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.

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. ¶ÇÇÑ, ´õ ÁÁÀº ¹æ¹ýÀ» Çâ»ó½Ã۴°¡ÇÏ´Â ÀÚµ¿ÈµÈ ½ºÅ©¸³Æ®¸¦¾î³ª ¼ÒÇÁÆ®¿þ¾î¸¦ »ç¿ëÇÏ¿© »çÁø À§ÀÇ ´Ü°è¸¦ Àû¿ëÇϱâ Àü¿¡ÇÕ´Ï´Ù. microsoft »ç¹«½ÇÀ» »ç¿ëÇÏ¿© À̹ÌÁö ¸Å´ÏÀú, ³ª´Â »çÁøÀÇ ¸í¾ÏÀ» °³¼±Çϱâ À§ÇØ ¼ö ÀÖ¾ú´Ù Áß¹Ý - ¼Ò¸®´ÂÇÏÁö¸¸ ¿©ÀüÈ÷ È帰 - photoshop Æ®¸¯À» Çâ»óµÇ¸éÀÌ Àû¿ëµÇ¾î¾ßÇÕ´Ï´Ù.
