I don't know about a specific filter, but basically Tungsten film raises
the kelvin response of the film about 2500 degrees. Tungsten is about
3200 degrees and daylight is about 5500-6000 degrees. I would think
that by boosting the yellow channel (actually lowering the blue channel)
you should be able to resolve most of this problem. I'd expect any
image program like photoshop could do this for you. You might need to
play with the hue as well to get more accurate color results.
