The many colors of photo
A wise friend of mine (orangbulu) always says, "Engineer doesn't read user manual".
So the shocking moment is when you realize that you use your stuff in a wrong way.
I thought I set my white balance right, until one day I realize there's one thing called "TINT" in lightroom that has been spoiling my color.
So I tried to correct it.
Then, another day while clicking randomly on Lightroom I found that Split Toning actually does a little more magic.
It's not necessary that photo 3 is better than photo 2 than photo 1.
Everyone has their own color preference.
But that just gave me some flexibility to play around, and to give the photo the right feeling.
