The filters are usually, as I recall, 80a the corrects regular 3200 K tungsten to 3400K for tungsten film, 80b for using using daylight with 3400-3600K photoflood, then a deeper 80c and 80d. The problem is that the color varies with the voltage and wattage rating of the buld and what voltage it is used at. Typically- if your current may be anywhere from 100vac to 120vac- and the lower the voltage, the warmer the light. Also- some people and commercial establishments use commercial bulbs rated at 130vac, and under use at the 110v-120v- they last much longer, but they render a warmer light. Also- in restaurants- they often have lkights on dimmer switches- the light goes positively red at some low settings! I've shot with a noctilux at these low levels, and while the negative was 'printable', the color was as red as a baboon's butt and no amount of reasonable filtration, either on or off the camera would have made a difference! So- in short--- it all depends! It is a situation where there are so many variables, that unless you have a color meter on site, and a complete set a decamired filters like a motion picture shoot, you sort of have to take what you get. I still say that using an 80B will at least get you enought information in the blue sensitive layer that some reasonable correction can be made in negative film output. If I were using gel filters or CP filters, I would start with w 10C+25B with most household tungsten, but experiemtnation would be necessary for absolute correction values. Does anyone know if Gossen still makes their color meter?
