注意規則第5項說的，
5- Originality, image processing, and composite images :
- Minor burning, dodging, color and exposure correction is acceptable. Cropping is acceptable. Fish-eye lenses are acceptable. High dynamic range images and stitched panoramas are acceptable only if the combined parts are taken at approximately the same time and with the same setting. Digital composition of a series of photographs taken successively at the same location with the same lens pointed in the same direction, for example to create a digital star trail image, is acceptable. Any other changes to the original photograph not mentioned here are not acceptable, and will render the submitted photo ineligible for a prize.
- Composite images made by combining images taken at different locations, different times, or using different lenses are ineligible.
大致翻一下
剪裁是可以接受的。魚眼鏡頭是可以接受的。高動態範圍圖像及縫合全景圖是可以接受的只有合併後的部分採取大致相同的時間，以同樣的設置。數字組成的一系列照片，先後採取了在同一地點以同樣的鏡頭指在同一方向，例如建立一個數碼星跡的形象，是可以接受的。任何其他改變原有的照片這裡沒有提到是不能接受的，並會使提交照片為獲獎資格。
- 綜合的照片，照片相結合的圖像在不同地點，不同時間，不同的鏡頭或使用不符合資格。
為了表現出現場的感覺，搞下去吧!
