Hello,

I run across the latest editorial for Vogue Paris by Inez&Vinoodh:

They mostly use flash and manage to have the background go blue. Now, I am wondering if they gel the flash and the white balance it to obtain that blusihn tone on the background only or if it is just an overlay in post production, or kind of both. interestingly, enough the model seems to have bluish skin tone as well..

Thanks

That's tricky to get right in the camera. You would need to set the WB to turn the background blue for whatever time of day that you're shooting. Then warm gell the flash to reverse that cold WB.
Or you could gell the lens blue & gell the flash warm to do the same thing.
He probably took hundreds of shots, so it would be a PITA to do it in PS, but it could be done that way, too.

The theory is easy: Set camera WB to 3200K, light the model with an incandescent source...

  • 3200K setting causes background which is lit in shade to go bluish
  • 3200k setting cause subject to be slightly warm if lit with 2900K ordinary incandescent, or subject will be 'neutral' if lit with 3200K photoflood lamp



The practice of the theory will vary based upon the time of day and the kind of light falling into the space in terms of the degree of bluishness, but the subject lighting is predominantly driven by the color temp of the supplemental lighting. Using flash, simple to put a full CTO filter in front of the flash!

Not to hijack this thread but since it's on the same topic...

How did this photographer get everything so yellow? Is it all in post?
