I did a lighting- and white-balance test to see how it affects skin-tones and wrote my findings down and made an example-image.
If anybody is interested in reading it, I posted it on my facebook-page:
I was surprised by learning that different light-sources affect skin-tone differently even if you white-balance to correct for their differences.
Is this a known issue?
Is it some effect of hue-twist caused by the built-in picture-styles?
Anyway, I'm a bit surprised about this, so I thought I'd share my findings and see if anybody has an explanation.
It isn't an issue, it is the very nature of light!
Ever wonder why good photo and video lights and computer screens cost more? Did you ever stop to and try to define a colour, in an absolute term? Ever look at a known colour, like a Pantone, in different colour spaces?
All light sources have spectral characteristics with spikes and troughs at different wavelengths, this makes for tonal differences irrespective of WB.
Actual colour science is an incredibly complicated thing and the apparent ease with which we see something, then illuminate it, photograph it, then try and reproduce that digital image either on screen or print is unbelievably convoluted, it's just the bulk of it goes on in the background without us ever being aware of it. Add in the fact that our cameras and our eyes see colour in a completely different way and you will be on the right track.
