋼筆工具的強(qiáng)大多功能作用。熱鍵P調(diào)取鋼筆工具，左上角下拉菜單選擇路徑。點(diǎn)擊創(chuàng)建錨定點(diǎn)，這是黑點(diǎn)，再次點(diǎn)擊，就相連了。如果點(diǎn)擊拖拽，調(diào)節(jié)曲線和圓角，這是常用的參數(shù)。再次反方向點(diǎn)擊，鋼筆工具產(chǎn)生的弧度體現(xiàn)延續(xù)性，并沒(méi)有嘎然轉(zhuǎn)向。如果不用熱鍵，可以點(diǎn)擊鋼筆工具徽標(biāo)，彈出的菜單最后一個(gè)轉(zhuǎn)換點(diǎn)選項(xiàng)，功能是任意錨定點(diǎn)都可以點(diǎn)擊轉(zhuǎn)化。比如我們用鋼筆工具路徑模式，對(duì)選擇為目標(biāo)這模式管用的。如果想管理路徑，我右側(cè)固定該特殊面板，調(diào)取方法是，從主菜單窗口-路徑，可以看到右側(cè)面板縮略圖的變化。we'll talk about the pen tool for selection purposes, it's a powerful and versatile option for project. grab pen tool through hotkey P. the setting is this one in top left, use the dropdown, you want to set to path. you click once to create an anchor point, it's this black dot here, you click again, 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. you can click and hold on pentool's icon, the last one from fly out menu, it's convert point tool. 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. go to window paths, you can see thumbnail changes.?

2. 如果點(diǎn)擊回車等于選擇工作路徑，得到最后一個(gè)路徑，避免工作過(guò)程丟失，可以雙擊該區(qū)域，輸入名字，保存在PSD內(nèi)。回到原始的錨定點(diǎn)，停留在錨定點(diǎn)上，光標(biāo)旁圓圈，關(guān)閉路徑后，現(xiàn)在開(kāi)始創(chuàng)建選區(qū)。創(chuàng)建選區(qū)的方案主要兩個(gè)，一個(gè)右下面板選擇徽標(biāo)，點(diǎn)擊第三個(gè)路徑徽標(biāo)即可創(chuàng)建，另一個(gè)我偏愛(ài)方案右鍵菜單選擇。彈出對(duì)話框羽化半徑，涉及不到這問(wèn)題，主要確定勾選了保持平滑。在選項(xiàng)欄，默認(rèn)勾選保持平滑。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. 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're two main choices to create selection from path, to click on 3rd icon at bottom of path panel. my preferred method is to right click from the list of press make selection. if ask the feather radius, that's not the calse, i'll always keeps anti-aliasing checked because this prevents jagged edges.?

3. 在出現(xiàn)的路徑，光標(biāo)移動(dòng)道被選擇的路徑，不需要點(diǎn)擊，出現(xiàn)很多錨定點(diǎn)，看光標(biāo)旁出現(xiàn)變化，出現(xiàn)加號(hào)，代表增加錨定點(diǎn)。如果鼠標(biāo)停留在已經(jīng)存在的錨定點(diǎn)上方，光標(biāo)旁出現(xiàn)加號(hào)代表可以移除，路徑仍舊是閉合狀態(tài)，不會(huì)移除某段路徑，只會(huì)移除路徑上某些錨定點(diǎn)?；氐皆c(diǎn)關(guān)閉路徑。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, if you hover 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 the segment instead of remove point. once you've closed off path by going back to origin point.

Use Direct Path Selection Tools?

用直接路徑選擇工具

1. 當(dāng)處理鋼筆工具時(shí)，設(shè)計(jì)直接選擇工具和路徑選擇工具。路徑選擇工具黑箭頭，目標(biāo)是展示路徑的。P調(diào)取鋼筆工具，光標(biāo)旁星號(hào)，創(chuàng)建新路徑。如果創(chuàng)建好的路徑需要進(jìn)一步編輯，就涉及到路徑選擇工具。選擇局部路徑就可以，因?yàn)樵摴ぞ卟⒉会槍?duì)路徑上的錨定點(diǎn)。不管如何框選獲得整個(gè)路徑，當(dāng)去選擇時(shí)，盡量用黑箭頭，點(diǎn)擊圖層面板，展示輪廓，或者從畫布上獲取。when you're dealing with pen tool. direct selection tool, path selection tool. the path selection toll is the black arrow, its only purpose is to show your path. if we grab pen tool, you'll notice asterisk symbol next to cursor, this means we're about to create a new path. i want to further edit the existing tool comes into play. just cover a tiny bit is enough, that's because this tool doesn't target individual anchor points. 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 layer panel and reveal its outline. you can grab it from canvas.?

2. 切換到鋼筆工具，加入或者移除錨定點(diǎn)，調(diào)節(jié)曲率的切線直線。被選中可調(diào)節(jié)的點(diǎn)實(shí)心黑色，沒(méi)被選中點(diǎn)白色。所以白箭頭選中錨定點(diǎn)用的?？梢岳L制白色背景框內(nèi)，這段區(qū)域內(nèi)錨定點(diǎn)被選中了。白箭頭選錨定點(diǎn)工具和黑箭頭選路徑輪廓工具用Shift+A來(lái)切換。按回車去選擇，或直接點(diǎn)擊面板的路徑。i can switch back to 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 them you can adjust 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 direct selection tool helps you select individual anchor points from a path, hotkey A you can cycle between them. i'll deselect it with enter key or click on path from panel. you see it 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.?

3. 選中后出現(xiàn)手柄，上調(diào)曲率反方向的延伸。這就是項(xiàng)目中，如果路徑不夠理想，按Ctrl開(kāi)始調(diào)節(jié)曲率切線的手柄，觀察曲率平滑度，錨定點(diǎn)數(shù)量越少，路徑越平滑。最后鋼筆工具從草圖介紹的，如果你目標(biāo)點(diǎn)下一點(diǎn)，嘗試下直接拖過(guò)去，路徑并不理想，所以順著曲率的趨勢(shì)移動(dòng)過(guò)去。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 shift 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. 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.?

Activity Pen Tool Selections?

鋼筆工具的選擇

1. 挑選三個(gè)進(jìn)行分析，剩下的接力完成訓(xùn)練。目前需要直線，按住Shift創(chuàng)建完美直線，縱然在形狀內(nèi)部，點(diǎn)擊中點(diǎn)，對(duì)稱的另一側(cè)也重復(fù)該步驟?？拷鼉?nèi)部也好過(guò)把背景裁剪到邊里。we have lots of shapes in this PSD, i'll do a couple, and i'll pass the torch to you. if i'll hold Shift, this will create a perfect line, even though i'll click somewhere indise shape, as you can see, no problems with it, click on middle point, now repeat process on the other side. i'd rather you have it placed inwards, this means wee lose one or two pixels from shape. this is much better than havign a white stroke all around it from background.?

2. 第二個(gè)是黃色和橙色倒L圖案，從左側(cè)頂部單獨(dú)點(diǎn)擊，第一個(gè)難點(diǎn)是，直線變成橢圓頭，這時(shí)候順著橢圓弧度進(jìn)行選擇，而不是直接跨過(guò)去，原因是順著橢圓弧度可以多個(gè)錨定中間點(diǎn)切線調(diào)節(jié)。第二個(gè)難點(diǎn)是黃色橙色中間交叉，都是直線條，這時(shí)候采用Alt減去中間點(diǎn)部位。we can start from the top left with a single click, now move down and click somewhere around region, before object starts to change its shape, we aim for another anchor point near this ara, because around here we can find its middle point, if we drag directly on the other side that would require a lot of fiddling. so drag towards right, we have pretty far out to match curvature. use Ctrl drag right handle inwards. on the next line it should be perfect straight, we click without any modifier key which require a bit of fine tuning, instead i use Alt and i'll click on anchor point, i'll get a perfect line. i don't afraid of changing anchor point placement, i'll circle back and look for symbol so i can close off my path.?

3. 第三個(gè)圖案是類似甜甜圈，從顏色交叉點(diǎn)部分開(kāi)始圈選，椰樹(shù)逐步點(diǎn)調(diào)節(jié)曲率，考核重點(diǎn)是第一，重心偏內(nèi)的把控。第二，針對(duì)不小心多選的錨定點(diǎn)的處理，按Ctrl鍵來(lái)去掉不想要的錨定點(diǎn)，第二個(gè)難點(diǎn)是需要近觀調(diào)節(jié)，迷失了，可以再遠(yuǎn)觀退出，近觀遠(yuǎn)觀的調(diào)節(jié)看準(zhǔn)。start from other 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. i'm going to require concentration, we can handle it. 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, just to be sure everything is fine, is to control click each anchor point and adjust handles.?

Quick Mask Mode?

快速蒙版模式

1. 本節(jié)需要處理的大面積的屋子和頂部小面積天空，屋頂和天空都是藍(lán)色，很容易選不中藍(lán)色的屋頂，誤多選藍(lán)色的天空，針對(duì)該問(wèn)題如何處理。如果是我我首選快速蒙版模式，但是大部分人的選擇是快速選擇工具，我們先看看快速選擇工具有什么不好。quick mask is a particular helpful way to check quality of selection and further modifying them. we have building, it's top edge is blue, our sky is blue as well, so that might thrown 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 lassor or better yet pen tool. i'll go with a suppar choice for job quick selection tool.

2. 用刷子涂抹房子，越是接近頂部藍(lán)屋頂藍(lán)天空的時(shí)候，越是避免錯(cuò)誤選擇，用Q熱鍵快速蒙版模式，如果圖層用紅色高亮，還是容易不選擇藍(lán)色屋頂，選擇紅色的天空。說(shuō)明這就不是顏色相似的問(wèn)題了。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 sky in my selection, which is exactly what i'm trying to avoid. this blue on blue isn't very helpful. our layer now is highlighted in red, even more striking is this red overly that covers our sky.?

3. 所以我們引入快速蒙版模式，給到視覺(jué)化呈現(xiàn)，房子改選的沒(méi)有選部分，天空不該選但是被誤選的部分。關(guān)注問(wèn)題區(qū)域，用B熱鍵調(diào)取前景白刷，涂抹紅色區(qū)域，漏選的紅色屋頂區(qū)域，如果需要調(diào)節(jié)刷子硬度。最好方式鋼筆工具勾選，而且該區(qū)域不需要調(diào)節(jié)曲率，快速蒙版模式允許摻入鋼筆工具選擇。用刷子涂抹內(nèi)部或Alt+Delete填充選區(qū)顏色。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 that's covered in red. i can zoom in and focus on problem areas. besides showcasing all selection issues. i also get a great way of solvign them. grab B brush tool with white as foreground color, i can start to paint over these red areas, red means it's not selected, and i want entire building selected. a much better approach would be the following get the pent tool and quickly click on a few times. we don't need any curves for specific region. close it off and right click make a selection. that's allowed in quick mask mode. exit quick mask mode either through hotkey Q or by pressing on icon in tool box,?

4. 需要指出的是方法上可以全選后，把小面積的天空用Alt移除選擇。另外，多邊形選擇和套索選擇工具遠(yuǎn)遠(yuǎn)好過(guò)快速選擇模式，所以在具體任務(wù)具體分析的時(shí)候選對(duì)工具。i could have used Alt to remove parts of sky if they're been selected by mistake, but polygonal lasso or pen tool would have been much better options. if that wan't the case and i want to get rid of sky , i would have approached it the other way around. work smarter not harder.

Select A Color In Photo?

選擇照片中的顏色

1. 本節(jié)解決的問(wèn)題如何從照片中選擇粉花，如何避免一個(gè)個(gè)粉花點(diǎn)擊費(fèi)力效果欠佳的過(guò)程。做選擇的目標(biāo)位了給編輯明確定位的。而魔術(shù)棒或快速選擇工具需要很多次點(diǎn)擊才可以選中花的細(xì)節(jié)。如何加速進(jìn)度呢，頂部菜單選擇-顏色范圍。下拉菜單中樣本選擇顏色，我們嘗試下其他選擇怎么不好，來(lái)證明為什么推薦樣本選擇顏色。select a color from a difficult image with the least amount of work possible with allow you to cut down time it takes. to select all flowers from photos, you'd first have to start with a selection so you'd first have to start with a selection so you'd 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. go to menu and click on select, now choose a color range.

2. 首先嘗試紅色樣本，可以看到左上角很多天空的顏色都被選進(jìn)來(lái)了，但是我們目標(biāo)選擇花朵，紅色樣本不合適。更換高亮的樣本，測(cè)試的方案是鼠標(biāo)到花朵上，光標(biāo)變成拾色器的樣子，移動(dòng)到天空，可以看到預(yù)覽框依舊顯示天空，也證明高亮模式并非最佳模式。first dropdown is currently, set at sample colors, but i can change it to reds, i the small preview window, everything that is white will be selected, we can see 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 gettign a bit of sky. shift mode to the color, this creates a selection based on what colors we grab from 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.?

3. 接下來(lái)是對(duì)話框底部的灰色天空，選擇后可以點(diǎn)擊花朵部分調(diào)節(jié)選區(qū)，在保存按鈕下面，有三種拾色器，被選中的部分是目前應(yīng)用的，剩下拾色器一個(gè)加色彩如同Shift熱鍵作用，另一個(gè)拾色器減色彩如同Alt熱鍵的作用。了解完對(duì)話框，操作方式，下面選擇灰色尺度，上面選擇顏色樣本，按住Shift，點(diǎn)擊花朵，可以看到預(yù)覽框中花朵逐漸增多。we'll focus is bottom area and click on this dropdown, choose gray scale, and this will now show you the preview directly on the canvas. click again somewhere over the flow, 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 it hotkeys shfit to add, alt to remove. 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 holing down Shift key, let's do that now by change preview to gray scale yet again, click on any flower, then repeat the process several times while using the shift key. notice how my selection is starting to grow.??

4. 談?wù)剬?duì)話框的模糊的功能，調(diào)大到200可以看到像是給花朵注入生命，這樣的意義，看清楚多選的枝葉，用Alt熱鍵去除多選的結(jié)構(gòu)。在勾選染色花束后，范圍滑塊才被激活，小范圍局限于花朵，大范圍廣到枝葉。這樣可以調(diào)節(jié)選區(qū)的樣本范圍。to further refine it, this fuzziness slider is a life saver, turn it up to about 150, you'll see how you get a much clearer image of what's going on. once you get hang 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 guy constantly swtich between adding to 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.?

5. 最后是下載保存的格式為.AXT格式，打開(kāi)后，看到螞蟻行軍標(biāo)記出的選區(qū)。畢竟好的選區(qū)才是編輯的前提。接下來(lái)可以調(diào)取曲線調(diào)節(jié)圖層，進(jìn)行調(diào)節(jié)，展示選區(qū)完美的重要性。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.?

Activity Remove Background?

移除背景

1. 本節(jié)處理的任務(wù)是橄欖球的草地背景換成夢(mèng)幻天空的背景。分為四步部，第一，移除背景；第二，添加新實(shí)色圖層；第三，創(chuàng)建真實(shí)的陰影；第四，創(chuàng)建貼圖效果；one you remove the background, two, add a new one through an adjustment layer, three, create a realistic shadow, four, create a vignette effect.

2. 首先第一步去除背景前提創(chuàng)建球體的選區(qū)，選擇工具個(gè)人優(yōu)選鋼筆工具，但是鑒于大多數(shù)人傾向選擇快速選擇工具，快速選擇工具球底部，選擇不少的草地，按住Alt移除不想要的草地，但是效果差強(qiáng)人意，不過(guò)球體弧度被選擇算是合格的。被選取球體放到透明蒙版上，避免不可逆性編輯；熱鍵B調(diào)取黑刷，特寫貼近球體邊緣涂抹。該效率證明不如鋼筆工具，換工具，熱鍵P鋼筆工具三下圈選出球體，好處可以確保平滑的表面和曲率。熱鍵Ctrl可以進(jìn)一步調(diào)節(jié)邊緣。右鍵做出選擇，彈出的對(duì)話框羽化0像素，確保保持平滑。黑刷移除不需要的邊緣。Ctrl/Alt+Delete填充黑色。the pen tool would be my first choice, but since a lot of people use quick selection tool. i'll grab that instead. 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. here's the footbal on a transparent background, not quite a perfect cut out, if you want the alternative, grab B black brush, starting painting, go over each area and slowly get closer to bulls ege. this won't be fast, nor give you great result. let's start from the left side with pen tool, i want to get the entire bottom half with just three clicks. this will ensure a perfectly smooth surface, i'll drag a lot towards the right side, so i can get a nice curve. you may need to use control to further adjust it, in case it's not going well at all. use ctrl z and retrace steps. leave the feather radius set zero pixles. make sure anti alias check. paint with a black brush to fill with black.?

3. 第二部添加實(shí)色，用80AFFF，放置圖層下面如果背景移除有任何問(wèn)題，實(shí)色都會(huì)暴露出來(lái)。那種情況回爐處理。let's creat a background for it with the help of an adjustment layer solid color, will fill our canvas with any color of our liking. note that adjustment layers in general, don't contain any actual pixels. they only modifying 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. let's say 80 AFFFF place it underneath our layer. this solid color will expose any problems if that's the case.

4. 第三部創(chuàng)建陰影，工具欄選擇橢圓形工具，陰影比球體小，放置球體下面，水瓶居中，陰影圖層轉(zhuǎn)化為智能圖層，可以用過(guò)濾-模糊-高斯模糊-50像素，熱鍵G梯度工具，調(diào)取默認(rèn)前后景黑白色，選項(xiàng)欄的梯度過(guò)濾有幾種選擇方案，我們選擇放射性梯度。因?yàn)樾枰交^(guò)渡的效果。陰影如果不按Shift做不到不偏不倚，偏投陰影或太小的陰影顯得不真實(shí)。let's create a shadow, so it won't see like its 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, thsi si so we can adjust upcoming filter. apply a blur, specifically a gaussian blur. use tope menur for that. we're going to get the gradient tool, with hotkey G, you're looking for this preview here, the gradient top has multiple ways of working. we want a radial gradient. hold Shift you'll drag in a perfectly straight line you might end up with centered shadow.?

5. 最后一步貼圖效果，曲線調(diào)節(jié)圖層，屬性面板拖拽曲線中部，讓色彩變暗，調(diào)節(jié)刷子硬度50%，用2000的大刷子，移除球體周圍的效果。an adjustment there at the top of layer stack. choose curvers from properties panel, drag this one down somewhere near the middle, this darken everything. let's say hardness somewhere around 50%, size over 2000. click on ball and brush in circular pattern.?

Select And Mask Hair?

扣頭發(fā)絲

1. 模特?fù)Q背景，模特的頭發(fā)絲如何不含上一張背景的雜色，又可以完美的保留頭發(fā)卷曲部分呢，解決方案先暴露需要處理的點(diǎn)，然后處理。認(rèn)識(shí)下PS老版本的精修邊界，新版本的選擇和蒙版的功能吧。任意一個(gè)選擇工具都可以調(diào)取選擇欄的選擇蒙版的功能。潔面變化了，出現(xiàn)了左側(cè)工具欄，五個(gè)工具，分別是快速選擇工具，精修工具，套索工具和磁性工具。接下來(lái)重點(diǎn)介紹右側(cè)功能特征的作用和意義。remove the model 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, if you focus on hair, you can see there're few strands left out. the goal is to get them back with minimal efforts. PS give us completely new workspace called select and mask. that helps us improve our selection. in previous release of ps was called refine edges. if you have this button availabe in option bar, grab any selection tool that will give you this feature. alternative you can use hote key Alt Ctrl R once i click it, my workspace changes here, on the left side, you see we only five tools. quick selection tool, refine edge brush, lasso tool ,magnetic tool, hand zoom tool. the right side is packed full of settings and features. some of the more important than others in thsi case.?

2. 首先是背景圖的切換暴露需要處理頭發(fā)邊緣殘留圖層。設(shè)置不透明度，勾選智能半徑，半徑滑塊幫助拓展選區(qū)的用處，避免遺漏的細(xì)節(jié)。比如半徑滑塊調(diào)大最大值250像素，可以看到默認(rèn)的暴露頭發(fā)邊緣殘留前背景圖。如果關(guān)閉，可能導(dǎo)致頭發(fā)邊緣精致的卷曲丟失掉。結(jié)論是智能半徑應(yīng)該勾選。what's great is that you can adjust opacity of viewing mode so that you can get a better grasp of what's going on this. 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 issues. if i crank radius to its maximum value 250 pixles we can see it did a decent job at eliminating those white spots caused by original background. when you're dealing with hair fur by turning smart radius on, we can see how we're getting back some details which would have otherwise lost. so without smart radius, this body of hair becomes translucent, that's less than ideal.?

3. 接下來(lái)展示邊緣的功能，勾選后，再調(diào)節(jié)半徑，可以看到頭發(fā)邊緣需要處理部分區(qū)域變大?，F(xiàn)在把半徑調(diào)節(jié)到零。測(cè)驗(yàn)?zāi)：陀鸹诳垲^發(fā)絲這用到用不到，因?yàn)槲覀冃枰┞秵?wèn)題，不需要對(duì)比鮮明，也不需要掩飾問(wèn)題。所以模糊 羽化 對(duì)比三個(gè)功能可以不用理會(huì)。if you're not sure what value you need to use, go to top and check show ege feature, by enableing it, you can see the area where ps will look for extra hairs if radius zero, you wouldn't see anyting. but as i sowly increased it, you can see how this region grows. smooth and feather are two settings, they have no place here because we want to get all these fine details in our end result. there's little place where the contrast shows up i'll skip this feature.

4. 接下來(lái)是轉(zhuǎn)變邊緣的滑塊，調(diào)到最大可以看到問(wèn)題暴露明顯，用精修工具處理掉。再把轉(zhuǎn)變邊緣滑塊居中調(diào)節(jié)。最后調(diào)節(jié)邊緣的刷子。建議多點(diǎn)擊幾次，局部一點(diǎn)點(diǎn)的修改。最后瀏覽模式選擇在圖層上，勾選凈化顏色。最后用頻率調(diào)節(jié)蒙版，測(cè)試選區(qū)的。此時(shí)的轉(zhuǎn)化邊緣滑塊可以設(shè)置到20-50%。its a good way to reveal even more of those rebel hairs by sliding it to right we're going our selection. this reveals more of that white highlights, but that can be edited out. i'll paint a bit around her hair, you're eating into selection, it's similar to what we did in our selection exercise, i'll refine edge brush from pen tool box, i'll start painting all around contour to bring back some of messy hair, it's best to patch one area at a time. 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, enable decontaminate color from the bottom.?

Channel Selections?

通道選擇

1. 本節(jié)內(nèi)容講述RGB不同顏色通道，在同一張照片對(duì)應(yīng)不同的側(cè)重點(diǎn)，適用于復(fù)雜選擇。拿斑馬紋舉例子，如何提出掉背景，只剩下一條條的條紋進(jìn)行調(diào)節(jié)顏色等編輯。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 hightlight various parts of photo. this can help us create complicated selections that would have been otherwise very hard to pull off. i'd like to isolate black lines and work on them alone.?

2. 具體通過(guò)Ctrl+I調(diào)取水平對(duì)話框，輸入水平下面左中右三個(gè)滑塊，右側(cè)滑塊推向左側(cè)，背景消失。左側(cè)滑塊推向右側(cè)，會(huì)出現(xiàn)鋸齒的條紋，建議留在中間。這樣我們選擇了黑色線條，如果下載我們只會(huì)發(fā)現(xiàn)黑線條，看不到白色背景的。by using levels command. ?through Ctrl I. you'll get this window, tab right handle and put it towards the left side, you can see background fades away. for the left side, i want to crank up dark lines because my channel selection is going to be that much better. as i go back and forth. you don't want it too far to right.?

3. 為檢測(cè)靈活度，用實(shí)色調(diào)節(jié)，不同的顏色，對(duì)應(yīng)不同的條紋。再次驗(yàn)證好的選擇是好編輯的前提。we want the complete opposite, select invert, you can't see from marching ants that we've made a big change. now we have a fantastic selection of black lines. add a solid color adjustment layer, choose any color whatso ever hit okay. the great thing is you can change color on fly double click it.?

Review?

回顧

• 選擇不要忽略套索工具，鋼筆工具功能很強(qiáng)大。選區(qū)的意義是好編輯的前提。i still keep an open mind when i'm presented with a new project because each image is different. you never stop improving selection skills.?
