This brightens up the skin independently of everything else."
"I use Adobe Photoshop Lightroom* where you have the red, yellow, orange, green, blue, magenta and purple channels, and when desaturating those individually, you still have control of the luminance and brightness of each of those channels. So what it means is that when I'm photographing an Indian wedding, and you've got slightly darker skin combined with bright clothes or a decorated room, the brightness of those things will overpower the faces and the skin. So what you can actually do is push the luminance on the yellow, orange and red up slightly, because those are the key channels within skin tone. This brightens up the skin independently of everything else."
