| 說明 | 使用 Canon 數碼相機拍攝的RAW照片。它的圖像信息完全依照攝像頭傳感器所拍攝的原本情況，不含有任何壓縮或色彩調整。 | 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 | 未經過任何處理，讓您能在修整圖像色彩平衡，曝光等問題時擁有跟多的靈活性。 | 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 |

What is the difference between CR2 and CR3?
CR2 is Canon older RAW format based on TIFF structure, while CR3 uses the modern ISO Base Media File Format. CR3 supports C-RAW (compressed RAW) for roughly 40% smaller files and faster writing speeds. Both preserve full 14-bit sensor data for editing.
