| Sep 17, 2014 at 12:04 | comment | added | user2118622 | @MarkP yeah to bring down the orange. I pull down red twice as much as i pull down green. So that skin tone is shifted to yellow a bit. I also increase blue slightly. But in this process the stones become bluish. Now if i try to correct only stones, the skin tones become orange back again. Now, is it possible to white balance the image, without using mask to color correct each component (skin tones and stones or wall). | |

| Sep 17, 2014 at 11:15 | comment | added | user2118622 | @AndyBlankertz It is more exaggerated, when photographs are taken in sun; even when the background is green grass, tree leaves. White balance is a little better when taken in tube light, but there may be noise grains in that case. | |
| Sep 17, 2014 at 10:55 | comment | added | JenSCDC | Does this happen in every photo? I'm wondering if the neutral background in this one is throwing your perception of color off. | |

| Sep 17, 2014 at 8:19 | comment | added | Russell McMahon | " ... eyes and brain tuned ...". It can be argued that the actual colour changes when the irradiating source changes, as the response of the various target components to various wavelengths change. When we try to "colour balance" the image we are attempting to make it look as it would with illuminated with a standard source ("tungsten incandescent") and in fact if we look at the scene at the time the photo was taken it does not look to our eye as it would if we illuminated it with tungsten. Why should we be able to or want to modify the image in ways which do not represent reality. ... | |
