It may not be as bad as this...
While technically the strong filters are required to correct tungsten
light to daylight balance, I find the result unnaturally cold-looking.
A weaker filter, such as an 80C or D will partially correct, but leave
some pleasant warmth - and requires considerably less cost in
effective film speed. 'Course, if using color negative materials, it
is easier - just overexpose about 2/3 stop, and ask the printer to
correct the color balance (this works well with flourescents,
too - though the resulting color balance may also not be
technically correct).
