When I took sunrise pictures this morning, the clouds around the sun were orange. But when I actually took the pictures, the clouds came out white. If the whole picture came out white, then it’s over-exposure which is not in this case. It’s only the clouds around the sun came out white. I tried to adjust the white balance to shade, but then it turned out yellow. SO HOW DO I OBTAIN THAT RIGHT ORANGE COLOR IN THE PICTURE?

這是白平衡的問題.用自動白平衡的話相機會盡量將畫面調成中性色調,就會好似你講咁啲雲變咗白色,唔夠氣氛.用預設白平衡係一個辦法,我通常都係用日光白平衡,對比度同飽和度再加小小影日出,日落.用陰影我覺得太假喇,會好似加咗橙色瀘鏡咁.淨係影太陽就OK,如果有前景就會連啲剪影位都橙晒.
言歸正傳,要調出啱心水的白平衡除咗用預設白平衡外,其實仲可以用手動或者K數輸入.手動即係搵將白紙對住光源,然後用相機對住張紙話俾相機知這是白色.不過一來你唔可以擺張紙去太陽側邊,二來個結果可能又係啲雲變晒白色,所以這方法行唔通.用K數邊影邊微調比較可行,但好可惜1000D係冇呢個選項的,要較高級既型號先有.
而且K數亦唔係百分百準的.佢只係照顧到藍色及琥珀色(橙色)中間既變化,洋紅同綠色係唔理的.所以有時會發覺點調都出唔到正確既白色,一係偏藍,一係偏橙.
所以你會發覺1000D既白平衡微調裏面有晒四種色既微調,仲有正負9級咁多.可能你揀個接近既預設白平衡,然後再慢慢試真係試到都未定的.不過這該是很痛苦的事情吧?試得來個太陽都已經太光影唔到.
最好既方法都係影raw,再事後用跟機個軟件調啦,幾仔細都得,續K較都冇問題.除此之外,仲可以微調曝光,對比,銳利度,飽和度等,我覺得影raw係對提升照片質素必經之路.
雖然用raw點調白平衡都得,但我依然建議拍攝時盡量用接近既白平衡影,因為白平衡都有小小影響曝光的,偏橙會同時偏暗,當一較翻啱時就會曝光過度,相反偏藍就會偏光.相差太多會影響你對曝光的判斷.
