Color reversal film is also known as color positive film. It is slide film only. Sometimes somewhat accurately called tungsten film. Photographic film not made of tungsten but balanced for the colour of light from a tungsten bulb. ie: the film assumes that light from a tungsten bulb is white. Most commonly available as type B, which has a colour temperature of 3200K. Less common is type A film, which has a colour temperature of 3400K. Tungsten film is usually slide film, though more recently tungsten-balanced print film has become available. Kodak makes (or did, not sure if they still do) a 500T color negative film. There are also corrective filters to use for incandescent lighting such as a Wratten 85. The other alternative is the very effective way of color correcting your standard color film images in Photoshop.
