The mid-tone was improved and now we can see the reddish Bougainvillea in the middle. Because of the poor quality of the original picture (it was taken from a phone camera) we can’t do much more about the definition but a lot more can still be done to enhance the picture’s color. In the next posts we will look at how to mask some parts of the picture so as not to affect the entire thing when applying changes. With that technique we should be able to retain the bluish sky and achieve a better contrast on the upper part of the scenery.中語氣改進，現在我們可以看到，紅色九重葛，在中東，因為質量差的原始圖片（這是從一個電話相機），我們不能做更多的有關定義，但有很多更仍然可以做，以提高圖片的顏色，在未來的職位，我們將會研究如何在掩蓋部分圖片，以免影響整個事時，申請的變化。與技術，我們應該可以保留藍的天空和實現更好的對比，上半部分的風景。

Also, a better way might be to enhance the picture using an automated script or software before applying the steps above. Using the Microsoft Office Picture Manager, I was able to improve the contrast of the picture but still the mid-tone is murky – it should be improved once the Photoshop tricks are applied.此外，更好的辦法，可能會以提高圖片使用自動腳本或軟件，然後再應用上述步驟。使用Microsoft Office圖片經理，我是能提高對比的圖片，但仍然中的語氣是陰暗的-應加以改善，一旦Photoshop的技巧應用。
