| 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。 | 差不多所有數碼相機都會有把圖像保存為JPEG的選項。JPEG格式支持每色8位（紅，綠，藍），文件大小也比較小。只要不使用重度壓縮，圖像質量不會受太大的影響。不過JPEG文件如果不斷被修改，保存的話，很有可能會退化。若您計劃以後修改照片圖像，或不能接受圖像失真，把它們保存為非JPEG的無損圖像格式的話會比較好。話雖如此，JPEG大致上是最適合網絡發佈的格式。 |
| 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。 | 小的文件大小，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。 | 質量損失 |
