Is there any way to set the white balance for a shot with light from two different light temperatures?
To make the photo look like it only has one light temperature?

If you mean can it be fixed in post, yes, it often can. But it depends on the image.

OP Can you show us a shot of what you mean?

Here is a small part of the image in question, there are actually a batch of these all with the same problem:
I think there are actually 4 temps; sunlight, florescent, and incandescent, and the camera's flash.
Plus there is a lot of blur too.
It was taken with a Canon EOS Rebel T1i, here is the EXIF:

It would be easier if you had shot in raw... Best thing to do is use a correction gel on the flash and or only use sun/flash and incandescent or florescent but try to stay away from multiple temps in the future. At this point I am not even sure what you could do to fix it without playing with it. Hopefully some of the others here can help get you close... I also shoot with a T1i but can't say I've had this issue yet.
Also, you should go into the software and register your name in the camera so that it stays imbedded with the file as long as the exif data is attached.
Best of luck,

When using flash and ambient light, use a gel on the flash to match tne ambient....when there are two lightsources you can't adjust, (daylight and artificial light in one shot), you can do a double rawconversion and use masking

I didn't take that shot and it wasn't my camera, I was working with a photographer who was new and part time.
I was just wondering if there were any "filters" or "plugins" (I use GIMP) to automate corrections like multiple light temperatures.

I'd suggest that too. Anyway, there's no easy fix for a problem like that. You can use local adjustments for the white part (acting as back light?), for example and then use adjustment for the whole image to lower the temperature, make it colder.

In Adobe Camera RawCS5 or6 or Lightroom 4 with either a raw, tiff or jpg you can use the adjustment brush and selectively brush the proper color tempeture into the areas that need adjusting.

That does sound kind of manual?
I use GIMP and I used a brush with a hue and then a color merge mode to adjust the hue and then color so both sides of the object (the arms) match the same color temp.
Is that the same approach?
