| 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。 | TIFF是個有靈活性的圖像格式，通常保存24位或48位的每色8位或16位（紅，綠，藍）圖像。TIFF的靈活性可說是好處也是壞處，因為沒有一個圖像閱讀器能夠完全處理TIFF的所有種類。TIFF可以是有損或無損。有些TIFF文件提供較好的二值圖像無損壓縮（黑白，無灰）。有些高端數碼相機擁有可以把圖像保存為TIFF格式的選項，採取的無損壓縮算法是LZW。TIFF圖像格式雖然並不廣受網絡瀏覽器的支持，印刷業卻廣為接受TIFF為照片文件的標準。TIFF能夠處理特定電器的色彩空間，例如特定印刷機墨水的CMYK設定。 |
| 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。 | LZW無損壓縮功能 |
| 缺點 | 文件的大小非常大。沒有很多軟件能夠處理。 | 大的文件大小 |

What Canon cameras shoot CR2?
CR2 was used by most Canon DSLRs and some PowerShot models from 2004 to 2018, including the EOS 5D series (Mark II, III, IV), EOS 6D, EOS 7D, EOS 80D, EOS Rebel/Kiss series, and EOS-1D X Mark II. Newer Canon cameras (EOS R series) use the CR3 format instead.
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.
