Next time you need to set your camera to compensate for tungstan lighting and use some form of flash. Anyway, dup, desat top layer (I like using Luminosity Desat for this), set that desat layer to 50% opacity and flatten. Now do an auto-level. I did do a few additional enhancments. Very noisey so I did the retoucher's trick (reduced the size to hide the noise; lol). Noise is your enemy with this type of capture. ![]()

Well, there's hardly any blue color whatsoever so I'm not sure how much of that can be recovered. If you have the original RAW files then you might be able to boost the blue using a plug-in such as UFraw. However, if all you have is the 8-bit JPEG files then about all I can suggest is the following:
The result will by no means be perfect, but it will at least make bright objects white and in my experience, this approach does a pretty decent job of handling skin tones. |

Just tried your technique Saul; not a bad result either (but of course still noisey). Thanks for the tip. ![]() |

There is a very efficient Gimp filter for that: http://luca.dealfaro.org/Whitebalance Basically, you use the color picker to set the foreground color from a spot in the image that should be neutral gray or white (the wedding dress, porcelain plates...), and you use the filter to "make the foreground gray". |

I did it the same exact way as Lyle did, except after auto levels i brought the dark parts of the image in to 20 and it brought out the colors more. ![]() Then duplicating the end result twice ,and setting the middle layer to lighten only and the top layer to overlay works nicely afterwords. ![]() Though the table clothe does look a bit blown out in some lighter areas. ![]() Result ![]() |

I find using G'MIC's anisotropic smoothing works well at removing noise, when used correctly (larger images most definitely required). |

Couldn't get it to work very well with this one Ofnuts (tungstan compensation usually is not just a simple color balance issue), but I know plenty of other scenarios where it will work. Thanks for the link. ![]() |

Post subject: | Re: yellow pictures |
i still wonder how the suggested fix will work on other images of same series The problem ,as Saulgoode already noticed is that there is almost no any blue, on that food image was not a big issue, blue were not too important there, ...but on cloths the effect may be much more visible @Rod you removed well the strong yellow cast but now there is a magenta cast |
