There is a special time when critters like to come out, just before sunrise and right after sunset. This light is incredibly soft, non-directional, and nearly shadowless. It is also mostly blue. That color cast, cold color cast can either be a plus or a minus depending on the story you want to tell about your subject. In this case, it’s a minus.
There is one odd thing about my vision, I see that blue color cast when I’m out shooting. Real old training from the days of film and using CC filters. When I see this, I tend to change my White Balance in camera to get the photo right with that click (In this case setting it to 8200k). That’s because when the image comes up in PhotoMechanic, I want to see the correct image, not the image before it need to be corrected.
If you move the slider back and forth above, imagine if all you saw the “cold” photo, a whole bunch of them in your image browser. What would your opinion of those “blue” images? Now move the slider to the “warm” shot in the camera correct image. How do you feel now about that photo, a whole browser full of cute Bambis?
While you have the twilight blues when you’re shooting, there is no reason why you have to have them when you look at those images in your browser. The call is all yours :-)
