| 說明 | 數碼底片 (DNG) 文件格式是Adobe Systems所設計的一個免版稅RAW圖像格式。 | BMP文件格式是微軟Windows操作系統內部使用的圖形圖像格式。這些文件通常沒有壓縮，因此非常大。BMP文件的主要優點就是它們的廣泛接受，簡易性，和能在Windows程序裡使用。 |
| 優點 | 這個格式是Adobe為了回應用戶要求而設計的一個統一的相機RAW文件格式。數碼底片基於TIFF/EP格式，而原數據的使用是強制性的。 | 非常受歡迎 |
| 缺點 | 文件的大小非常大。沒有很多軟件能夠處理。 | 為壓縮，大的文件大小 |
| 元數據 | 處理XMP, EXIF 或 IPTC |
