    I'm taking a portrait shot with 2 lowel omni halogen lamps, with 35 mm
    slide film. My question is... what film is best advised for this kind of
    light, or if I were to use daylight film, which I already have, what filter
    should I use... Thanks Sami

    Can't comment on the film, but you'll have to use an 80A filter. The filter
    will cut 2 stops of light.

    Halogen is tungsten filament in a halogen gas. Same color temp as far
    as I know. (3000 - 3300K). "Photographic" tungsten lamps are
    "supposed" to be 3200K. (The "blue" photo lamps are about 5000K, but as
    they age (quickly) they go "warmer" in tone (cooler temp).

    You could use T film (usually expensive) or filter with 80A or 80B blue
    filters. (80A -> 3000K to daylight film;
    80B -> 3300K to daylight film)

    If you you have to use a "B" with a 3000K light, then the shots will
    look slightly warm;
    If you you have to use a "A" with a 3300K light, then the shots will
    look slightly cool;
    (or did I get the above backwards?)
    In any case, even if you miss between 80A and 80B the effect will be
    very minor.

    For the 80A, the filter factor is 2.4 (or about 1.3 stops)
    For the 80B, the filter factor is 2 (or 1 stop).
    (If TTL, then it doen't matter).

    Cheers,
    Alan

    I have largely moved away from using Tungsten films, though one good choice is
    Kodak Ektachrome 64T. Be aware that you still might need to use colour
    correction filtering, though using this film should be about the closet match
    to your lighting.
