: Can you use halogen work lights (i.e., from Home Depot) to light a black & white portrait? Do I need special film or special filters?
Usually for b/w film there is no big difference between daylight and tungsten light. But it depends on your objects - the warmer tungsten light will have an effect similar to a warming filter, i.e. impurities of the skin will probably show less.
There are some b/w films which are more suitable for use with tungsten light than with daylight. I remember having read this about the (extinct) east german Orwo NP27 which was heavily red-sensitive and could be used with an ASA setting around 800 (instead of the nominal 400 at daylight) with tungsten light.
There are also some films like the Kodak Tri-X Professional (available in 120 format only, not to be confused with Tri-X Pan) which are specially designed for studio lighting and will compensate for extreme contrasts such as deep shadows and highlights which will not be found with open air lighting.
