| p.1 #1 · Mixed Lighting ... WB Challenge |
Coming on the heel's of wrestling with Jim's Wyoming Rockies, this is from the same day as the Skyward image I posted.
Anyone that's been watching for a while knows that I really have this thing about "blue snow", "blue hair" etc. (OCD to some, I'm sure)
Anyway, I was shooting this as part of a test shot (series) to help illustrate some physics theories with someone who wasn't quite grasping my written explanations (different topic) ... go figure.
Anyway, as part of that endeavor, I recognized the opportunity to capture / illustrate the mixed lighting that occurs in nature that I'm always espousing about ... as the colors are reflective of the light that is naturally occurring.
The fence is entirely the same color (i.e. white) and as is easy to see, it is simply reflecting the light that is illuminating it, iaw with AI=AR (uh-oh physics geek warning ), The salient point here is to show that our subject is receiving light from "two" different sources. One being the direct (specular) warm sunlight, the other being the indirect (diffuse) cool skylight.
On many occasions, the sources are more "blended" together to create a homogenous source. And to a degree, the color of the direct light typically overpowers the color of the indirect light. But as our angles move around from 0 - 90 (and nearly 180 here) we encounter a greater degree of separation between them. As is the case with "golden hour" stuff, the luminance levels of the direct light is reduced, yet the indirect light remains essentially constant ... but relative to the other times of day, it now appears stronger as byproduct of less direct lighting influence.
So, here's the $64,000 question ...
How do you adjust WB to make the white fence ... white?
I'd like to hear & see what everyone's approach / opinion is regarding this. To borrow from Karen ... "Have fun"
