+# 峰值對焦如何協助拍攝
+
+無論您使用 DSLR 或無反射鏡相機，了解這種對焦模式如何使影像變得清晰以確保相片品質。
+
+![[Pasted image 20230426213513.png]]
+
+## 什麼是峰值對焦?
+
+如果您沒有在新相機上嘗試傳統的鏡頭是因為沒有自動對焦，那麼峰值對焦 (也稱為輪廓強調) 就是解決方法。峰值對焦是即時對焦模式，利用相機的「即時檢視」對焦輔助，在觀景窗中以假色覆蓋來強調輪廓對比區。這樣可以協助您在拍攝前決定影像的哪個部分在焦點內。
+
+峰值對焦起初是由錄影師使用，但是得利於現代技術的進展，已不再限用於攝影機，而是廣泛見於大多數的靜止數位相機。所有較新型的無反射鏡相機都具有此功能。如果您擁有的是 [DSLR 相機](https://www.adobe.com/tw/creativecloud/photography/discover/dslr-camera.html)，這個功能的名稱可能是「即時檢視的對焦輔助」。
+
+由於此效果只能在光線抵達感應器後啟動，您也可以使用較舊的手動鏡頭來進行峰值對焦。「即使您使用的是沒有此功能的不同相機，它也完全不難做到，」攝影師 Patricia Davidson 表示。
+
+![[Pasted image 20230426213534.png]]
+
+## 峰值對焦的運作方式
+
+峰值對焦所根據的原則在於，一個影像最亮的區域會有高對比，在「即時檢視」顯示中物件的邊緣和紋理會呈現明亮的白色或彩色。一種演算法會即時分析影像，當一個物體進入對焦區時，鮮明的邊緣會在該圖片的特定區域產生密集曝光。
+
+然後一個假色圖層會覆蓋在該區域。在大多數的相機中，您可以根據自己的喜好設定覆蓋顏色並變更偵測的敏感度。
+
+![[Pasted image 20230426213547.png]]
+
+## 峰值對焦的用途
+
+峰值對焦讓攝影師能以比典型即時檢視法更快的速度，將手動鏡頭對焦。它很適合用於很難迅速評估對焦區域的場景。在光線昏暗或很難用肉眼適當對焦的情況下進行拍攝時，這個功能可以派上用場。
+
+如果您不想使用自動對焦來捕捉移動緩慢的物件，如在空中移動的雲，那麼峰值對焦會是適合採用的技術。您還可以用它來為鏡頭找到適當的景深，但要注意調整，包括您的 [ISO](https://www.adobe.com/tw/creativecloud/photography/discover/iso.html)。
+
+「您通常會把它設得較高或較低，」攝影師 Jason Weingart 表示。「如果您在拍攝[淺景深](https://www.adobe.com/tw/creativecloud/photography/discover/shallow-depth-of-field.html)的鏡頭，如 1.4 f-stop，那麼最好將峰值對焦的敏感度設高一點。這樣不會有太多清晰的物體，效果較好。如果你在拍景深真的很深的鏡頭，那麼可以把敏感度設得低一點，使更多東西變得清晰。」
+
+**選擇手動，而非自動  
+**峰值對焦讓您可以運用許多手動鏡頭，這使得手動對焦變得更加輕鬆自如。「一般在使用手動對焦時比較常使用它，自動對焦較少用，因為在手動對焦時可以在轉動對焦環時看到不同區域突顯出來。在手動對焦時使用它的好處比自動對焦時多，但是無論是哪一種對焦當然都可以使用它，」Weingart 說。

+
+## 對焦
+
+在立即用數位相機測試之前，先了解峰值對焦的四個要素以使你的下一張相片精彩無比。
+
+1. 峰值顏色：
+    在相機的設定選單，自訂峰值以符合需要捕捉的場景。舉例來說，修改增強輪廓的顏色以便與影像形成對比，讓輪廓變得更加清晰可見。
+2. 峰值等級：
+    除了顏色以外，還可變更下一張肖像照的峰值等級。一般而言，有兩到四個選項可供選擇，等級越高會產生越清晰的輪廓，而等級越低則越需判斷。
+3. 切分影像：
+    如同測距器和舊裂焦螢幕，切分影像是一種「即時檢視」對焦輔助。進行切分影像時，對著影像旋轉對焦環，直到影像的不同部分對齊。
+4. 放大:
+    要知道捕捉的影像是否清晰，唯一方法是在「即時檢視」模式透過光學觀景窗放大所有細節。使用峰焦對焦或切分影像並做到最好，然後放大影像以便修飾焦點位置。

+## 峰值與谷值
+
+在某些情況下，並不建議使用峰值對焦。當相機鏡頭的景深特別淺時 (1.2，全片幅) ，最好不要使用。在這些情況下，所需捕捉的場景太淺，即使最好的演算法可能也無法精確顯示出最清晰的區域。
+
+**著重正確的事物  
+**“「峰值對焦是相機內可用的絕佳工具，可讓你在外拍攝時盡量取得最清晰的影像，」Davidson 說。「在後製處理期間，當我用 [Adobe Photoshop Lightroom](https://www.adobe.com/tw/products/photoshop-lightroom.html) 或 Photoshop 處理影像時，這只是讓我不必擔心清晰度而已。」
+
+如果在野外沒有獲得想要的結果，您可以使用 Adobe 應用程式中的 Adobe Photoshop 建立圖層並調整影像清晰度。 在 Lightroom 中匯出和編輯這些影像，然後在工作時將它們來回順暢地移至 Photoshop。峰值對焦可以替您節省一個步驟，但有了 Adobe，您總是可以在後製期間進行更多必要的調整。
