Mixed white balance

[Juandent]

Hi,

I have a shot of a commercial office which has a mixture of white balance (see attached). Inside there is some sort of fluorescent or tungsten while the outside is receiving sun light through some windows. The shot as colors render an unpleasant color palette where the red and yellow sign above the door looks more magenta and the yellow is desaturated. Inside, the colors are greenish and the whole is just not appealing.

The original image is a RAW.

Any help will be appreciated!!

Thanks,
Juan

After a quick viewing of the thumbnail, it seems that the WB issue is well confined to local areas, inside office and outside. So, a quick and easy adjustment of the RAW to create two images, one WB adjusted for the office interior and the second image adjusted for the rest of the image.
Post process by adding a layer mask to the WB exterior image and mask out the office space showing the WB interior image.

Hi,
Yes, it sounds easy... I have tried some of this. The problem is there are a lot of reflections in the windows and also what to do with the window frames... there is a lot of selecting particular areas that make this approach very time consuming even though it is very appealing in theory.

any suggestions as to HOW make your good idea a reality (i.e. it sounds great and simple, but it is VERY labor intensive!!)

Regards,
Juan

About 5 minutes. Would do better on original RAW.
If pixel peeping, then it would take a long time, depends on what you consider acceptable. If you are assessing every pixel or if a print at 4x6.

Changed WB to correct interior of office, layer mask to reveal as appropriate.


Alternately BW, therefore no WB issue.
