Selections Explained?

解釋選擇工具

1. 字幕框選工具。拖拽框選之內(nèi)范圍內(nèi)繪畫(huà)編輯算數(shù)，縱使編輯涂抹到框選之外的，不留痕跡，換言之，編輯不影響框選外，只對(duì)框選內(nèi)起作用。i'll drag out a selection, all these pixels that are contained in box. now the subject of my edits, nothing else will be affected. no matter how much i try to influence surrounding area, because it allows me to pinpoint where i want to work by isolating certain areas, colors, objects so on.?

2. 螞蟻環(huán)線，仔細(xì)看看框選圍起來(lái)形狀，用來(lái)定義框選范圍的。This intimate black line that constantly moves around defines selection. it's usually referred to as the matching ants.?

3. 有好幾種選擇方式。大致上，我們用框選，套索，快速選擇，魔術(shù)棒，鋼筆工具。in general, we'll use the marquee tool, lassol tool, quick selection tool, magic wands, pen tool.

4. 當(dāng)我們繼續(xù)還用于項(xiàng)目的時(shí)候，ctrl+D去選擇?；蛘咧鞑藛巍斑x擇-去選擇”。you need to deselect with Ctrl+D, go to top menu, from select, go to deselect.?

5. 如果ctrl+S不小心同事按住Ctrl+A時(shí)候，就是同時(shí)選中畫(huà)布了，但是如果距離太近看不到選中畫(huà)布了，執(zhí)行下一步ctrl+T變形，似乎快捷鍵沒(méi)發(fā)揮作用，這時(shí)候應(yīng)該想到是不是自己不小心把畫(huà)布選中了。這樣Ctrl+0退出，Ctrl+D去選擇畫(huà)布。然后針對(duì)對(duì)象繼續(xù)變形選擇。i'll add a rectangle on screen and say, i've used Ctrl+S and inadvertently hit Ctrl+A as well. now my canvas is selected, but i have no idea because i'm tool zoomed in. now i'll try to transform this rectangle with Ctrl+T, but nothing happens. because i have an active selection. photoshop doesn't let me enter free transform mode. when i double zoom out with Ctrl+0, and see if you have a selection active, in that case use Ctrl+D.

6. 羽化到0%？可以在選項(xiàng)欄選擇羽化工具，創(chuàng)建新圖層，可以用Alt+Delete，填充黑色，然后選項(xiàng)欄羽化，就可以看到羽化黑色，再羽化到50%，就可以看到柔化的邊緣平滑的轉(zhuǎn)變。selections can be feathered through this area from the optional bar, without a feather. i'll drag a selection and i'll create a new layer. now i'll use?Alt+Delete, so i can fill it with black. there's nothing spectacular going on, if i increase feather value to 50 pixels, i repeat the process, the edge are soft and gradual smooth transition.

7. 為什么保持羽化50%狀態(tài)下，出現(xiàn)錯(cuò)誤提示呢？因?yàn)榕c你選擇區(qū)域像素比較，羽化像素太高了，選的像素不夠羽化的像素呢。建議羽化到0，這樣可以選中范圍，避免出現(xiàn)羽化調(diào)到很高，怎么選都提示錯(cuò)誤對(duì)話框的情況。i'm constantly getting error. that's because feather value is too high, compared to region you're trying to select. when you're trying to select, there aren't enough pixels for program to feather, thus it isn't able to make it happen. so always take the feather back down to zero pixels.?

8. 創(chuàng)建選項(xiàng)區(qū)的好處，比如風(fēng)景畫(huà)對(duì)大地對(duì)天空不同區(qū)域用選擇框保護(hù)，選框內(nèi)的修改相互不干擾。to sum up, selection help you target specific areas with precision. they give you comfort by setting up boundaries, you can't go across because each image is different.?

變形選擇

1. 僅作用于光柵圖層。首先如果你用V移動(dòng)工具選擇，可以通過(guò)剪切拖拽選出來(lái)，展示棋盤(pán)背景，這是因?yàn)閳D層下面什么都沒(méi)有。為什么會(huì)出現(xiàn)這種情況？因?yàn)檫@是同一個(gè)圖層，剪開(kāi)一塊，修修補(bǔ)補(bǔ)的。first, if you switch to move tool by V with an active selection on canvas, you can cut out that area by clicking and dragging. this will reveal cherkered background, there's nothing underneath layer, this only works on raster layer. why isn't helpful in format? because this area that was repositioned is still on the same layer, let's undo, this time use Ctrl J.

2. 這次用復(fù)制圖層，剪切一塊復(fù)制到另一個(gè)圖層，下面棋盤(pán)格式不會(huì)暴露出來(lái)了。this time more useful. this command is used to duplicate a layer or folder. here it extract this selection to a new layer. this is much more useful.?

3. 用F12反轉(zhuǎn)，或者主菜單“文件-反轉(zhuǎn)”，或者畫(huà)布任意空白處右鍵選擇反轉(zhuǎn)，這種是選擇小區(qū)域，反轉(zhuǎn)等于選擇大區(qū)域。就是隔離一小塊區(qū)域，選擇剩下一大片區(qū)域用的。F12 revert, if the hotkey doesn't work. go to top menu, and click on file -revert, with another selection active, you can right click it and select everything else on the canvas, through this select inverse option. this is fatastic for situations where you have to affect a large image, except for the small part.?

4. 羽化，可以在選項(xiàng)欄里選擇，可以在任何選擇后，右鍵下拉菜單選擇羽化。any selection can be feathered, even if you didn't use this in put field from the optional bar, no matter what tool you used to create a selection, you can right click and choose feather.?

5. 填充顏色，用ctrl/alt+Delete或者Shift+F5填充對(duì)話框，選擇顏色。as we previously discussed, if you want to see its effect, you'll have to fill this area with color, use Ctrl or Alt along with delete key, alternatively, you can use Shift F5, and this bring up the fill command, choose any color, you'll now see feather effect.?

6. 選擇-調(diào)節(jié)-邊界-縮小。這三個(gè)選項(xiàng)是在一起的，頂部菜單選擇調(diào)節(jié) 拓展，可以輸入像素?cái)?shù)值，這是PS如何加入到當(dāng)前選項(xiàng)里，對(duì)話框輸入50看看拓展到效果。if i want to include another two or three pixels in the selection. go to top menu and click on select from this list, choose modify expand, from this pupup input your pixel value. this is how much ps will add all around your current selection. here's how if go with something generous like 50 pixels so you can see difference.?

7. 選擇-調(diào)節(jié)-縮小“應(yīng)用效果作用于畫(huà)布邊界”。如果你選擇好幾個(gè)圖層，該指令也沒(méi)有熱鍵，所以去主菜單“選擇-調(diào)節(jié)-縮小”，該復(fù)選框勾選上，僅適用于你選擇整個(gè)畫(huà)布情況下。this works the other way around. you can contrust your selection, just in case you selected too much of your layer, this command doesn't have a hotkey either. so we'll have to use that top menu yet again, select modify contract, enter value and note this "apply effect at canvas bounds" is helpful only if you're using Ctrl+A to select entire canvas.

8. 選擇-調(diào)節(jié)-邊界，出現(xiàn)類似畫(huà)框一樣，填充上顏色，很漂亮。one last feature that creates and interesting look is border, this lies in the same menu system. let me bring it up and i'll show you how easy it is to get a nice effect going. now it's applied. here i'll fill it with white.?

9. ?“自由變形”VS“選擇變形”異同點(diǎn)。除了字面含義還有哪些不同呢？let me clear up any potential confusion if i right click, you will see two transform options, free transform and transform selection. their names tell their story. but i'd like explain it just to be safe.?

10. 熱鍵Ctrl+T調(diào)取自由變形，可調(diào)節(jié)選擇區(qū)域的大小，因2019版本默認(rèn)鎖定比率的調(diào)節(jié)大小，熱鍵shift不維持橫寬比。free transform is what you get when you press Ctrl+T, thus if you selected from this list, you'll be able to resize the selected area. please be aware that my selections aspect ratio is being perserved by default. that's because i'm using CC2019. hold down shift key, disable that new behavior, now you're free to adjust it however you want.?

11. 老版本的2018以及以前的，需要按住shift才能維持橫寬比。和新版2019的功能相反的。using old version when you want to resize your selection, you have to hold down shift to maintain its aspect ratio. so depending on your version.?

12. 轉(zhuǎn)化選擇Ctrl+T調(diào)出調(diào)節(jié)的抓手來(lái)，調(diào)節(jié)的并不是實(shí)際的像素，右鍵獲得調(diào)節(jié)的選項(xiàng)。once you enable transform selection, you'll get similar handles like you get with Ctrl+T. only this time you're only adjusting your selection and not your actual pixels. as you right click, you'll get all sorts of options we've talked about already.

13. 最常用的選項(xiàng)是扭曲。看鼠標(biāo)到調(diào)節(jié)的邊緣就變化了，按住Ctrl鍵，調(diào)節(jié)邊緣又變化了。 用于手動(dòng)調(diào)節(jié)不規(guī)則形狀。as i go over my edge, my cursor changes, PS tells me i can grab this area and full around with it, but if i hold down Ctrl key, this change my cursor yet again. i can adjust this selection to all sorts of irregular shapes in handy.

Modify Selections?

調(diào)節(jié)選擇

1. 兩種主要的框選工具都是不可或缺的。有四種，但是常用的是前兩種。矩形選框和橢圓選框。the marquee tools are in dispensable for make. there're four in total but everybody uses first two, the rectangular marquee, elliptical one, the other two are useless and pointless.

2. 矩形框選工具的選擇。熱鍵是M，選擇拖拽新選區(qū)域，Ctrl+D去選擇。the hotkey is M, click and drag, you'll have a rectangular selection. new selection will appear. Ctrl+D to deslect the selection area.

3. 選項(xiàng)面板四個(gè)按鈕分別介紹下鼠標(biāo)形狀和切換熱鍵。in this option bar, you'll notice four icons, and one of them is active. let's explore them one by one.

4. 第一常規(guī)模式，畫(huà)選區(qū)域的，光標(biāo)沒(méi)特點(diǎn)，this 1st one is the normal mode that creates a new selection every time you drag.

5. 第二加入模式，區(qū)域疊加的，不管區(qū)域相連與否，光標(biāo)帶加號(hào)。 the 2nd plus icon. when used, will automatically add to you selection. no matter where you draw on canvas. it can be next to it, or it canbe somewhere completely unrelated. my cursor has a plus symbol next to it.

6. 第三移除模式，區(qū)域相減的，光標(biāo)減號(hào)。3rd icon, removes part of your selection. its hotkey is Alt, notice the minus symbol on your cursor.?

7. 第四交叉模式，留下交集點(diǎn)，但是很少用。光標(biāo)剪刀。this is rarely used. few people use it. it's hotkey is both Alt and Shift,?and you recognize it through this X symbol. this removes every part of selection except this intersection.?

8. 繪制大小參考數(shù)值怎么看？黑框內(nèi)寬度和高度的數(shù)據(jù)?；蛘哌x項(xiàng)欄輸入確切的像素?cái)?shù)據(jù)。you can see size of your selection while you draw, W stands for width and H for height. so if you want it 300 by 400 pixel selection. you could use it like that.

9. 選中框內(nèi)進(jìn)行位移。note that if you have a marquee selected and you click inside and drag, you'll be able to reposition it. that only happen if you're inside the selection.?

10. 先點(diǎn)擊后加Shift,?畫(huà)個(gè)中規(guī)中矩正正方方方框。if you click add shift, you will constrain its aspect ratio. you'll get a square.

11. 先按shift, 點(diǎn)擊拖拽，可以調(diào)出2號(hào)?選框工具，給現(xiàn)有選框加入新選框。if you hold down modifier key shift, click and drag, you'll change marquee mode to 2nd one, which adds to existing selection.?

12. 四面拓展拖拽Alt ,中規(guī)中矩的從開(kāi)始位置拓展Alt+Shift。click drag hold Alt in your selection will expand on all sides. if i move to the left, this election will go to right at the same time. ?if you click drag and hold both Alt and Shift, it will grow your selection uniformly starting where you clicked.

13. 固定大小風(fēng)格。比如輸入精確的價(jià)值。??建議風(fēng)格下拉菜單選擇并保持“正?！?。如果繪制選項(xiàng)內(nèi)容，釋放鼠標(biāo)，按住空格鍵，這樣移動(dòng)的選框內(nèi)容。但是如果不釋放鼠標(biāo)，按住空格鍵拖動(dòng)，移動(dòng)的是畫(huà)布。另外一點(diǎn)，按住空格鍵別撒手哦，不然選框也不隨心所欲的移動(dòng)。fix size is useful when you want to input some specific value. simply click on that will create a selection, based on input.i recommend you keep style set at normal. finally, if you click and drag, but don't let go and you press space bar key, you will be able to freely reposition it on the canvas. ?note that you have to keep space bar down, otherwise it won't work.?

Elliptical Marquee?

橢圓形框選工具

1. 為什么“保持光滑”復(fù)選框需要被勾選上？因?yàn)楫?dāng)你放大看差別的時(shí)候，一個(gè)鋸齒狀的，一個(gè)平滑的，大部分人選擇平滑效果的。so i recommend you always have the "anti-alias" checked. the smoothing of the edges. and it doesn't apply to straight one like the rectangular marquee tool create.?

2. 用shift創(chuàng)建圓環(huán)，用F5填充黑色。可以編輯填充。可以重復(fù)該過(guò)程，檢測(cè)平滑選項(xiàng)是否開(kāi)啟。to see the difference, first you'll create a circle with the anti-alias off, hold shift to have perfect around. then you shift F 5 to fill it with black. you can also go to edit fill. now repeat the process, but first check the anti aliasing option up top.?

3. 解決的痛點(diǎn)是？如果想選這區(qū)域，如果不確定是不是到頂部?？梢赃x擇，去選擇。if i want to select this area, i need to go some where in the upper left, though i'm not sure where i have to constantly hit Ctrl D to deselect and then remark my selection.?

4. 移動(dòng)左上并且拖拽，別松鼠標(biāo)按住空格，現(xiàn)在可以選擇位置并且對(duì)齊。從左側(cè)頂部，釋放掉控股，拓展選擇。按住空格鍵移動(dòng)到位置。這是相對(duì)好的方式。go to the upper left and drag. don't let go and hold space. now you can move selection position it align it in one place. the top of left side, let go of space and expand your selection some more then hold space and move it into place. this is the best way to go about it.?

5. 另一個(gè)選擇并非最有效的。用Alt shift拖拽，Alt幫助從原點(diǎn)拓展，shift幫助創(chuàng)建完美的圓，中心點(diǎn)盡可能接近客體中心。最后按住空格，移動(dòng)客體。use the shift+alt. Alt make the selection expand from point of origin. shift helps you create perfect circle will make your selection expand from point where you clicked. take your best guess where centered of object. that's the other option you have hold three keys. hold the space bar down in total. now you reposition it. ?

練習(xí)題答案

1. 其中第一個(gè)，M調(diào)取橢圓形框選，放大后，點(diǎn)擊同時(shí)按“Alt+Shift”這樣一個(gè)盡可能沿著中心覆蓋該物體，然后用空格鍵移動(dòng)位置。最后復(fù)制到白版上。Mgrab the elliptical marquee and zoom in really close, now approximate its centers click and drag, don't let go of your mouse, click and press "Alt+Shift" at sametime. this will allow you to move your selection perfectly covers circle. place this duplicate above white layer and enable it.?

2. 餅形圖在同樣操作鎖定橢圓，同時(shí)借助矩形變形工具抓手拖到位，到位的標(biāo)準(zhǔn)是矩形內(nèi)嵌套橢圓形。enlarge modifier key. as you enlarge it, you may want to release one of modifier keys from time to time, see if that helps in anyway. once you're happy with that outcome.?

3. 半圓先選中整個(gè)圓，再用矩形剪掉下半圓。需要注意要點(diǎn)1??橢圓選中情況下切換到矩形選框，在開(kāi)始拖拽前按住Alt，移除掉不需要的橢圓下半圓。2??矩形可以選中離著半圓邊界往外，不要選在半圓邊界內(nèi)。3??原因是你還可以二次選擇矩形專門(mén)切到半圓內(nèi)平行線。 1??your elliptical selection will remain active. now hold Alt before you start dragging. you'll need to grab entire region in order to remove it. because i'm holding Alt, my cursor has htis minus symbol attached to it. you can also use space bar key you can place it exactly where you need it. 2??say it's safer to leave a few extra pixels rather than to cut into yellow shape. that's because 3?? you can always create another rectangular selection with Alt key and remove that extra space.?

4. 圓形右上方方形的結(jié)合。圓形框選后右鍵變形調(diào)節(jié)，按住shift不偏不倚框選方形。i'll draw out an initial selection with elliptical marquee, right click and i'll choose transform selection. with the help of handles, i can adjust it without problem. now for the circle, it is standard at this point, now for square part, i switch to rectangular marquee, i'll use shift before i click on canvas, that will add to selection. i can copy it and place it at the top of layers panel.

5. 粉紅色方形中間白色圓形。粉色方形擺對(duì)位置，橢圓形框選后做減法。 i'll initially use rectangular marquee to get a large pink shape. after pink rectangular is properly positioned. i'll switch to elliptical marquee, hold down Alt get minus symbol, spar bar move around until it right. ?
