[Lightroom 教學] Develop: 旋轉,切裁,除塵與照片比較

2007, 10月 12 3:30 am

各位還記得 Library 模組內的 Toolbar 嗎?同樣的在 Develop 模組內也有 Toolbar﹐但兩者的功能則有些差異。Lightroom 將 Library toolbar 內一些常用的功能也放在 Develop 的 toolbar 內﹐像是 Color Label﹐Rating…等等。但這些都介紹過了﹐要跟各位分享的則像是切裁﹐旋轉﹐去除塵點與比較照片…等功能

Develop Toolbar
▲Toolbar 位置與說明

切裁照片(Crop)

點選上圖所示的「切裁」按鈕 crop icon,則會進入切裁模式中,可看見 Toolbar 右方多出了許多小圖示,其中,按下 crop tool 則可於照片中拖曳選取想切裁的範圍,另一種方式則是拖曳於照片四周的「調整外框」。

crop adjust frame
▲調整位於照片四周的選擇範圍,亦可達到切裁照片的目的

若想要於切裁時,能夠固定長寬比例,則可以按下 lock ratio 圖示,使它變成 lock ratio lock ,然後再選擇右方選單中的比例選項,則可以依照您所選的比例下去切裁。

拉直與旋轉

拍攝照片時,一不小心容易輕微歪斜,則可以利用圖中的拉直工具 straighten icon,並於圖中找尋您覺得是水平的線條,並拖曳之,則可以自動幫您調整旋轉的角度。

▲利用拉直工具來調整照片水平

若想要隨心所欲的旋轉角度呢?

點選 toolbar 的 crop icon 進入切裁模式後,將滑鼠移至「調整外框」的外圍,此時滑鼠指標會變成如下圖所示的樣子:

Rotation mark
▲旋轉照片

此時則可以按住滑鼠左鍵,就可以旋轉照片了 :-)

另一種方式則是使用拉直工具旁邊的 slider, 如下圖所示:

Rotation slider

向左則是逆時針選轉,向右調整則是順時針。上方亦會顯示目前的旋轉角度。

去除塵點

以往拍完照片發覺照片上有 CCD 塵點時﹐往往還得進入 Photoshop 做善後處理﹐如今 Lightroom 整合了這個小小的功能﹐讓您編修照片的流程更為方便!

於 toolbar 按下 Remove Spot Icon 後﹐點選照片塵點處:

removing spot
▲去除塵點的步驟

Lightroom 會自動幫我們選擇取樣處﹐但若選擇至錯誤的地方﹐我們則可拖曳取樣圓圈﹐選擇更好的取樣處。另外有分兩種取樣方式﹐一種為直接複製 (clone) ﹐另一種 heal 則是會考慮到塵點與取樣處的光線差距。各位可以選擇您覺得較好的方式。

除此之外﹐因為塵點面積不一﹐還可以透過拖曳的方式﹐調整塵點處圓圈的大小喔﹐各位不妨試試看!

附帶一提﹐去除塵點工具可搭配批次處理的方式(Sync)﹐讓一系列的照片可同時消去固定位置的塵點。

照片比較

在編修照片的過程中﹐一定會想得知編修前後不同之處﹐以往我的做法就是按下「上一步」與「下一步」的熱鍵來切換觀察﹐到底做了這個改變有什麼不同呢?而 Lightroom 很貼心的內建了 Before/After 比較修圖工具﹐讓我們不用在用這種笨方式來比較照片囉!.

於 Toolbar 按下 Compare Icon 後﹐編輯區域會出現左右兩邊的比較視窗(此時才知道大螢幕的好處 @_@)﹐左邊為 before 右邊為 after。若您是第一次按下比較照片的圖示。則 before 會出現剛匯入照片時的樣子﹐而 after 則是目前正編修中的情況。

當然比較的視窗不只有分成左右兩邊一種﹐還分成上下﹐或是單一圖片上下分裂比較和左右分裂比較。各位可以試試看﹐在此就不多介紹。

而 Lightroom 的 Before/After 當然不會這麼單純﹐只能比較上一次和現在的設定﹐使用者可以於 History 面板(記錄編修過程的面板)中﹐選定想要比較的歷史編修過程﹐並按下右鍵﹐選擇「Copy History Steop to Before」﹐即可將將歷史步驟套用至 Before。

Hitory -> Before
▲選擇想套用的歷史步驟

Lightroom 還提供了幾個好用的工具﹐讓我們能於 Before/After 之間互相交換設定值。

Before/After Icons

當進入 Before/After 模式時﹐於 toolbar 會看見如上圖的幾個按鈕。 很簡單的﹐最左邊的按鈕就是將 Before 的設定 Copy 給 After﹐中間則是將 After 設定 Copy 給 Before﹐最右邊則是交換設定。

當您與 Before 做比較時﹐發現比較喜歡 Before 的樣子時﹐則可以按下第一顆按鈕﹐將設定 Copy 過來。

您也可以在編修某選項前﹐按下中間的按鈕﹐先將設定 Copy 給 Before ﹐再進行編修。

以上就是這次 Toolbar 的內容囉 :-) 若有疑問或是錯誤請盡量提出!

有個笨問題,截切完… 要怎麼縮圖呢?

SILENCE 回應此篇文章 於 2007, 10月 12

縮圖是在 Export 時調整喔!
可限制長和寬的pixel

很棒的教學,已經在期待下集了~ ^^

Jason Sung 回應此篇文章 於 2007, 10月 25

很棒的教學,最近是挺想看看LightRoom,對於類似的軟體,我對除塵的部分很感興趣,不過相較於Aperture起來,在這個部分LightRoom好像不是很方便用,畢竟是類似於Photoshop中的蓋章工具。除了這個之外LightRoom的功能似乎都還蠻不錯,有機會想體驗一下處理速度如何。

感謝你的分享囉!

andy 回應此篇文章 於 2007, 12月 10

您好 我想請問
文內寫到的拉直工具
不曉得在哪
我一直都找不到可以調角度的東西
謝謝

andy 回應此篇文章 於 2007, 12月 10

對了,想順便問
lightroom選起來的圖
有辦法進行一次刪除嗎?
我每次按delete只能刪一張
這樣的速度實在很慢,謝謝

SILENCE 回應此篇文章 於 2007, 12月 16

andy,
要先進入切裁模式中才會出現拉直工具的icon
當然可以一次刪除多圖囉, 請在library模式底下選取,再按delete

mars 回應此篇文章 於 2010, 2月 1

可以請問
Lightroom2能否在相片上加入水印或文字
這問題我找了好久仍未找到答案

想要留言嗎?
