我發覺偏光鏡映出來的相既色彩係飽和d，同時亦暗d，如果張相既ev提高番張相又會光d但色彩又冇咁飽和，咁會唔會如在映相時把ev刻意降低就會等同用左偏光鏡呢(撇開偏光鏡的其他用途黎講)

偏光鏡 主要唔係俾你當減光鏡用架喎,咪攪錯

我知，佢其中一個用途係令個藍天更藍，但我發覺當係後製時把ev增加後個天會白番，咁令我想起會唔會係映相時刻意減低瀑光便可做到偏光鏡既效果

Yes you may reduce the exposure to get bluer sky but the rest of the scene would be under exposed and become noisy. PL filter can avoid this.

Happy shooting !
