Here's a before and after with straight ambient vs composite. The composite consisted of a polarized layer and umbrellas with strobes illuminating the interior and clothing. The most drastic change affected by the polarizer was the yellow lighting reflecting off the wood floor. The polarized filter not only weakened the glare, but took out a majority of the yellow color cast too. To further minimize the yellow cast, I took out select areas with a desaturation of the yellow channel. Click the image to reveal a before/after slider.
