I want to achieve accuracy
The first photo is how my eye saw it and the camera captured it.
But the second one is supposed "white balance corrected".
Which one is more accurate then?
The joys of white balance, especially away from the presets.
I am interested in your term "white balance corrected"
By what means?
I'm being pedantic, but what did you reference off of in the scene?
When it comes to sunsets and sunrises you would really need to white balance manually every 10s to be technically correct.
But at sunset and sunrise that would lose the impact of that magic hour light. And besides, if the suns dipped, you aren't colour metering off of the light source, but reflected light source bouncing off of clouds and the sea, or your card is facing the wrong way etc etc.
So whats the answer to your question.
At magic hour there isn't really one.
A preset of daylight up until streetlights kick on will probably be accurate.. to your eyes recollection.
A preset of flouro will probably serve you well enough when lights kick on, until the sky is all indigo.
It's therafter a question of setting for the right source, 2000k for sodium, 3200k for incandescent..
Aesthtically I prefer the colours of the first one. When theres high contrast betraying the position of the sun (i.e. low) I would just set to daylight and roll with the punches. Unless you are shooting scenes of crime.
