Despite Jordan Star's well-meaning attempt to discuss color temperature
(that is, daylight vs. indoor lighting), all of today's modern digitals
include a function called "white balance." Simply hold a white sheet of
paper in front of the camera as you turn it on (even in room light) and the
camera will automatically adjust to the color temperature of the lighting.
That means your indoor shots without flash won't end up too yellow. The
better digitals include auto white balance, so they will adjust to almost
any lighting source to achieve a good-looking shot. Still, for accuracy,
the white paper (or even an index card) works best, though any shot can be
adjusted later using imaging software which is usually bundled with the
camera or with a high end application like Adobe Photoshop. Using 35mm
cameras means either adding a filter to adjust for indoor lighting or using
tungsten film (though you need an accurate color temperature meter to know
what temperature your lighting is on the Kelvin scale -- most tungsten
color film is blanced for professional lights which are about 5600K). If
you shoot slides using daylight film indoors, almost no amount of color
correction will eliminate the yellowish color cast. Hope this helps.

Best regards,
Jim
