I would like to figure out how to remove some of the yellow from this shot using a filter. I have been told "Tungsten" film would produce true colors but I don't have any and I do have filters.
Wikipedia says a #80 (saw #80A, 81, and 82 listed in other places) will allow you to shoot tungsten light with daylight film - so it stands to reason that it might give you a similar effect of shooting this scene with tungten balanced film. PM me if you want to know how to fix it with other means.
Filters on a camera lens, or color gels over the light source(s) may also be used to correct color balance. When shooting with a bluish light (high color temperature) source such as on an overcast day, in the shade, in window light or if using tungsten film with white or blue light, a yellowish-orange filter will correct this. For shooting with daylight film (calibrated to 5,600 K) under warmer (low color temperature) light sources such as sunsets, candle light or tungsten lighting, a bluish (e.g., #80A) filter may be used.
80A would be the most typical filter to shoot in tungsten light with daylight film. You might need something a bit stronger, depending on the light source.
Thanks. Yes Rick. I am a violin maker. This shot was cropped to only show the back. I was in the process of being varnished when I took this shot and the neck had been taped off so I didn't want to show the blue masking tape.
