1. 單反相機(jī)ef是什么意思

1、EF：全畫幅鏡頭，最常見的佳能鏡頭類別，可以用在EOS系列的膠片單反相機(jī)、全畫幅數(shù)碼單反相機(jī)、APD-H（系數(shù)1.3）和APS-C畫幅（半幅相機(jī) 系數(shù)1.6）數(shù)碼單反相機(jī)上。

2、EF-S：APS-C畫幅鏡頭，專為APS-C單反相機(jī)設(shè)計的鏡頭，俗稱半幅或者殘幅，傳感器面積是全幅的40%，價格便宜。同樣也是我們較常見的佳能鏡頭。

3、TS-E：移軸鏡頭，個人理解就是可以把鏡頭掰彎，然后抵消透視和改變合焦范圍，用于建筑攝影等方面。

4、MP-E：微距鏡頭，專門為了把蒼蠅腿上的毛拍的很清楚而生的鏡頭。

2. 單反efs是什么意思

1、外觀不同

EF鏡頭的安裝定位點標(biāo)注為紅色圓點，EF-S鏡頭的定位點是白色方塊。并在EF-S鏡頭尾部增加了塑料突起，確保無法安裝在全畫幅機(jī)身上。

2、價格不同

EF-S鏡頭輕便、小巧，價格低廉，EF鏡頭價格相對更貴一點。

3、可安裝的機(jī)身不同

（1）EF系列鏡頭為佳能標(biāo)準(zhǔn)卡口的鏡頭，可以使用在它全系列膠片單反和數(shù)碼單反（包括全幅和非全幅）上，佳能的EF鏡頭可以適用所有的佳能EOS系列的機(jī)身（包括膠片單反機(jī)、數(shù)碼全畫幅和非全畫幅單反機(jī)）。

（2）EF－S鏡頭，廣角段更大，使得乘上1.6倍系數(shù)后還具有一個可以接受的廣角。EF-S系列鏡頭為佳能為APS-C幅數(shù)碼單反生產(chǎn)的為了得到更大的廣角端的數(shù)碼專用鏡頭，EF-S鏡頭不能用在全幅機(jī)子上，它的設(shè)計上尾部進(jìn)入機(jī)身比較多，安裝在全幅機(jī)子上可能導(dǎo)致反光板損壞。

3. 相機(jī)ef和rf什么意思

佳能rf和ef鏡頭區(qū)別：

1、主體不同

ef鏡頭：是對焦電子化理念的全面發(fā)展；RF鏡頭：是系統(tǒng)開發(fā)的核心，EOS R系統(tǒng)有望成為一個不斷發(fā)展的影像系統(tǒng)。

2、特點不同

ef鏡頭：相機(jī)與鏡頭中的微芯片通過電子信號進(jìn)行信息交流，驅(qū)動鏡頭中的電機(jī)進(jìn)行對焦；RF鏡頭：具備內(nèi)徑為54 mm的大口徑以及短后對焦距離，大大提高了光學(xué)設(shè)計的靈活性，使其能夠開發(fā)出理想的鏡頭。

3、優(yōu)勢不同

ef鏡頭：采用“相機(jī)測距+鏡頭內(nèi)置電機(jī)驅(qū)動”的方式，相機(jī)與鏡頭之間不存在機(jī)械通訊系統(tǒng)；RF鏡頭：旨在進(jìn)一步拓展攝影領(lǐng)域，為用戶提供更理想的鏡頭，采用全新標(biāo)準(zhǔn)卡口，提高了光學(xué)設(shè)計的自由度和系統(tǒng)開發(fā)的可能性。

4. 單反相機(jī)f是什么意思啊

建議你查說明書，上面有詳細(xì)的圖標(biāo)說明，例如P是P檔也就是自動檔，由相機(jī)自身控制曝光參數(shù)，底下的F3.5（光圈值）就是由P檔計算出的曝光組合中的參數(shù)之一。

5. 相機(jī)的ef是什么意思

佳能相機(jī)鏡頭數(shù)字表示的意思如下：拿佳能的EF-S18-200mm1:3.5-5.6IS鏡頭來舉例吧。 EF-S指的是佳能口（為非全副單反而設(shè)計的）；18-200mm指的是焦段；1:3.5-5.6指的是最大光圈，為3.5-5.6，浮動光圈，根據(jù)焦段最大光圈也不同；IS代表的是佳能的圖像穩(wěn)定器，也就是防抖；鏡頭上一朵花后的數(shù)字表示最近對焦距離0.45米；還有鏡頭前數(shù)字72MM為鏡片直徑。

6. 相機(jī)efc是什么意思

PS一般指Adobe Photoshop，是由Adobe Systems開發(fā)和發(fā)行的圖像處理軟件。修圖也即修改圖片，將圖片進(jìn)行一定的處理，修調(diào)，從而達(dá)到需要的效果。

了解界面

菜單欄

頂部區(qū)域是菜單欄，將Photoshop所有的操作分為九類，除了【幫助】選項，共九項菜單。如編輯、圖像、圖層、濾鏡。

工具屬性欄

藍(lán)色部分稱為工具屬性欄，左側(cè)工具欄中的每個工具選項都對應(yīng)不同的工具屬性(如下圖)，所以選擇不同的工具或選擇不同的對象時出現(xiàn)的選項也不同。

工具欄

紅色區(qū)域中的豎長條稱為工具欄，也稱為工具箱。對圖像的修飾以及繪圖等工具，都從這里調(diào)用。幾乎每種工具都有相應(yīng)的鍵盤快捷鍵。

浮動面板

PS的的右上方是浮動面板區(qū)域。浮動面板是Photoshop中非常重要的輔助工具，它為圖形圖像處理提供了各種各樣的輔助功能。每個浮動面板都可以用鼠標(biāo)進(jìn)行拖拽隨意放置符合你工作慣性的地方。

標(biāo)題欄

標(biāo)題欄顯示的是對工作區(qū)命名。

狀態(tài)欄

包含四個部分，分別為：圖像顯示比例、文件大小、浮動菜單按鈕及工具提示欄。

圖層工具欄

包含：圖層關(guān)聯(lián)、圖層樣式、蒙版、濾鏡、圖層組、圖層、刪除圖層，這7大功能。

工作區(qū)

Photoshop可以同時打開多幅圖像進(jìn)行制作，圖像之間還可以互相傳送數(shù)據(jù)。在打開的圖像間可通過菜單【窗口】底行的圖像名稱切換，也可以快捷鍵【CTRL+TAB】完成圖像切換。

工作區(qū)灰色的區(qū)域稱為工作區(qū)，用來顯示制作中的圖像。Photoshop可以同時打開多幅圖像進(jìn)行制作，圖像之間還可以互相傳送數(shù)據(jù)。在打開的圖像間可通過菜單【窗口】底行的圖像名稱切換，也可以快捷鍵【CTRL+TAB】完成圖像切換。

小竅門

具體每一個工具的名稱，只要把鼠標(biāo)移動到該工具上，旁邊就會出現(xiàn)工具名稱。

修圖方法

使用多個圖層

在工作中盡可能地使用多個圖層，圖層的作用，就是為了方便后期更改，否則Photoshop后期的修圖和合成很難一次成型，為了讓作品更完美，創(chuàng)作過程中會反復(fù)修改，因而最好在每一個關(guān)鍵的部分都新建一個圖層。

圖層透明度的修改，一般都是在圖層上方有個透明度，拉下圖層上放的透明度滑塊就可以修改了，還有更快的方法，就是選擇圖層，按下鍵盤數(shù)值可以直接修改透明度，按下數(shù)值1就是修改10%的透明度，按下數(shù)值2就是修改20%的透明度，按下數(shù)值3就是修改30%的透明度，以此類推，可以快速改變圖層透明度。

多使用蒙版

能想到刪除和擦除這兩個動作的地方，都可以用蒙版來代替。

刪除和擦除是一種有破壞性的編輯，它們對于圖層內(nèi)容的傷害是不可逆的，而蒙版只是暫時隱藏選中的圖像部分。好處在于，可以隨時地對該部分圖像進(jìn)行繼續(xù)隱藏或恢復(fù)等操作，并且無論操作多少遍，都對原圖沒有任何的破壞，蒙版是一種無損的編輯方式。

蒙版的使用方式

首先第一步打開素材，點擊快速蒙版按鈕。

使用畫筆工具，大致選中照片中人像。

再次點擊快速蒙版，退出快速蒙版模式，按住Ctrl+shift+I鍵進(jìn)行反選。

在頂部菜單欄中執(zhí)行“選擇”-“選擇并遮住”（老版本PS叫做調(diào)整邊緣）。

接下來我們把透明度設(shè)為100，邊緣檢測半徑設(shè)為60，移動邊緣設(shè)置為15，選中凈化顏色數(shù)值設(shè)置為57。

接下來選中調(diào)整邊緣畫筆工具，涂抹帶有背景圖層的位置，設(shè)置數(shù)值和效果。

多利用智能對象和智能濾鏡

在對圖像進(jìn)行放大、縮小、扭曲、旋轉(zhuǎn)和變形等操作時，都會有或多或少損失一部分畫質(zhì)，而將普通圖層轉(zhuǎn)化為智能對象后，再進(jìn)行上述操作時，將保留圖像一切的原始特性，不會對圖像的原始畫質(zhì)造成任何的破壞，因而，智能對象也是一種無損的編輯方式。

右擊圖層，跳出來的窗口之后，選擇“轉(zhuǎn)換為智能對象”。

一些濾鏡沒有預(yù)覽功能，只能設(shè)置一次參數(shù)看一次效果，如果不滿意就得從頭開始，使用智能濾鏡后就可以很方便地修改濾鏡的參數(shù)，不透明度和混合模式等。

多利用調(diào)整圖層

當(dāng)需要對圖層的色階、亮度，曲線和顏色等做出調(diào)整時，如果直接在原圖上修改，那么后期將很難再進(jìn)行調(diào)整，調(diào)整圖層是一個獨立圖層調(diào)整，圖層是一個獨立圖層，在這個圖層上可以反復(fù)進(jìn)行多次的無損調(diào)整，最終效果不滿意，還可以直接刪除這個調(diào)整圖層，然后重新添加一個調(diào)整圖層，就可以繼續(xù)對原圖層進(jìn)行調(diào)整，這個過程對原圖層是沒有任何影響的。

多使用快捷鍵

使用快捷鍵，是最能提升工作效率的操作，這就好比設(shè)置的特殊電話號碼，按“1”直接就是打給父母，按“2”就是直接打給妻子。

快捷鍵位置：

點擊打開之后，界面如下：

摳圖技巧

1、鋼筆工具摳圖

鋼筆工具適用于外形復(fù)雜、不連續(xù)、色差不大的圖，加工精度高、純手工放大邊界點來摳圖，先將需要摳圖的素材拖到ps中。

利用快捷鍵“Ctrl+J”復(fù)制一層圖層。

選擇“鋼筆工具”。

接著在需要摳圖的地方描點。

將需要摳出來的部分都圈住后點擊鼠標(biāo)右鍵，選擇“建立選區(qū)”。

調(diào)整羽化半徑，根據(jù)描點距離圖片的距離選擇，勾選“消除鋸齒”后點擊“確定”。

然后建立好選區(qū)，可以利用快捷鍵“Ctrl+C”復(fù)制選區(qū)的圖層。

在一個空白圖層利用快捷鍵“Ctrl+V”粘貼即可完成摳圖。

2、魔術(shù)棒摳圖

魔術(shù)棒摳圖適用于圖像和背景色色差明顯，背景單一，圖像邊界清晰的素材，首先將圖片素材利用ps打開

接著點擊“魔棒工具”

然后調(diào)整容差值為“32”，勾選“連續(xù)”和“消除鋸齒”

然后利用魔棒工具點擊圖片的背景區(qū)，選擇一個區(qū)域后點擊鍵盤上的刪除鍵

把背景全部刪除后即可完成摳圖

3、色彩范圍摳圖

色彩范圍摳圖適用于背意景色單一，圖像分明、背景無色彩的素材。首先利用Ps打開圖片素材

接著點擊“選擇”選項卡

然后在彈出的選項中選擇“色彩范圍”

然后用顏色吸管拾取背景色

接著勾選“反相”并點擊“確定”

然后會建立一個選區(qū)

最后利用快捷鍵“Ctrl+J”復(fù)制一層圖層即可完成摳圖

4、磁性索套工具摳圖

磁性套索摳圖適用于圖像邊界清晰，磁性索套會自動識別并黏附在圖像邊界上，如果邊界模糊處放大了再放置這樣就更精確，首先利用ps打開圖片素材

然后選擇“磁性套索工具”

接著將鼠標(biāo)移到圖像邊界處，然后磁性套索工具自動識別并黏附在圖像邊界上

等磁性套索工具閉合后就將整個圖像都選中了

然后利用快捷鍵“Ctrl+J”復(fù)制一層圖層即可完成摳圖

5、羽化法摳圖

羽化法摳圖適用于邊界清楚的素材，首先利用ps打開圖片素材

然后選擇“套索工具”

接著利用套索工具將圖像選中

然后點擊鼠標(biāo)右鍵，選擇“羽化”

根據(jù)套索與圖像的距離調(diào)整羽化半徑，距離較近就調(diào)小點，如調(diào)整羽化半徑為“5”后點擊“確定”

然后就將圖像摳出來了，但是周圍有不需要的部分，可以利用橡皮擦工具擦去

點擊選擇“橡皮擦工具”

將周圍多余的部分擦去即可完成摳圖

6、蒙板摳圖

蒙板摳圖快速并直觀適用范圍廣，首先利用ps打開圖片素材

然后利用快捷鍵“Ctrl+J”復(fù)制一層圖層

然后選擇“圖層1”并點擊“添加圖層蒙版”

接著將前景色調(diào)為黑色，背景色調(diào)為白色

調(diào)好后選擇“畫筆工具”

調(diào)整畫筆工具的顏色為黑色，并選擇圖層蒙版

接著利用畫筆工具將背景擦去即可完成摳圖，如果不小心將圖像擦掉了，可以交換前景色和背景色在擦除即可還原

7、通道摳圖

通道摳圖適用于色差不大，外形復(fù)雜的圖形，像毛發(fā)及樹枝等。首先利用ps打開圖片素材

然后利用快捷鍵“Ctrl+j”復(fù)制一層圖層

接著點擊“通道”

選擇并復(fù)制一個圖像清楚的通道，如“藍(lán)色”

然后點擊“圖像”選項卡

選擇“調(diào)整”下的“色階”

然后調(diào)整色階以增強(qiáng)圖像對比度，調(diào)整好后點擊“確定”

接著選擇“快速選擇工具”

將圖像選中，邊界處可以放大在選擇

選擇好后點擊“編輯”選項卡

在彈出來的選項中選擇“填充”

將圖像填充為背景色即為黑色，點擊“確定”

然后選擇“圖像”選項卡

選擇調(diào)整下的“反相”將背景設(shè)置為白色

接著利用快捷鍵“Ctrl+J”復(fù)制一層圖層

接著將圖層1和背景的“小眼睛”關(guān)閉即可查看摳出來的圖像

8、反向摳圖

找到圖片，點擊打開。

點擊使用魔棒工具。

點擊外部空白區(qū)域。

點擊右鍵，點擊“選擇反向”。

再點擊右鍵，選擇通過拷貝（剪切）的圖層。

刪除背景圖層。

如圖，摳圖完成。

去水印技巧

1、使用仿制圖章工具去除

使用仿制圖章工具去除文字這是比較常用的方法，具體的操作是，選取仿制圖章工具，按住Alt鍵，在無文字區(qū)域點擊相似的色彩名圖案采樣，然后在文字區(qū)域拖動鼠標(biāo)復(fù)制以覆蓋文字。

要注意的是，采樣點即為復(fù)制的起始點。選擇不同的筆刷直徑會影響繪制的范圍，而不同的筆刷硬度會影響繪制區(qū)域的邊緣融合效果。

2、使用修補(bǔ)工具去除文字

如果圖片的背景色彩或圖案比較一致，使用修補(bǔ)工具就比較方便。

具體操作是：選取修補(bǔ)工具，在公共欄中選擇修補(bǔ)項為“源”，關(guān)閉“透明”選項。然后用修補(bǔ)工具框選文字，拖動到無文字區(qū)域中色彩或圖案相似的位置，松開鼠標(biāo)就完成復(fù)制。

修補(bǔ)工具具有自動匹配顏色的功能，復(fù)制的效果與周圍的色彩較為融合，這是仿制圖章工具所不具備的。

3、使用修復(fù)畫筆工具去除文字

操作的方法與仿制圖章工具相似。按住Alt鍵，在無文字區(qū)域點擊相似的色彩或圖案采樣，然后在文字區(qū)域拖動鼠標(biāo)復(fù)制以覆蓋文字，只是修復(fù)畫筆工具與修補(bǔ)工具一樣，也具有自動匹配顏色的功能，可根據(jù)需要進(jìn)行選用。

4、應(yīng)用消失點濾鏡法

對于一些透視效果較強(qiáng)的畫面(如地板)，可以應(yīng)用“消失點”濾鏡進(jìn)行處理。

操作方法是，框選要處理的文字區(qū)域，(防止選區(qū)以外的部分也被覆蓋)執(zhí)行菜單命令：濾鏡——消失點，進(jìn)入消失點濾鏡編輯界面。

1)選取左邊工具欄中的創(chuàng)建面板工具，由地板磚縫交匯處開始，沿著縫隙，依次點四個點，連成一個有透視效果的矩形。然后拖動其邊線向右方及下方擴(kuò)展，令面板完全覆蓋文字。

2)選取左邊工具欄中的圖章工具，按住Alt鍵點擊選取源圖像點，待顏色變化后，在文字區(qū)域拖動便完成復(fù)制。

人像磨皮

首先通過快捷鍵Ctrl+O鍵打開一張人物圖片，然后通過Ctrl+J鍵將圖片復(fù)制一層，在濾鏡菜單下找到“Neural Filters...”單擊打開。

先開啟“皮膚平滑度”按鈕，再調(diào)整“模糊、平滑度”數(shù)值，最后點擊確定，以智能對象方式輸出。

ps2021新增的平滑度濾鏡可以一鍵識別人物臉部，并進(jìn)行磨皮，還可以通過智能濾鏡進(jìn)行修改，效果與美顏相機(jī)類似。

圖片上色技巧

首先我們用ps打開圖片。

然后新建一個圖層。

將圖層混合模式設(shè)置為顏色。

接著選擇畫筆前景色。

然后在圖層上使用畫筆上色即可。
