PS 軟體是什麼?一分鐘了解 Photoshop 的核心價值

Photoshop 是 Adobe 自 1990 年推出的旗艦級 修圖軟體 Photoshop,至今已成為「影像處理專業標準」。若你正在搜尋「ps 軟體」或「photoshop 是 什麼」,先記住三個重點:

  1. 像素層級編輯 ─ 允許對每一個畫素做精準調整。
  2. 圖層與遮色片 ─ 支援非破壞式工作流程,方便回溯。
  3. 生態系完整 ─ 與 Illustrator、Lightroom、Firefly 等無縫整合,並有大量教學與插件。

Adobe 官方長期在 https://www.adobe.com/products/photoshop.html 公開產品白皮書與安全更新,為全球創作者提供權威技術文件。

修圖軟體 Photoshop 必學 8 大功能與實戰技巧

1. RAW 檔非破壞式編修

  • 使用 Camera Raw 濾鏡,保留動態範圍
  • 透過智慧物件轉換,確保後續調整可回溯

2. 自動選取主體 + 遮色片精修

新版「選取主體」運用 Firefly 模型,對髮絲邊緣辨識精度大幅提升。

步驟:選取主體 → 遮色片 → 邊緣調整 → 輸出至新圖層

3. 生成式填色 (Generative Fill)

輸入中文或英文提示即可讓 AI 補齊背景。對於社群貼圖延伸畫布特別好用。

4. ps 修 圖 軟體的「內容感知移動」

快速挪動人物位置並自動補洞,省去手動克隆。

5. 高階銳利化:智慧銳利化 + 高反差保留

先使用 智慧銳利化 去模糊,再用 高反差保留 疊加「柔光」混合模式,細節自然不過銳。

6. ps 繪圖用筆刷動態

  • 間距調整 1%,畫線更平滑
  • 使用轉盤壓感 → 筆刷形態隨壓力改變寬度

7. 3D LUT 與「漸層對應」打造商業色調

將常用品牌色存為 LUT,或透過「漸層對應」複製電影色彩。

8. 批次動作自動化

範例:為 300 張產品圖自動加浮水印
動作錄製 → 批次處理 → 指定輸出資料夾,30 分鐘工作縮至 2 分鐘。

色彩管理 CMYK/ICC RGB RGB RGB
AI 輔助 Generative Fill 基礎自動選取 一鍵換色、去雜物
系統 Win/Mac/iOS/iPadOS iPadOS Win/Mac/Linux Web

初學者常見疑問 FAQ

Photoshop 和 ps photoshop 有什麼差別?

兩者其實是同一軟體,ps 為 Photoshop 的縮寫。

My focus is ensuring it's under 160 characters while incorporating \"影片 修 圖\". I'm analyzing the post's core benefits and keywords to entice clicks.\n\n\n**Developing Draft Meta Descriptions**\n\nI've crafted two initial meta description drafts.
