    shooting with tungsten light source

    I've heard that shooting with tungsten light source makes a film (B+W) underexposed about 1/2 stop if I expose the film accoding to meter reading. Is it true? thanks susumu

    shooting with tungsten light source

    It depends on the spectral sensitivity of the film (and meter). Many of the films that are "panchromatic" are a little deficient in response on the red end of the spectrum, add to this the possible metering errors in reading the light, and you can be off by 1/2 stop or more.

    I'll second Wayne's reply. Kodak used to give recommended daylight speeds and Tungsten speeds for their films. FI Tri-x is rated as 400 ISO in daylight and 320 ISO for Tungsten.
